Large injection molding machine to make good use confidential data breakthroughs in core technologies

http://injection-molding-machine.tayu.cn/injection_molding_machine/527.html

Large injection molding machine to make good use confidential data, we need to break through the core technology categories

The first is how the injection molding machine data management problems. After the massive injection molding machine machine type data such as time series, spatial and temporal high-speed data acquisition is complete, it needs to survive, this relates to data valid packing, compression, issue placed. Data survive it is to be used, which requires support queries to quickly locate the data application requirements, which in turn is an example of how to establish efficient spatiotemporal data indexing problems.

Better manage data stored, the next question is how to support a variety of analysis. Did people know the actual analysis, the analysis is much more than a bunch of algorithm development issues. Algorithm is only a small part of the work, most of the work is based on the understanding of the business problem to select the data needed to understand the characteristics of the data, and then design an appropriate model and algorithm based on the characteristics. This understanding of the characteristics of intermediate data big machine data is very difficult. Because the machine data can not be an intuitive understanding of the human need to interact with feature projects. In addition, from the perspective of models and algorithms, machine data is often a physical world system of perception results, and the physical world there are many mechanistic principles exist, such as mechanical fields of mechanics, metallurgy fields of chemistry, so the injection molding machine analysis of large-scale machine data requires an organic combination of mechanistic models and statistical models. Another often overlooked issue is data quality problem - how to grasp the quality of the data, how to fix data quality.

Angle talk application, how to more easily access and use of data analysis, especially for experts in the field. In the multi-source heterogeneous data, mask data integration problems associated with such experts in the field do not need to understand the complexity of big data technology and programming.

Plastic injection molding machine to solve the problem of air bubbles generated inside the tube

http://injection-molding-machine.tayu.cn/injection_molding_machine/529.html

Plastic pipe extrusion, we often encounter a series of problems. In addition to possible plastic tube surface cracks will appear, black lines, moire phenomenon than we may also encounter inside a plastic tube produced a bubble, then under what circumstances, will produce plastic tube inside the bubble it ?
Plastic pipe inside bubbles, in general, is related to the moisture content of resins and additives. If the water is too high, then the plastic tube pipe bubbles will be porous.

Attention to this problem, we just need the moisture content of raw materials is controlled within a reasonable range can be, general raw material moisture content is controlled within 0.3% -0.5% range. Injection molding machine in a high speed mixer can exclude only the water portion of the raw materials compounded when, at the same time when we store the raw material for stacking the choice of location is to be noted that, especially in the rainy season should pay attention to prevent material moisture. Damp PVC resin can not directly fire baked, in order to avoid thermal decomposition of the resin, the baking, if desired, add some stabilizer in advance. After high speed mixing materials in storage after the rainy days, it must first be used only after drying.

If we find the injection molding machine plastic tube inside the bubble, then the die temperature should be slightly lower at the point of extrusion speed can not too fast, in order to eliminate air bubbles inside the plastic tube. And, while cooling in shape when flash is not suitable for rapid cooling, in that case, plastic pipe will be prone to bubbles.

Of course, this is the main reason for the plastic pipe extrusion produce bubbles, does not rule out other causes. There also may be due to excessive or inappropriate financial material inflatable plastic exhaust pipe leading to the residual gas, so treat specific conditions!
When plastic hose appears scorch marks, wrinkles, mainly from the extrusion process. Extruded plastic tubes extruder screw diameter of 45-65mm, an aspect ratio of 25, a compression ratio of 3-4.

Plastic pipe extrusion, plastic hose extrusion temperature is generally higher than the hard plastic pipe extrusion temperature is lower. If the die temperature is too high, then the injection molding machine plastic pipe appears scorch phenomenon; if the injection molding machine die temperature is too low, then the plastic tube surface brightness difference phenomenon.

If the extruder screw speed is too slow, then the plastic tube surface prone to moire; if pulsation extrusion, injection molding machine plastic pipe so prone to the phenomenon of bamboo-like; if the injection molding machine screw speed is too fast, then the surface of the plastic pipe mouth friction between the mold overheating can cause the product surface scorch phenomenon. Therefore, the screw speed can be selected within 20-40r / min range.


Similarly, if you pull too fast or too slow will make the horizontal and vertical injection molding machine plastic pipe contraction increased, the surface will be prone to wrinkles. Thus, pulling speed according to the different diameter plastic pipe, make appropriate adjustments. For example, the diameter of 9-16MM plastic tube traction line speed can be selected within 8-12m / min range; 19-25mm diameter plastic tube traction line speed can be selected within 4-8m / min range.

Plastic pipe extrusion, we want to pay particular attention to the injection molding machine die temperature, extruder screw speed and traction speed and other factors, so as to prevent the injection molding machine plastic pipe extrusion scorch the surface, the appearance of wrinkles.

Europeans, they are very valued member of our team, but they claimed to possess the future was uncertain. "

Keith Freegard Polymers Axion general manager position, workers from Eastern Europe in the past 15 years, the UK's vertical injection molding machine industry has made a considerable contribution. It adds: "Many processors with maintenance engineers regard the family moved to the UK, this is a positive way to contribute to local economic development, at present, in my opinion, how to deal with these kind of workers worried about is the moment the most important thing."

Summit Systems COO Keith Bailey for investors worried about the moment, its statement:. "There are a lot of customers are hesitant to invest in the face before, we will want to stop to see what happens."

Material dealers Plastribution also due to fluctuations in exchange rates, its business is affected. Mike Boswell general manager position: "with the expected exactly the same, with the depreciation of the euro against the dollar, pound, resulting in vertical injection molding machine of plastic raw material prices, which in July sales is very significant."

Injection molding machines Operation

http://injection-molding-machine.tayu.cn/content/?513.html

Injection molding machines can fasten the molds in either a horizontal or vertical position. The majority of machines are horizontally oriented, but vertical machines are used in some niche applications such as insert molding, allowing the machine to take advantage of gravity. Some vertical machines also don't require the mold to be fastened. There are many ways to fasten the tools to the platens, the most common being manual clamps (both halves are bolted to the platens); however hydraulic clamps (chocks are used to hold the tool in place) and magnetic clamps are also used. The magnetic and hydraulic clamps are used where fast tool changes are required.

The person designing the mold chooses whether the mold uses a cold runner system or a hot runner system to carry the plastic from the injection unit to the cavities. A cold runner is a simple channel carved into the mold. The plastic that fills the cold runner cools as the part cools and is then ejected with the part as a sprue. A hot runner system is more complicated, often using cartridge heaters to keep the plastic in the runners hot as the part cools. After the part is ejected, the plastic remaining in a hot runner is injected into the next part.

Plastic injection molding machine industry an urgent need to control the speed of capacity expansion

http://injection-molding-machine.tayu.cn/injection_molding_machine/504.html

With the adjustment of domestic industrial structure, plastic injection molding machine supply pattern transformation, PE in production capacity accounted for five common plastics from second place in 2011 fell to third place in 2015, and gradually to the production of PVC, in five common plastics production capacity in the proportion fell sharply.

2011 PVC production capacity in the proportion of five general-purpose plastics 45%, followed by PE production capacity accounted for 22%, PP production capacity of slightly less than PE, ABS with production capacity accounted for PS were 6% with 5%. 2015 the annual PVC capacity expansion speed is reduced, while the PP capacity expansion faster, PVC production capacity accounted for reduced to 36%, PP production capacity accounted for 28% of the added value, increase the proportion of PE production capacity to 24%, ABS with PS capacity expansion is relatively slow, ABS with PS capacity accounted for 6% of domestic production as well as comprehensive health imports, calculated five general-purpose plastic self-sufficiency rate. Overall domestic production capacity to keep the amplification, from 2011 to 2015, five general-purpose injection molding machine plastic self-sufficiency rate has increased, PVC self-sufficiency rate increased by 8% to 99%, PP self-sufficiency rate rose 11-78 percent, ABS self-sufficiency rate increased by 10% Zhi 62%, PS self-sufficiency rate increased by 7% Zhi 73%, PE self-sufficiency rate increased by 1-58%. PVC with PP high self-sufficiency rate, mainly due to the PVC with PP production capacity is large. PE PVC self-sufficiency rate is less than with the PP, the main if restrictions on domestic supply structure, more reliance on certain imports, mainly divided with the price dependent on product type dependent, dependent on the price of the main Middle East if the low-end products a price advantage, product type dependent If the main South Korea, Japan and other high-quality bias, the presence of domestic supply gap in the product. ABS, PS domestic consumption is limited, with the amplification domestic production capacity, self-sufficiency rate is gradually increased.

Plastic injection molding machines from five common marketing model look, PE with PP direct relatively high rates were above 40%, while ABS with PVC direct relatively low rate of self-sufficiency rate is not higher than 30%, if all the main injection machine plastic products customer groups, differences in financial capacity and customer distribution center.

2016 Central Economic Work Conference stand to production, to inventory tasks, PVC to productivity developments are more significant, while the PP capacity expansion plan is still more, if not controlled in time amplification rate PP production capacity, PVC currently is PP tomorrow. In terms of relative PP, PE of capacity expansion rate is relatively low, PE with PP larger spread, the spread in the East China 1800 yuan / ton. From the price level five common plastics injection molding machine the current point of view, the price is inversely proportional with the capacity, ABS production capacity is relatively small, capacity expansion more slowly, ABS prices higher than 10,000 yuan / ton; while PVC production capacity of the largest domestic supply a larger pressure surface, PVC price less than 6000 yuan / ton.

China's economic growth into the shift of the speed reducer, domestic demand for commodities affected the domestic commodity supply growth should be synchronized adjustment. But only control the speed of capacity expansion, product prices can be relatively strong, otherwise only the excess deeper quagmire, the market is hard for better performance. The plastics industry is imperative to control the speed of capacity expansion, adjusting the industrial structure, according to end-user demand, on-demand production, enhance the technological content of products, increase the added value of products.

Physical properties of thermoplastic - injection molding machine

link: http://injection-molding-machine.tayu.cn/injection_molding_machine/498.html

Can the physical characteristics of plastic injection molding machines after the thermoplastic molding their secondary processing into thermoplastics and thermosetting plastics, this process is suitable only for injection molding machines available for secondary processing of thermoplastics, such non-crystalline plastic separator crystallinity categories. Highly crystalline plastic mechanical strength, heat resistance, but poor transparency, a plastic such as polyethylene, polypropylene, polybutene-1, poly-4-methylpentene-1, polyoxymethylene, polyamide, polyester, polyvinylidene chloride, fluorine plastic, chlorinated polyether. Non-crystalline plastic mechanical strength is poor crystalline plastic, but the heat resistance and transparency, this kind of plastic polyvinyl chloride, polystyrene, ABS, PMMA, polycarbonate, polyphenylene oxide, polysulfone and the like.

Different types of plastic, although having some similarities, but personality differences, be sure to do the proper selection of products or aids simulation time can produce compliant products. The temperature of the distillation column by gasoline gasoline temperature adjustment control back flow display by the rotameter. Light diesel gasoline distillation bottoms.

Injection molding machine thermoforming mold thermoplastic molding plaster molds and tin mold needs. Only the transition plaster mold is a mold, the final mold is manufactured of tin.

Because gypsum hemihydrate and water after water into gypsum (CaSOO), gypsum plaster water solubility than half a much lower solubility, gypsum constantly condense, and hemihydrate gypsum continues to dissolve, eventually all turned into gypsum, in the process of change, all the excess water to evaporate. Because the condensation was gypsum volume increased by 1%, so with plaster made of male and female mold, the inner and outer surface smooth, easy to crack tin mold.

Tin melting point of 231.85 ℃, ordinary tin ingots in the crucible of iron melts very easily, and most of thermoformed plastic optimum molding temperature of 120 ~ 220 ℃, so the male and female molds made of tin with a qualified majority of the heat molded plastic processing, for polysilicate, nylon, oriented polyester, polysulfone plastic, optimum molding temperature exceeds 231 ℃, is available, lead, tin, antimony alloy (80% lead, 10% tin, antimony 10% ) made mold forming. Consider shrinkage plastic injection molding machine, the design of the die size to be bigger, so that the final size made accurate parts.

Colored plastic injection molding machine in order to make plastic products with a desired color can be added organic dyes or inorganic pigments in plastics, the former mostly with good miscible resin suitable for transparent products manufactured; the latter in the resin dispersion very good, the system is suitable for transparent products.

Commonly used organic dyes are: 1) azo dyes (including insoluble and poorly soluble), such as aniline yellow, light yellow, golden red C, Li Rubine; 2) phthalocyanine pigments such as sodium Costello Blue Mongolia , Mona Los Tello green.

Commonly used inorganic pigments are: 1) class chrome yellow, the color with the mixture in an amount depending, PbCrO higher the content of the deeper the color, there are lemon yellow, orange chrome yellow and red chrome molybdenum; 2) cadmium pigments cadmium yellow, cadmium red, cadmium selenide; 3) iron oxide red iron oxide, iron oxide yellow, iron oxide black; 4) class titanium dioxide, barium titanium white, titanium white calcium; 5) carbon black. Above dyes and pigments are easy to buy.

The method of plastic mixed colors, with red, yellow and blue as the primary color, with a group called the secondary color hue to another color, other colors redistributed between the secondary colors called tertiary colors.

Various components with different content in plastics, color hue, lightness and purity are also different. For example: secondary colors: red + yellow = orange red apricot red + blue = purple Qinglian color dark pink yellow + blue = green grass green sky blue light color green emerald three color: orange + purple = brown, purple + green + orange = = gray olive green color, blue + yellow + red = brown. In order to improve the plastic and the filler imparting new properties to plastics, usually filling to a powder in a plastic or fibrous filler. Plus plastic clay, mica, asbestos, talc, etc., can improve the rigidity of the plastic, temperature resistance; plastic clay was added after the sintering can be improved insulation; plastic paint can be increased by adding wood flour affinity; plastics Carbon Black can improve the aging properties of plastic; plastic plus copper, aluminum can improve the thermal and electrical conductivity.

Injection molding machine production apparatus of the present process of self-made culverts induction furnace, induction furnace is made based on the principle of electromagnetic induction. Furnace surface is bounded to the heating coil is placed in the furnace core culverts below the surface to be heated tin mold placed over the surface of the furnace. Furnace surface is non-permeable sheet (asbestos or ceramic plate). In a multi-strand copper wire wound heater wire to circle through frequency or high frequency alternating current. When the furnace is not placed face to be heated tin mold, the cooking surface side alternating magnetic field of the magnetic circuit is substantially air magnetic resistance greatly. At this point only a small heating coil in the no-load current. When tin mold to be heated placed on the induction furnace, most of the air had been replaced by a soft magnetic iron magnetic circuit reluctance is reduced, an alternating magnetic field greatly enhanced.

Alternating magnetic field to generate a lot of eddy currents die tin, tin obtained heat mode, temperature rise. Make melt molding plastic injection molding machine. The size of the induction furnace power depends on the size and processing aids may be ,, generally designed to 1kW and 2kW two, the power supply system can be designed as a single-phase or three-phase type two kinds.

The production process for the production of a Fresnel lens as an example. Fresnel lens is an optical element having a stepped surface. Adjacent ladder smaller the pitch, the more accurately meet the conditions reduce the residual aberrations at a smaller lens thickness. Stepped up to the smallest pitch 0.05mm, the ladder can be concentric, spiral or parallel grooves. The first two cases are part of a stepped cone or a sphere. Case 3 is a planar or cylindrical portion.

Plastic Fresnel lens made of poly methyl methacrylate (PMMA).

1) Select the flatness of the glass piece is placed on the platform, the Fresnel lens mold or wood stick to the original flat glass, cardboard and used to do a paper circle around.

2) with a camel hair brush to remove dust on the Fresnel lens ring, and in its coat of thick soapy water.

3) The humidity adjusted too uniform hemihydrate gypsum poured circle paper, dried, torn paper circle Serve plaster mold nightside.

4) on the plaster mold nightside slightly trimmed, coated with thick plaster male mold translated into soapy water.

5) the plaster male mold kerosene smoked black circle around on paper, translated into tin die.

6) The colorless, transparent plastic granular fill in the blank die in tin, in the induction furnace pressure to a flat stainless steel plate, adjusting the current heating, which is formed into a Fresnel lens on its surface.

Injection molding machine mold parts maintenance, where to do

source:http://injection-molding-machine.tayu.cn/injection_molding_machine/474.html
"Each injection mold required for injection molding machine annual maintenance program position, depending on the mold cycle. Here are some maintenance tips injection molding machine mold parts, allowing each user to ensure that the injection molding machine hot runner mold, heating effective runner, guide posts and thimble, molding inserts, such as mold components to prevent accidents from happening.
1. Check whether the injection molding machine at the aeration holes have early warning of rust or damp phenomenon
If you find the hot runner near the discharge vent rust or damp phenomenon, it means that internal condensation, or water may be broken in the injection molding machine. Damp phenomenon will lead to a fatal short circuit heater. If the injection molding machine is not running endlessly throughout the year, we need to shut down in the evenings or weekends, then the probability of occurrence of such condensation increases.
2. Remember to alert the operator not to heat the nozzle head at the gate of the injection molding machine "clean" out
If the operator happen to see die at the outlet of a small piece of stainless steel, there may be a point nozzle assembly. "Clean up" out of this seemingly impeding things often ruin head hot mouth. In order not to damage the injection molding machine hot mouth, please before taking action to confirm the type of nozzle head hot runner system, and to ensure that all operators are well trained and can identify different types of mouth own head contact.
3. The injection molding machine sliding stop button
For the year endlessly running machine, this work should be done once a week. And the end is a very good opportunity to give these parts a routine lubrication and maintenance.
4. The resistance value of the cross-validation of the injection molding machine heater
You should start using the heater when it has been measuring its resistance value, it is the end of the year again, when measured and compared. If the resistance values ​​are ± 10% of the float should consider getting a replacement heater to ensure that it does not fail at the critical moment of the production process. If it has never been measured initial resistance value, so now measured once, and the resulting value is used as a reference for future examination of the data when the heater.
5. Check the injection molding machine and injection molding machine guide pin guide bush whether there are signs of wear
Looking for scratches or abrasions and other traces of mold parts that wear due to lack of lubrication caused. If traces only just appear, you can also give the injection molding machine and injection molding machine guide pin guide sleeve plus lubricant to prolong its life. If wear is very serious, it should be replaced with new parts up. Otherwise, the cavity and core portions may not be a good fit, resulting in different parts of the cavity wall Bohou.
6. Check the flow of water injection molding machine
Connect a hose in an injection molding machine at the exit of the waterway, to let the water through the pipes to the bucket. If you do not clear out of the water or the color, there might be rusty phenomenon, which means that the water is not smooth blockage somewhere. If you find that these issues will be drilled through all the pipes again (or you take any of the methods most commonly used to clean up), in order to ensure the smooth flow. Improved plant's water treatment system that can prevent the emergence of various problems caused by the rust and blocking future.
7. Clean the injection molding machine thimble
After a year's time, thimble and a film due to gas accumulation of impurities becomes dirty. Mold cleaning agent recommended some good cleaning every 6-12 months. Clean, and then coated with a layer of lubricant on the thimble to prevent scratches or breakage.
8. Check whether the hot mouth radius fracture region
Fracture is left in the machine loose hot mouth hardened plastic debris by clamping force from the cartridge assembly in the forward injection caused. Cause of the problem is also possible that the centerline is not aligned. When the fracture was found, to consider both possibilities. If you have suffered damage severe enough to prevent leakage when the petals (a term used by the previous user mold means between the thermal head in the mouth of the guide sleeve and the emergence of machine plastic leak), it should be replaced sprue bushing.

Injection molding machine operating cost comparison: USA VS China

source:http://injection-molding-machine.tayu.cn/injection_molding_machine/468.html
    Recently published an official Plante & Moran PLLC Company in the management report of the Forum, said that although the United States injection molding machine operating costs than China, but the United States thanks to stable energy prices and energy costs and China's rising wages, the gap between the two countries shrinking.

    Ted Morgan, senior consultant manager at the accounting and management consulting firm said it expects operating costs of the injection gap will continue to narrow. China's price advantage more displayed on small tonnage vertical injection molding machine. In terms of large-tonnage injection molding machines, with the United States is very close.

    Plante & Moran company of its 2013 North American plastics industry survey said the hourly cost of the machine data further indicate that automation will help reduce China's low labor costs of the main advantages of industry consensus.

    Morgan said the key lies in the degree of automation vs. die after how much amount of work there, as well as investment products, the number of labor force.

    Morgan said that Mexico on small tonnage injection molding machines cost price between the United States and China, the United States large-tonnage machines and roughly. North America will become a powerful basis for production in Asia back to shore.

    Plante & Moran firm to represent the United States with Indiana injection molding machine operating costs. As the representative of China in Shanghai. In a 200-ton injection molding machine and a 2013 Digital 3000 t injection molding machine for comparison. These figures include only the injection molding machine operating costs per hour. Other services not included in the cost of Chinese production, such as transportation and supply chain extension costs incurred.

    Two points are energy and labor. China and Mexico real estate costs are also rising.

    China 200 tons injection molding machine at rates greater advantage, 35% lower than the US dollar 37.35 per hour, vs. US $ 50.40 per hour Indiana. The main reason is that in the small-tonnage injection molding machines, labor costs a large proportion of total costs, so the Chinese advantage.

    Morgan said the Indiana high labor costs than China high utility costs.

    2010--2013 years, Shanghai's hourly earnings rose by 76.5%. US labor costs are relatively stable. But Morgan cautioned that not exaggerate this trend. He pointed out that Indiana labor costs are still 2.5 times that of Shanghai.

    The case of 3000 tons injection molding machine is different, only 12.5% ​​of lower costs in China, Shanghai US $ 157.86 to $ 177.53 per hour vs. Indiana. One reason is that labor costs are large tonnage injection molding machines accounted for only about 30% of total costs, much lower than the proportion of small tonnage injection molding machine. Electricity running expenses occupy large tonnage injection molding machine in a large proportion of China's electricity and more expensive.

    3000-tonnage injection molding machines are also other more important factors in terms of cost.

    Morgan said there are very different cost of ownership. For large-tonnage injection molding machines, buying a large expenditure, but also requires a lot of fixed assets to provide support, space is also large.

    The US shale gas exploitation are given more advantages the United States to cheaper utility costs and energy costs to operate vertical injection molding machine.

    Morgan said the well-known Chinese utility bills much higher than in the US, but also rapidly rising.

    He believes that the US utility costs will remain stable. With the shale oil and shale gas exploration prospects so optimistic.

    Mexican manufacturing rapid economic development, in 2012, foreign direct investment of $ 12.6 billion in investment in manufacturing more than half. The rapid development of manufacturing industries including aerospace, automotive, electrical and electronics.

    Manufacturing workers' average hourly rate of $ 5 in the Mexican production of 200 tons of injection molding machine more competitive than Indiana - eastern Mexico to $ 45.91, while the US is $ 50.40. But in both 3000 ton injection molding machine is substantially flat.

    Morgan said that the cost of real estate in Mexico is higher than China.

    Morgan said the United States may be the molder Mexico as a "long-term threat" to their business. Mexican population younger, eager to catch up economically. But Mexico still faced with the mold resin production industry and supply base problem of limited, are being taken to enhance the practitioners of engineering and technical skills.

    He said that Mexico's injection molding machine operating costs will continue to be close to US levels.

    Morgan added that China's manufacturing industry will be more supply the domestic market, to a certain extent, to reduce dependence on exports.
