- Q:What are the processes and machines used in the manufacture of plastic products?,
- In recent years, the proportion of plastic products is increasing rapidly in many fields, such as household appliances, instruments and meters, building materials, automobile industry, daily hardware and so on. The requirement of high precision and high performance of plastic products increases with each passing day, which makes the precision forming technology progress constantly. Injection molding is one of the most important plastic forming methods, and many factors affect the precision injection molding. 1. in the early stage of the design of plastic products, injection molding materials should be selected according to their application environment. 2. precision molds, rational design of precision injection mold is the basis and necessary prerequisite for precision products. Precision molds are indispensable to produce precision products. The precision of the die is usually affected by the temperature control of the die, the precise manufacture of the die and the choice of the plastic shrinkage when the die is designed. 2.1 control of the mold temperature due to the effect of mold temperature on shrinkage molding, but also directly affects the mechanical properties of plastic products, can also cause various defects of product surface flooding, so must keep mold in the specified temperature range, but also to make the mold temperature changes over time. In the injection molding of general precision parts, the temperature of the die is controlled mainly to increase productivity. But the impact of temperature control of mold for injection molding is great, it affects parts of the shrinkage, shape, crystallization, internal stress, so the design of mold hot loop temperature distribution at the request reasonable precise control accuracy, the best use of mold temperature machine and cold water machine control.
- Q:What machine does the pattern design of this mass produced plastic product use?
- Hello, let me answer the question for you: you can open your mobile phone, Baidu, and then enter your current location, and then enter the address you want to query. The Baidu maps will automatically navigate the nearest route for you.
- Q:Can you make plastic bottle equipment for high profile?
- There are two kinds of plastic bottles: injection, blow and blow.Injection blowing is the two step, that is, injecting the bottle embryo first and then blowing it into a bottle. The machine mainly has the injection molding machine and the bottle blowing machine and the auxiliary machine and the corresponding mold.
- Q:What kind of equipment and materials do you need for a plastic packing bag processing plant?
- In addition you want to buy plastic granules, is the raw material, it will take a lot of money, do normal plastic factory funds can not be less than 100 thousand. As for the procedures that the business, tax, health and other general procedures. What the production process there is no serious pollution, blowing process will have plastic taste, but in your yard outside is not to hear.
- Q:What plastic has good machinability? Just get on the lathe.
- Plastic pipe on the market PVC find, building materials market is more than, can be mechanical processing. The tool before and after grinding angle of large points, especially the front angle and edge angle, more sharp knife arc.
- Q:Modified plastic processing, it is intended to refine and then double screw.
- It seems that you are not made of plastic yourself, so don't do it blindly, so as not to make money, spend time, make a pile of waste, and then lose a lot.
- Q:ABS plastic processing flow
- ABS resin is a three element copolymer developed on the basis of modification of polystyrene resin. A stands for acrylonitrile, B for butadiene, and S for styrene. ABS resin has three components, the comprehensive performance of A can improve the oil resistance, chemical corrosion resistance, which has a certain surface hardness; B ABS showed a rubbery toughness, improve impact toughness; S ABS plastics showed good fluidity, which has a good performance of thermoplastic plastic molding processing. ABS plastic is mainly used in the manufacture of instruments, instruments, household appliances, telephones, TV sets and so on. ABS plastic is used to make metal luster, and ABS is used instead of metal. Our factory produces various types of refrigerator liner and all kinds of plastic products, ABS injection products accounted for more than 88% of the total refrigerator plastic products
- Q:PC and PC alloy plastic surface effect which better, which good processing, and what are the other differences?
- The plastic processing of PC alloy PC alloy, in order to improve the mechanical properties of other plastics and the incorporation of PC raw materials, such as PC/ABS, PC/PA, PC/PS and so on, area is PC as a reinforcing agent with other plastics.
- Q:Plastic processing process
- The purpose is to beautify the surface of plastic products, usually including: mechanical modification, namely with filing, grinding and polishing process, the removal of parts on edges, burrs, and fixed size; finishing, including coating surface parts, the use of a solvent to surface brightening, covered with patterned thin film surface; colour. Including painting, printing and printing; metal plating, including vacuum coating, electroplating and chemical plating method etc.. Among them, the hot stamping is heated, under pressure, the hot film on the color of aluminum foil (or other pattern film) transferred to the workpiece. Many household appliances and building products, daily necessities and so on use this method to obtain the metal luster or the wood grain and so on the pattern.
- Q:What milling cutters are used for processing plastics?
- In fact do not wear too to pay attention to the water to keep up. Try to use high speed low cutting depthThe speed is 8000/, the cut depth is 0.3-0.4, and the 4000 is the best
