FAQ

What chemicals should be used in plastic products?
Additives mainly in the following categories:OneAntioxidantsAntioxidantUnsaturated double bonds in plastics are absorbed by oxygen atoms, heat and lightCaused by breaking, resulting in free radicals, which cause a chain reaction, so that the molecular chain scission or formation of chain cross-linking,Resulting in lower or weaker strength of plastic products. The function of antioxidants is to delay the oxidation of plasticsBreak down and prolong the life of plastic products. The antioxidants used in the plastics industry can be divided into functions: (One)Inhibitors of oxidative chain reactions, such as alkylphenolAlkylPhenolButyl tolueneButylatedHydroxytolueneAbbreviationBHT) aromatic aminesAromaticAmines) phenyl - -B-Resistant amine(Phenyl-B-Naphthylamine), were of Kun (AlkylQuinoneAlkenyl bisphenol A(AlkyleneBisphenolAlkyl phenol sulfideAlkylPhenolthioetherSalicylic acidBenzene fingerPhenylSalicylateAnd so on) etc..

Every time I look for work on the Internet, I am confused. What kind of industry does the plastic belong to?..
According to the latest "national economic industry classification (GB/T 4754-2011)", the plastic products industry belongs to the C category manufacturing industry, the 29 major categories of rubber and plastic products industry, and the 292 category of plastic products industry.First, manufacturing is interpreted as "this category comprises 13 to 43 categories, refers to the physical or chemical change after a new product, whether it is power machinery manufacturing, or Handmade; and whether the product is sold wholesale or retail, are regarded as a variety of manufactured goods and parts in building production should be as for manufacturing, but in the pre construction site are the main components of products, assembly, warehouse equipment, railway bridges and highway, elevator and elevator, pipeline equipment, water equipment, heating equipment, ventilation equipment and air conditioning equipment, lighting and wiring assembly activities, and building the device are listed for the construction and manufacturing the categories include mechanical and electrical products, the scrap auto parts, engineering machinery, machine tools and other batch production process of professional repair, remanufacturing production Products to achieve the same quality and performance as the new products".
What plastics products are used in daily plastic products?
What do you want to see the plastic products, such as water pipes, electric wire slot need is extruder; plastic film, plastic bags and other needs is the film blowing machine; plastic bottle blowing machine; like most plastic stool, pots, barrels, and other appliances to the injection molding machine shell.
What kind of equipment do we need? How much is the approximate cost? Seek your heroes guidance and guidance!
Equipment include: film blowing machine, bag machine, punching machine, printing machine, etc., to invest one hundred thousand up and down, but also need a few tons of raw materials as a turnover, and then start production, I do not know very well, just listen to someone else said...
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.
How much do you need for it? How about the raw material?
The production of plastic sandals is the use of injection molding machine, injection molding machine in general to choose 500g-1000g, matching plastic crusher, drying machine, injection molding machine that usually adopts water cooling mold, also need cooling water system.
What are the features of plastic injection gears and machined plastic gears?
Injection of better, smooth finish, smoothness can be done on the mold, the strength is also good. When machining, some of the transmission, the edge may be very difficult to process, very beautiful
I haven't done it before, and I don't know how to do it Would you please tell me how to do this? How to do it? Good to do
First you need to recover some of the waste plastics, and then processing the plastic grain, in this process, you will also find a good sales channels, you can find some plastic products factory, plastic grain demand to talk about things and they are. You need to buy some advanced machines for processing plastic particles, so as to ensure the quality of the plastic particles.
