PVC Plastic Double Pipe Extrusion Production Line with Conical Twin Screw Extruder

Q: What are the plastic products used in heavy trucks, and how do they form?: There are several forming methods commonly used. First, calendering calendering for thermoplastics. It is through Plasticating plastic, sent to several groups of parallel arrangement, reverse rotation of the heat roller, by repeatedly calendering products. Production of film or sheet. Two, casting casting use dry plastic. It is soluble in the solvent of plastic, due to weight andspread to continuous operation of the metal belt, become thin layer of uniform thickness, then heating apparatus soft volatile agent, curing products, production of film or sheet.

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's the price? How much does it cost to run a processing plant? What's better about that one?: 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: Would you please use the collected nylon and plastic film to wash them and machine them?: I found that the 2 floor is the way out. Do not know their cloud ah.

Q: where there are advanced environment-friendly recycled plastic processing equipment?: Environmental protection recycling plant, this is a systematic project, the use of granulation machine is usually used granulator, need to be matched with waste water filtration, sedimentation, purification treatment pond, waste gas purification equipment.

Q: I did not come into contact with the plastic design, to understand the mechanical design and traditional design of plastic parts and fittings of the (metal material) are different, from what kind of material, design, drawing standards, labeling etc.. Please engage in plastic design industry heroes pointing!: The difference between plastic parts design and mechanical design:1: Material: mechanical design is mainly involved in metal materials, plastic is non-metallic, the performance is very different.2, standard: plastic parts with a metal parts of different implementation standards, accuracy is relatively poor, with the relative precision, tolerance range selection is different, marking basically the same, slightly characteristic.3: Connection: plastic parts connection and metal parts connection, compared with its characteristics, generally used: card, buckle connection, insert connection, thread connection, deformation, connection, etc..4 and other: the most important parameters in the design of plastic parts are shrinkage calculation and deformation control, as well as the determination of taper and slope parameters for injection molding.

Q: 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".

Q: Where has the machine which sells the plastic processing, wants the true, begs the answer: What should I do? I have an injection molding machine here

Q: Please expert pointing. How high is the profit?. Where are the machines reliable in quality?.: Profit is not to say, 2000 before doing a ton of 500-1000 net profit, now do a ton of only about 300, but also to do good, large amount of the profit was also lower (puerile) now what things are transparent, not hide what the difference, and too many fakes (it is impurity) also, the factory debt, lead to large investment (scrap price is high, the factory as a result of the large investment in arrears), reliable quality machine: if the water feed on a number of Shandong (lack of the low yield), if the dry material (sheet) on a number of Guangdong Zhongshan presses, the Chinese star can also.

Q: What kind of machine does plastic products factory use to produce plastic products?.: Method and process hand-painted are mostly used in small workshops and small factories, a little larger factories with pipeline production process (also adopted in a small number of custom hand-painted products processing or production).
