Q: The manufacturing process of plastic products? Who knows?
1. the manufacturing process of plastic products, that is, the processing of plastic bottles, refers to the process of making the final plastic products from polymers made from synthetic resin manufacturing plants. 2., processing methods (and plastic processing), including: plastic (Molding), extrusion (extrusion), injection molding (injection molding), blow molding (hollow forming), rolling and so on. Detailed manufacturing process flow:(1) press molding: molding or pressing forming. Plastic molding is mainly used for molding phenolic resins, urea formaldehyde resins, unsaturated polyester resins and other thermosetting plastics.(2): extrusion, extrusion molding, extrusion machine is used (extruder) will be heated by continuous resin mold, extrusion method of desired shape. The extrusion molding sometimes have to thermosetting plastic, and can be used for foam molding. The advantage of extrusion is that it can extrude various shapes of products. The production efficiency is high, it can be automated and continuous production. The disadvantage is that thermosetting plastics can not be widely used in this process, and the size of products is prone to deviation. (3) injection molding: injection molding. Injection molding is an injection molding machine (or injection machine) that uses thermoplastic melts to be injected into the mold at high pressure to cool and solidify the product. Injection molding can also be used for the formation of thermosetting plastics and foams. Injection molding has the advantages of high production speed, high efficiency, automation in operation, and the ability to form complex parts. It is especially suitable for mass production. The disadvantage is the high cost of equipment and moulds, and the difficulty of cleaning of injection molding machines.
Q: Which plastic is suitable for processing 3mm threaded holes and is best resistant to corrosion?
Nylon plastic is suitable for processing 3mm thread hole, nylon is widely used in chemical machinery, corrosion protection equipment, gear and parts, broken material.
Q: Plastic machinery plastic pellet production process _ particles recycled plastics particles
1 、 polystyrene foam particle thermal insulation brick2 、 foamed granule mixing lightweight soil and production method thereof3. The process of producing a ball of bow shaped plastic filled with particles4 、 plastic particle preheater5. Continuous crystallization method and device for plastic particles6, waste floc manufacturing method of CA plastic particles and its special drawing machine7. Low dust particles of plastic additives8. Inorganic pigment particles for coloring plastics, lacquers, and building materials and methods of producing the same9. Equipment for depositing particles, materials, or soil on a plastic film that extends over the surface of a landfill or other location10 、 plastic particle melting filter core11. Method for making cutting plastic film granule cutter12. The preparation method of granulated auxiliary agent for plastic processing13, plastic pipe, particle seat cushion14 、 inner container, plastic pipe, particle seat cushion15 、 clothing made of foam plastic as interlayer filling material
Q: Would you please use the collected nylon and plastic film to wash them and machine them?
The particles are collectively called colloidal particles". Mainly used in the quality of plastic products are not demanding. Such as cabbage tube, Christmas leaves etc..
Q: Want to buy an injection molding machine to do some plastic products, equipment about how much money ah? What needs to be prepared?
Tens of thousands of yes, but the quality of the product to do the Department of stability, and later maintenance costs are very expensive, but also trouble, or choose the brand well. Investment step in place.
Q: Such as "computer embroidery processes" - Programming - sample preparation, shipment packing production computer
Process flow of plastic products1. Preparation before moldingA, grain preheating and drying: if the grain is affected with damp, it should be dried;B, insert preheating: in order to reduce the gap between the cooling shrinkage value of metal and plastic, the larger metal insert should be preheated.C, barrel cleaning: when changing the product, changing the raw materials, cleaning cylinder is required.2, injection molding process feeding - plasticizing - injection - holding pressure - cooling - die opening piecesA, feeding: each feeding should be quantitative, in order to ensure uniform plasticization;B and plasticization: the grains are heated to a molten state in a barrel;C and injection: the injection molding machine uses a screw to inject molten plastic into the mold cavity;D, keep pressure: after the mold is finished, maintain the pressure for a certain time;E and cooling: keep cool for a certain time in the mold cavity;F, mold opening parts: mold open, take out the product.3, plastic parts after treatment: plastic parts after treatment:A, remove the fly edge, material handle.B, inspection and packing.
Q: Which kind is with a lid, hollow, a little like PP material, white is a little transparent. It used to be filled with oil or wine. How is it processed? What company has custom-made?. Need to make the tank.
Blow molding die processing, general plastic products manufacturers should have the ability to produce.
Q: What kind of equipment does the plastic product factory need?
The current plastic, if the raw materials and semi-finished products are relatively low profits, it is recommended to do directly in the above color printing, the added value of high. Like universal printer, you can achieve this effect. In some plastic shell, plastic, plastic stationery and other top brands.
Q: I'd like to know all the machine names in the plastics processing industry.I would like to ask the professionals to give me some reference materials or tell them directlyThanks very much。
If the company more money, can choose Japan's machinery, Niigata, Japan steel, Toshiba, machinery, precision parts also voltage better, don't choose oil press, less stable.To save some domestic, Haitian machine is OK, the price is relatively moderate.
