What are the common processing methods for plastic products?
Plastic processing, also known as plastic molding processing, is a composite of synthetic resin or plastic into plastic products. It is a large production sector in the plastics industry. Using ethylene as the main raw material, propylene copolymer, 1- butene, hexene, catalyst, polymerization or gas phase polymerization process by slurry, the resulting polymer through flashing, separating, drying, granulating process, to obtain the product of uniform particle. Such as sheet extrusion, film extrusion, pipe or profile extrusion, blow molding, injection molding and plastic.
Using this processing method: rotational molding materials are generally crushed into powder, and the melt flow during thermal cycling;Film: PE film processing, general blown film processing or flat extrusion method.
There are 5 main processing methods:1, for the production of plastic extrusion grade generally has less than 1 of the melt index and wide width to MWD;2, blow molding: more than HDPE1/3 sold in the United States for blow molding purposes;3, injection molding: HDPE has several unclear applications, ranging from reusable thin-walled beverage cup to 5-gsl cans, consumption of domestic production of HDPE 1/5;
