Plastic Processing
Also known as plastic molding processing. It is a general term for various processes that convert synthetic resins or plastics into plastic products. It is a large production department in the plastics industry. Plastic processing generally includes plastic batching, molding, machining, joining, modification and assembly. The last four processes are carried out after the plastic…

Plastic Modification
Plastic modification is a relatively broad concept. Whether it is to improve the original properties of the resin through physical, chemical, mechanical or other means, it is called plastic modification. The application range of plastic modification is relatively wide. Definition It can be said that all plastics can be modified to improve their quality, such…

Blow Molding
Also known as hollow blow molding, it is a rapidly developing plastic processing method. Blow molding technology began to be used to produce low-density polyethylene bottles during World War II. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely used. The…

Injection Molding
A plastic processing method in which the plastic is plasticized in the heated barrel of the injection molding machine and then injected into the cavity of a closed mold by a plunger or a reciprocating screw to form a product. This method can process products with complex shapes, precise dimensions or with inserts, and has…

Compression Molding
Compression molding (also known as press molding or compression molding) is a process in which powdered, granular or fibrous plastics are placed into a mold cavity at molding temperature, and then the mold is closed and pressurized to form and solidify it. Compression molding can be used for thermosetting plastics, thermoplastics and rubber materials. Introduction…

Extrusion Molding
Extrusion molding is also called extrusion molding in plastic processing. It is a processing method that uses hydraulic pressure on the mold itself to extrude. It refers to the action between the barrel and the screw of the extruder, while being heated and plasticized, and being pushed forward by the screw, and continuously passing through…
