Introduction of Plastics Engineering

Plastics Engineering means design, development, processing and manufacturing of plastic products, it encompasses plastics material and plastic machinery.

Plastics are typically organic polymers of high molecular mass, includes a wide range of moldable synthetic or semi-synthetic organic solids. Some plastics are derived from petrochemicals and some are partially natural. The vast majority of plastics are based on chains of carbon atoms alone or with oxygen, sulfur, or nitrogen as well.

Plastic Machinery is the general term for all types of machinery and devices used in the plastics processing industry.
According to the production process of plastic products, plastic machinery can be divided into four major categories of plastic compounding machinery, plastic molding machinery, plastic secondary processing machinery and plastic processing auxiliary machinery.

Accoruding to the processing technic, plastic amchinery is generally divided into injection molding machine, plastic extrusion machine, blow molding machine etc.

1. Injection Molding Machine
Plastic injection molding machine is called usually injection molding machine for short,using the injection and molding method. Plastic injection molding of thermoplastics and thermosetting plastics made from a variety of plastic products molding equipment.
2. Plastic Extrusion Machine
Plastic extruder is usually the host of plastic extrusion machine, and its follow-up equipments are called the plastic auxiliary equipments.
With about 100 years of development, plastic extruder derived from single screw to twin-screw, multi screw or no screw and other models. Plastic extruder ( the host) can match with the pipe, film, holding materials, monofilament, flat, packing tape, crowded network, plate (sheet) material, profile, granulation, cable coating and other kinds of plastic molding auxiliary equipment, composed of a variety of plastic extrusion production lines, to produce various of plastic products. Therefore, either now or in the future, plastic extrusion machine are used widely in plastics processing industry.
3, Blow Molding Machine
Plastic blow molding machine is also called blow molding machine for short. The process of blow molding has two basic steps. The blow molding process begins with melting down the plastic and forming it into a parison or preform.
