Injection molding is one of the most widely used methods in plastic processing. This method

applies to all Thermoplastic and parts of the thermosetting polymer, and the number of

finished products is much larger than other conventional metal forming methods. Because

the injection molding processing not only has more output, but also is suitable for many

kinds of raw materials, can produce in batches and continuously, and has stable size, It is

easy to realize the automation and high speed of production, has very high economic benefit.

The basic process of injection molding is: Plastic through the injection molding machine

screw extrusion and heating, into a molten state can flow of melt. Driven by the screw, the

plastic melt passes through the nozzle of the injection molding machine, the main channel of

the mold, the branch channel and the gate into the mold cavity, forming the products with a

certain shape and size. The result of injection molding is the production of plastic products

that meet the user’s requirements.

To obtain qualified products, must have a reasonable design, well-made mold, but also need

and the mold supporting advanced injection equipment (injection molding machine) and

reasonable processing technology. Therefore, people often call the mold, the injection

molding machine and the technology as the three basic elements that the injection molding

process can carry on smoothly.
