The concept of plastic injection molding
Plastic Injection molding is used to produce many things such as wire spools, package and bowl, bottle caps, automotive parts, toys, optics, some musical instruments (and parts of them), prototype china one-piece chairs and small tables, storage containers, mechanical parts (including gears). And most other plastic products available today. Injection molding is the most common modern method of manufacturing parts. It is ideal for producing high volumes of the same object.
The injection molding process mainly includes 6 stages, such as closing die – filling – pressure-retaining – cooling – mold opening – demoulding. These six stages directly determine the quality of the product, and these six stages are a complete continuous process. This chapter focuses on the four stages of filling, pressure retaining, cooling, and demolding. Injection molding uses a ram or screw-type plunger to force molten plastic material into a mold cavity; this solidifies into a shape that has conformed to the contour of the mold.
