Plastic Injection Molding

The concept of plastic injection molding

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

Plastic Injection molding is used to produce many things such as storage containers, bottle caps, automotive parts, toys, optics, some musical instruments (and parts of them), one-piece chairs and small tables, 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.
