Injection molding machine

An injection molding machine also known as an injection press, is a machine for manufacturing plastic products by the injection molding process. Injection molding is a method to obtain molded products by injecting plastic materials molten by heat into a mold, and then cooling and solidifying them. The method is suitable for the mass production of products with complicated shapes, and takes a large part in the area of plastic processing.

Working principle:
The molding machine heats the plastic until it is liquid. The nozzle of the injection molding machine then injects the melted plastic into the mold (injection pressure). The cavity of the mold is now filled with plastic liquid. This will then cool down to form a solid product.

A variety of parts can be made by injection molding. Examples are automotive components such as: intake manifolds, dashboard switches and knobs; medical parts such as syringes or surgical devices; appliance housings, electrical circuit boards, bottle caps, toys, jewel boxes and components of portable pottyes.
