What is plastic injection molding?
Injection molding is a part manufacturing process by injecting material into a closed mold. Injection molding can include a wide variety of materials, including metals, glass, and in some cases, thermoset elastomers and polymers. The parts to be injection molded should be designed to facilitate the molding process.
The material used for the part, the desired shape and characteristics of the part, the material and the design of the mold, as well as the properties of the molding machine must be taken into account. It is essential to consider the quantity of parts required and the useful life of the tools. This is because injection tools and presses are more complex and therefore more expensive to install and use than other molding techniques. Therefore, small batches of parts may not be profitable if manufactured by injection molding.
