Plastic & Rubber
Injection molding is a process that involves heating plastic granules and injecting them into a die to get the desired shape and size of the plastic form. Plastic in granular form is fed from the top hopper, moved to a screw conveyer, heated to a moldable temperature, and combined to form a semi-solid shape. After that, the moldable plastic is extruded and pressed against a die of the required shape.
