Plastic Injection Process Flowchart - Poly Vision Group

Step 4: Granular Plastic Processing. With Injection Molding, granular plastic is fed by gravity from a hopper into a heated barrel. As the granules are slowly moved forward by a screw-type plunger, the plastic is forced into a heated chamber, where it is melted. Injection speeds are usually determined by performing viscosity curves.
