Plastic Injection Molding Explained, and how Billiards and Elephant Ivory Lead to its Invention
Basics of Injection Molding Design.. Injection molding machines, also known as presses, consist of a material hopper, an injection ram or screw-type plunger, and a heating unit. Molds are clamped to the platen of the molding machine, where plastic is injected into the mold through the sprue orifice. Presses are rated by tonnage, which is the.
