  • Plastic Extrusion vs. Injection Molding - Engineered

    2016-3-18 · Injection molding forms three-dimensional shapes. The injection molding process was first established in the 1930s. The thermoplastic extrusion process was fully developed in 1935. Extrusion is a method using molten plastic or many other materials that are pushed through a two-dimensional die opening. In both processes , the scrap can be recycled reducing waste. The injection molding process is based on the molten die-casting method.
