Thermoplastic forming units designed to manufacture dental plastic products with high dimensional precision using injection procedures. Typical injection molding machines consist of a heated barrel with a reciprocating screw driven by a motor. The motor feeds molten polymer (e.g., nylon, polypropylene) in a temperature-controlled split mold conformed in the shape of the final product. The product is ejected from the machine mold after the process is finished. Injection thermoplastic units are used in dental laboratories to produce a variety of plastic (e.g., resin) products, including denture bases.
