The mold comprises two main parts: the injection mold (A plate) and the ejector mold (B plate), which are also known as moulder and mouldmaker. Plastic resin is introduced into the mold via a sprue or gate in the injection mold. The sprue bushing seals tightly against the nozzle of the injection barrel of the molding machine, allowing molten plastic to flow from the barrel into the mold, known as the cavity. The sprue bushing guides the molten plastic into the cavity impressions through channels on the A and B plates. These channels, called runners, enable the plastic to flow along them. The molten plastic moves through the runner and enters specialized gates, ultimately filling the cavity geometry to create the desired part.

We accompany you with our design and development from the idea to series production! We process all common thermoplastics for you. Besides polyurethane, these are mainly: PE (polyethylene), PA (polyamide), PP (polypropylene), POM, ASA, TPU, PP, TPE as well as glass fiber reinforced plastics. Advantages of the injection molding process are low unit costs with high batch sizes. Before an injection mold is ordered, we build view samples for you as laser-sintered elements or by means of 3D printing. In this way, the desired part can already be viewed without having to spend a lot of money. Our machines inject molded parts from 5 to 6000 grams.
