ESMA works to the greatest extent by injection molding of the plastic material Vespel® and polyurethane but also with machined plastics. Vespel® can be sintered, which is a big advantage over other polymers.
Advantages of plastics
When you need components with good tolerances and high requirements on function (for example, you want to avoid creaking noise), plastic components are a very good option. Plastic components are both easier and cheaper to manufacture than metal components.
Molding means that a plastic granulate is heated and injected into a mold under high pressure, then cooled down and detached from the mold. The method fits well for relatively complex components, when the requirements for dimensional accuracy or surface finish are high. Because the tool cost is relatively high, larger series need to be produced to maintain cost-effectiveness.
Injection molding is today used in many different industries, it is especially common in the furniture industry and in household and electronic products. ESMA supplies injection molded plastic components to the automotive industry. For example, you can find plastic components on the dashboard and in various panels. We often also work with entire component systems in several different materials, where a plastic component often is included.
