Examples of Injection-Moulded Components
Polymers and Elastomers Used in Manufacturing
We process a wide range of virgin and recycled thermoplastic materials, including PP, PE, HDPE, ABS, PA, PS, PC and POM, as well as modified and filled engineering plastics with a broad range of performance characteristics. We also have extensive experience in processing thermoplastic elastomers, including TPE, SBS, SEBS, TPV and TPU.
We work with a carefully selected network of material suppliers offering proven engineering-grade materials developed for specific applications, where requirements are defined in accordance with EN, DIN, ISO and ASTM standards or tailored to the individual needs of each customer and product.
Chemical resistance, temperature resistance, ageing performance, flame retardancy, drinking water and food-contact approvals, mechanical strength and impact resistance are just some of the parameters we consider when selecting the optimum material for your application.
Comparison of the Properties of the Most Common Engineering Plastics
Engineering plastics used in injection moulding differ not only in their mechanical properties, but also in chemical resistance, dimensional stability and performance at elevated temperatures. Selecting the right material is essential for ensuring the durability, functionality and cost-effectiveness of the finished component.
