Rubber injection moulding
The right choice of rubber material
The choice between TPR, TPU and other rubber materials depends on the part's desired requirements for temperature resistance, chemical exposure, mechanical stress and expected service life. With extensive experience in both TPR injection moulding and TPU injection moulding, we can analyse the desired functional requirements at an early stage. We guide our customers early in the development process to a material choice that balances function, quality and cost.

Durable rubber details
Rubber injection moulding has different requirements than traditional plastics production, where the elastic properties of the material must be controlled as carefully as the geometry. Our production is optimised for components subject to repeated movement, vibration or friction, where even material distribution and stable elasticity are crucial. Through automated handling and consistent process monitoring, we ensure that each rubber component fulfils defined functional requirements. The result is durable and functionally reliable rubber parts adapted for technically demanding applications.

The choice between TPR and TPU depends on the functional requirements of the application. TPR is often used when flexibility and cost-effective production are prioritised, while TPU is better suited for wear-prone components where high abrasion and tear resistance is required.
Injection moulding of rubber is suitable for both medium and large series where repeatable quality and consistent performance are important. The process provides good control of tolerances and material properties even in longer production runs.
Yes, rubber components can be overmoulded or combined with other materials to create integrated features such as grip, sealing or vibration damping.
