Silicone Extrusion

Key competences

Silicone extrusion is a specialized manufacturing process where high-quality silicone materials are precisely shaped into custom profiles, seals, and components. Any 2D geometry of your choice is possible with a low investment cost and short lead times.

Expertise

Co-extrusion: Co-extrusion of different colors, as well as hardnesses are possible without the risk of bleeding between materials and colors!

Sponge Silicone: Sponge silicone offers flexible solutions for a wide range of applications with its reduced density and low compressive force.
