Our machines allow to mould from very small to big Silicone parts, up to dimensions of 1 sqm. Some flexible plants are designed to produce small quantities, other machines are dedicated to significantly long productions.

We can offer Silicone in any RAL colour or transparent, and with specific features according to the final use of the part: we use high-temperature resistant Silicones (up to 300°C), electric insulator Silicones and conductive Silicones.

Plus, one of our strenghts is the ability to co-moulding rubber on metal inserts.
