Industrial seals

for all types of sealing

In our Gasket Division, we have specially equipped production lines to produce custom-made parts in addition to mass-produced parts (compression or injection moulding). We use the best elastomers on the world market, efficiently solve various technical seal problems, and guarantee fast delivery. We are among the first to have introduced liquid silicone technology to the moulding market, which allows us to offer extremely flexible machining.
