In many technical systems, the highest demands are placed on the individual components installed with regard to reliable sealing. In addition, the assembly process of individual components is often difficult, as conventional flat gaskets or profile gaskets cannot be installed due to the lack of space. For this reason, we offer the possibility of vulcanising the seals directly onto metal lids or housings using a tool in the injection moulding process. Thus the gasket is directly connected to the metal component and offers the following advantages, especially compared to freely applied gaskets:
- precise seal cross section
- profiled sealing cross sections with lips possible
- constant cross section over the entire seal length
- no butt joint and therefore better sealing
- Connections without adhesive application possible
In roll coating, metal cores are coated with a rubber layer, thus enabling a combination of both material properties. During production, the unvulcanised rubber is either wound onto the metal core or applied in a compression or injection mould to vulcanise it afterwards. The range is supplemented by roll cover hoses, which are already vulcanized and then wound under pretension onto the metal core.
We also offer covers made of already vulcanized rubber sheets, which are glued to the metal core with special adhesive. In many cases, roller covers are exposed to several stresses at the same time. This is why special experience is required to determine the cover quality, the design of the core and the surface quality. We have decades of experience in this field.
