Know-how regarding the construction of molding tools is just as important as experience in handling the material to be processed: following vulcanization, complex three-dimensional structures have to be removed from the tool without any overstretching. Rubber articles that fill up the entire hollow area of the mold at high temperatures shrink in varying extents when they cool.
When developing these tools, the Grahneis GmbH does not just simply use computer-assisted construction methods. Rather it is their knowledge that is the key: knowledge regarding shrink factors, chemical, thermal and numerous other properties. It is this specific combination of the latest technology and years of experience that yields optimal construction results. And thus providing articles that meet the very highest requirements.
