Solid rods can be manufactured using special pressing and sintering technologies. The semi-finished products are manufactured with respective allowances. These allowances are set such that as little waste as possible is pro-duced during machining while at the same time ensuring that the finished part contour can be manufactured without problems. PTFE CC GmbH has a narrowly graded tools park to achieve an optimal ratio between the dimensions of the semi-finished product and that of the finished component. Due to the varying material-related shrinkage that occurs (there are marked differences between pure PTFE, modified PTFE and PTFE compounds), slight variances in the dimensions of the semi-finished products are possible even when working with the same tool dimensions. For this reason, we do not work with semi-finished listings, but adapt the dimensions of the semi-finished product to your finished product dimensions.
