We deliver rods made from PTFE and other high performance plastics materials 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. During a process called RAM extrusion, a periodically moving punch presses the PTFE powder batchwise through a heated tube. The pressing force required for the compression is realized by wall friction or, additionally, by a brake. Several heat zones along the extrusion tube and a special temperature profile ensure that the PTFE rod is sintered through fully. The design is generally determined by the shape of the extrusion cylinder. Using RAM extrusion, rod-shaped solid rods can be manufactured quasi-continuously and economically. Please note that only standard mate-rials such as pure PTFE, PTFE/glass fiber or PTFE/carbon are extrudable. The standard lengths are 1 m to 2 m.
