PCTFE / PTFCE extrusion DEMGY SPN has developed the extrusion of PCTFE (or PTFCE / KEL-F / Voltalef), a plastic material suitable for cryogenic applications. The extrusion process continuously transforms this material and allows longer bar lengths with a homogeneous process. The bars can therefore be produced for a diameter...
Plastic turning DEMGY SPN is equipped with numerous high-performance machine tools for its machining operations. For the turning of plastic components, our team uses digital lathes (MAZAK and MORI SEKI) and conventional lathes (Cazeneuve) to machine these components according to customer specifications. The turning operation consists in machining plastic parts which...
Plastic compression molding DEMGY SPN produces plastic compression moulding to manufacture blanks (semi-finished products). This process is based on the shaping, the heating and the compression of plastic materials. Compression can be at high temperature as for PCTFE (PTFCE / Voltalef / KEL-F) or standard temperature as for PTFE (charged...
