Title: Shaping of thermoplastic components - using a blank which is moved to forming operation while still hot
Inventor: HENTSCHEL MARTIN
IPC: B29C65/02
Filed: 1992-01-20
Abstract: A component is made from a thermoplastic composite by producing a blank and letting it reach a temp. where it is sufficiently rigid to be transported. The blank is then pressed into shape before cooling. The pressing operation can be internal or external and use a mechanical tool or a fluid. It can involve a surface compaction, perforation, drawing, bending, rolling or the incorporation of inserts. A cylindrical blank (1) of thermoplastic material, such as polyethylene, is extruded and allowed to cool to a paste consistency, when it is rigid enough to be transported. The interior of the blank can still be molten. The blank is moved to a press without cooling further and a final component (2) is produced and allowed to cool until it is rigid. The second operation can also be stretching, bending, perforating or surface rolling. Reinforcing structures or metal inserts can also be placed in position. USE/ADVANTAGE - Avoids reheating the blank before the shaping operation.
