Modern injection moulding extruder for micro-engineering e.g. optoelectronic components, etc.

摘要

The extruder unit plasticises and injects thermoplastic melt into an injection mould, especially in small quantities. It includes an cylinder (1) for the plasticising- and injection screw (2), the latter being driven in rotation and translation. The improvement centres on the heated (4) supply unit (3) melting-together (4) and delivering (5) the plastic being processed, into the cylinder.
