PASTIC MATERIAL EXTRUSION DEVICE HAVING TEMPERATURE CONTROL UNIT

摘要

PURPOSE:To eliminate temperature drop of plastic due to the contact with a core wire, to prevent the separation of plastic tailings, and to smooth the extrusion coating, by means of a temperature control unit on a core wire guide point. CONSTITUTION:The temperature control heater 15 is built in the point adapter 6 provided in the molten plastic channel 16 of the crosshead 2. The temperature control heater 15' is provided in the point holder 7, and the temperatures of the adaptor 6 and holder 7 are controlled to prevent the temperature drop of the molten plastic. EFFECT:Low friction resistance.
