Ps foam sheet extrusion machine
working process
machine description
The production line adopts dual screw foam sheet extrusion technique.The raw material is general polystyrene granule.This equipment adopts high speed non-stop draulic filter changer and PLC controller,it is easy for operation。It has stable performance, big capacity, high automation and high quality products.
It is used widely in the packing of food, fruit, electronic product, daily necessities, hardware product, advertisement plate, etc.such as fast food box, plate,t tray,cake tray,foam tray etc.
Screw
The screw is the heart of the extruder .The material is 38CrMoAlA, which has good heat resistance and corrosion resistance, high fatigue strength , high temperature working temperature can reach 500 degrees，The outer layer of the screw is plated with alloy, which makes the hardness higher and the service life longer.
Feeding system
Metal material barrel, The length is 15~30 times of its diameter, so that the raw material can be fully heated and plasticized uniformly. ensure the efficient use of raw materials.
Cooling System
Hollowness water circulation cooling and shaping drum One set (The size will be according to customer’s requirements)
