Title:
LOW PRESSURE EXTRUDER, EQUIPMENT AND METHOD FOR MANUFACTURING A LOW-DENSITY PLASTIC COMPOSITE MATERIAL, AND THE LOW-DENSITY PLASTIC COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2022/107015
Kind Code:
A1
Abstract:
The invention relates to a low pressure extruder (3) for manufacturing a low density plastic composite material, characterized in that, the volume between the cylinder and the screw per unit length is not decreased along the direction from the hopper to the die in order that the mixture is extruded at low pressure in the melted state out of the cylinder of the extruder; the die is heated by the heater to maintain the melted state of the material in order not to create resistance to the flow in the process of pushing the material mixture out of the cylinder of the extruder. Furthermore, the present invention provides a method and equipment for manufacturing this material.
