The following analysis is made on the automotive carpet sheet extruder
A variety of products with constant cross-section and continuous length. Such as tube sheets, rods, sheets, wires, films, wires and cables, coated profiles, etc. Plastic coloring, mixing, plasticizing, granulating and blending modification, etc. Extrusion blow molding The melt or viscous fluid is continuously formed through a die of a certain shape under the extrusion of the screw or plunger of the extruder. The resulting product is a continuous product with a constant cross-sectional shape.
The basic process of extrusion molding is that the screw rotates and continuously transports the plasticized material from the extruder barrel to the die head of a certain shape so that it can be molded in a molten state. It is pulled out from the die and cooled and shaped at the same time.
The key part is the screw barrel of the extrusion system.

The feeding port is on the barrel and plays the role of feeding material. The feed port can be water-cooled to prevent premature heating of the polymer and enhance the conveying effect. The feeding part is used to transport materials to the hopper, continuously and evenly feed materials, and preheat, dry and mix.
The main parameters of the screw are the aspect ratio of the screw diameter/the ratio of the effective length and diameter of the working part of the screw, such as screw groove depth and helix angle and thread edge width. The main factor that determines the screw volume capacity affects the rate of heat transfer from the barrel wall to the material. The effective working length depends on how long the material goes through to reach the viscous flow state required for molding.
Increasing the aspect ratio, improving the temperature distribution of plastics, making mixing more uniform, reducing leakage and backflow, and improving production capacity are the development directions. Generally
but it is too big to squeeze heat-sensitive plastic, and it is difficult to manufacture and install. The selection is based on the physical properties of the material and product performance requirements.
