When setting the parameters of the extruder of WPC decking production line, the operator need to consider many factors, such asRaw material characteristics，Product specification requirements，Extruder performance etc
As an important processing equipment, wood-plastic extruder can process wood-plastic materials into products of various shapes and specifications, and is widely used in construction, furniture, packaging and other fields. Below, Yongte will introduce in detail how to operate the wood plastic extruder.
WPC foam board, also known as wood-plastic composite foam board, is a new type of environmentally friendly building material. It uses wood powder, plastic, etc. as the main raw materials, and is made by adding an appropriate amount of foaming agent and other additives through mixing, extrusion, foaming, molding and other processes. Wood-plastic foam board has the dual advantages of wood and plastic.
The single-screw extruder is mainly composed of a feeding device, a screw, a barrel, a machine head, a cooling device and a driving device. Its working principle is that the motor drives the screw to rotate in the barrel, so that the material is transported forward under the friction between the screw and the barrel.
The parallel twin-screw extruder consists of two screws arranged in parallel, forming a long and narrow material channel between them. When the material is fed into the extruder, the two screws rotate and mesh with each other to push the material forward and gradually compress it. In this process, the material is subjected to various effects such as shearing, mixing and heating, thereby achieving plasticization and melting.
the conical twin-screw extruder is based on the melting and extrusion of plastic under the rotation and pushing action of the screw. When the raw materials are fed into the hopper of the conical twin-screw extruder, they are sheared, mixed and melted by the screw to form a uniform melt. As the screw rotates and pushes, the melt is transported to the die of the machine head and finally extruded.
