The production process of Composite Wall Cladding
WPC wall cladding are composite materials made by mixing wood fibers, HDPE and other additives, the following is the general manufacturing process of WPC wall panels:
Raw Material Preparation
First, wood fibers, HDPE and other additives need to be prepared as the main raw materials.
Material Mixing
The wood fibers, HDPE and additives are fed into a mixer or extruder for mixing. In this step, by adjusting the proportion of additives and mixing time, ensure that the wood fibers, HDPE and additives are fully mixed and even.
Extrusion Molding
The mixed WPC material is extruded into a wallboard of a specific shape through an extruder. The extruder heats the material to a temperature where it becomes malleable, then squeezes it through a die to create the shape of the wallboard.
Cooling and Solidification
The extruded WPC wallboard goes through a cooling process to make it solidify and stabilize. During the extrusion process, the shape of the wall panels remains stable.
Cutting and Shaping
The extruded WPC wall panels are cut to the required length, shaped and trimmed in order to get the final wall panel product.
Surface Treatment
As required, WPC wall panels can be finished with surface treatments such as printing, embossing or painting to provide different textures and patterns.
Packaging and Shipping
Finally, the finished WPC wall panels are packed and ready to be shipped to the market or customers.
