We all know that WPC Embossed Board brings a lot of convenience to our production and life, so what is the molding type of wood-plastic composite material? Next, let us take a look.

Here is that the content list:

• Extrusion molding method

• Hot-press molding

Extrusion molding method

It is mainly formed by improving the molding process of traditional plastic raw materials. Similar to the application of plastic raw materials, WPC Embossed Board material needs to use professional extrusion equipment to complete the extrusion molding method. Under normal circumstances, extrusion molding can be directly applied to the extruder equipment of plastic raw materials. If necessary, the extruder can be improved according to the specific requirements of the material output to meet the WPC Embossed Board. Requirements for extrusion molding of composite materials. At present, common extrusion equipment can be divided into single screw extruder, twin-screw extruder, conical screw extruder, etc. according to the difference between the screws of its core structure. The operation process is to pulverize the basic raw materials of WPC Embossed Board composite materials, namely wood and plastic raw materials, to pellets and transport them to the inlet of the extruder. Through the heat fusion and processing of the extrusion equipment, the two raw materials are mixed and extruded. Finally, the final production of the composite material is completed by cooling and forming. The extrusion molding method of the WPC Embossed Board can realize the continuous execution of the extrusion operation. It has certain advantages in the production efficiency of raw materials. However, the key point of control in the application process is to do a good job in the two indicators of temperature and extrusion pressure. In the application of the extrusion molding method, the operation must be carried out in strict accordance with the standardized operation process.

Hot-press molding

Mainly learn from the forming process of density board. The molding principle of the WPC Embossed Board is to use pressure to intervene and promote the tightness of the mixing of two raw materials. Then, through the effect of temperature, the moisture contained in the WPC Embossing Board raw material itself can quickly evaporate, and finally, the material is formed. However, it should be emphasized that in the process of hot pressing, some special materials need to be bonded. The agent is added after mixing under pressure in the first step to promote the adhesion between the raw materials. The key points of the operation control of this molding method are that, first of all, the pressure of the hot pressing must be controlled, secondly, the temperature of the hot-pressing operation must be controlled, and finally, the time. These three elements are affected by the type of adhesive, the amount of use, the mixing ratio of wood and plastic, and the strength and thickness of the board to be made. Therefore, when using the hot-pressing method, the operation technician should fully consider and summarize the specific conditions of these influencing factors, and then adjust and standardize the hot-pressing operation process. The WPC Embossed Board composite material produced by the hot press molding method is mostly used in automotive interiors and vehicle cockpit panels in the WPC Embossing Board design of industrial products.
