What is the development trend of plastic-wood composite products?
In terms of molding process, the extrusion molding process is the mainstream method of molding and processing of plastic-wood composite products, and is mainly used for developing profiles, pipes and plates. With the diversification of plastic wood products, such as plastic-wood multi-layer composite pipe and plastic wood micro-foaming floor, higher requirements are put forward on the extrusion process, and its research and development direction is multi-layer plastic-wood composite co-extrusion and coating. Extrusion, coextrusion of steel/plastic wood, coextrusion of plastic/plastic wood, etc. Injection molding is mainly used for plastic wood parts and auto parts, etc. Its new development trend is large-scale product development and engineering plastics, such as ABS plastic wood products.
The molding method and process are the new trends in the development of plastic-wood composite products, such as multi-layer multi-station intermittent, hot extrusion cold pressing and continuous rolling, especially the development of large-scale plastic wood products such as wide-width thick-walled plates. The molding process can greatly improve work efficiency, reduce production costs, and produce products that are difficult to achieve by other methods.
