Micro-foaming technology of wood plastic composite grape racks continues to advance

Although wood plastic composite grape trusses have many advantages, the greater density is its biggest disadvantage, which limits its application range. In order to reduce the density of wood plastic composite materials without reducing the physical and mechanical properties of the composite materials, the requirements of light weight and high strength are put forward for wood plastic composite materials.

In recent years, wood plastic composite micro-foaming technology has also been greatly developed, especially for PVC-based manufacturers. In order to meet product performance requirements, it is necessary to develop new processing techniques, introduce foaming technology, reduce material costs, and expand wood plastic composite range of use.

After foaming, the wood plastic composite material not only reduces the density, but also improves some of the physical and mechanical properties, so that it can be used as the light and high-strength parts required by the automotive industry, sports equipment, packaging, and construction industries.

Molding process technology tends to be differentiated
My country's wood plastic composite materials started with the extrusion molding process. After years of development, product homogeneity has been formed, resulting in fierce price competition and affecting the healthy development of the industry. In fact, wood plastic composite materials can be understood as modified plastics that use biomass fibers as modifiers. Therefore, other plastic molding methods can be used. Different molding processes can be used to produce different types of products, such as injection molding. It can produce various three-dimensional products such as vehicle parts, toys and daily necessities. At present, some domestic enterprises have begun to develop in the direction of differentiation of plastic wood products.

Application of surface modification technology
In order to improve the usability and surface aesthetics of wood plastic composite products, post-treatment of the surface of wood plastic composite products is also indispensable. At present, surface post-treatment technologies mainly include: belt sanding treatment, embossing treatment, water transfer and thermal transfer, UV printing and solid wood leather composite. These technologies have been successfully applied to the surface post-treatment of wood plastic composite materials, greatly improving their aesthetics and added value.
