Problems solved by technology

[0004] Common engineering plastic-based composite materials in the prior art are mainly materials reinforced by compounding glass fibers in engineering plastic materials. Due to the high price of glass fibers, this type of material is easy to be exposed from the surface of the product after reinforcement, which seriously affects the appearance of its products. In addition, because the uneven distribution and orientation of glass fibers has a great influence on the shrinkage rate, the product is prone to warping, and the orientation of the original design mounting hole of the mold will shift on the injection molded product, making installation quite difficult , shortened service life
In addition, engineering plastic-based composite materials on the market still have poor compatibility between different types of materials, complex preparation process, high preparation cost, and the weather resistance, wear resistance, stability and mechanical properties of materials need to be further improved Defects
