[0002] Plastic forming uses high-pressure compaction to tightly bind plastic particles, resulting in high-density, low-porosity products. This significantly improves mechanical strength, reduces internal stress, lowers the risk of product warping and deformation, and better preserves the original properties of plastics. It demonstrates strong competitiveness in fields such as high-performance plastic processing, difficult-to-process material handling, green manufacturing, and customized production.

[0003] Currently, traditional single-screw plastic forming devices have poor mixing effects on high-viscosity plastics, which easily leads to uneven melt temperature and uneven filler dispersion, affecting the mechanical properties of the product. Moreover, the extruder die head structure in the plastic forming device is fixed, and the entire device needs to be replaced to produce plastic particles with different cross-sectional shapes, which is costly. When changing the die, the bolts need to be manually removed, which is time-consuming and affects the production efficiency of plastic particles. Therefore, there is a need to provide a plastic forming device for plastic particles to solve the above problems. Utility Model Content
