It is usually necessary to ensure that the raw materials do not contain moisture and dust and other impurities. With the progress of technology, the production process of heat conducting plastic is constantly optimized. Advanced mixing and melting technology is adopted to improve the uniformity and heat conduction efficiency of the material, promote the sustainable development of heat conducting plastic, and meet the market demand for high-performance, low-environmental impact materials.

[0003] In the production process of heat conducting plastic, the general mixing and melting device often contains moisture and dust and other impurities in the heat conducting plastic raw materials.

The presence of dust and other impurities will cause the physical properties of the material to be unstable, affecting its performance in subsequent processing, thereby reducing the product's pass rate. The occurrence of these problems makes enterprises face higher rework costs and quality risks in the production process, which cannot meet the actual demand. UTILITY MODEL CONTENT
