Problems solved by technology

This technical solution adopts the form of setting a heater on the screw, and the raw materials are melted and heated during extrusion and drawing. The whole process cannot guarantee uniform heating, and for some plastic materials with high melting temperature, it cannot meet the production needs. In order to ensure the melting of raw materials in the process, high-speed operation cannot be realized, and the production efficiency is low
