Technical Essence: The Molecular Revolution of Elasticity and Environmental ProtectionTPU (Thermoplastic Polyurethane) film is a high-performance material realized through molecular design of polyester/polyether segments and isocyanates. Its core value lies in integrating the elasticity of rubber wi

First, heat the extruder to the predetermined temperature, then start the screw and feed materials simultaneously. Extrusion molding is a continuous process, with the key being the adjustment of initial extrusion parameters. It is necessary to adjust process parameters such as the temperature of each heating zone in the extruder barrel, the temperature of the die head, and the screw rotation speed according to the extrusion process properties of the plastic and the structural characteristics of the extruder die head, so as to control the temperature and pressure distribution of the material within the barrel. According to the requirements for the shape and dimensions of the product, adjust the die size, concentricity, traction equipment, and other devices to control the exit swelling and shape stability of the extrudate, thereby ultimately controlling the output and quality of the extrudate until the extrusion reaches normal operation for continuous production.
