Advantages of High Light Speed Cold Speed Hot Mold Thermostat

        In high-gloss injection molding, the most critical factor is the mold, material, and mold temperature control machine, referred to as a mold temperature control machine. In ordinary injection molding processes, setting the mold temperature low can shorten the molding cycle, but it is easy to generate convergence lines, resulting in poor appearance quality. On the contrary, when the mold temperature is set high, it can improve the appearance quality of the product surface, but it is prone to warping, sinking, poor size, etc., while extending the molding cycle and increasing costs.

        High gloss steam injection molding technology can solve both of the above problems. It uses 180 degrees of superheated water and cooling water to control the temperature of the mold within a molding cycle, thereby giving full play to the advantages of both methods.

        High gloss steam injection molding uses high-temperature steam to create a uniform heating path on the mold (similar to the cooling path of ordinary molds). When the injection molding machine closes the mold, it blows in high-temperature steam, first increasing the mold temperature to a set value, and then starting to inject plastic into the mold cavity. After the injection molding machine completes pressure maintaining and turns to cooling, it starts to inject cold water, and the mold temperature quickly drops to a set value before opening the mold, Then blow air into the mold to completely blow away the cold water, completing the entire injection molding process.

        Firstly, before injection, hot water is sprayed to make the temperature of the mold reach a temperature that exceeds the thermal deformation of the resin. Then, molten resin is injected to form a molded product with good surface quality and no converging lines. After the injection of the molten resin is completed, the cooling process begins. Use cooling water to rapidly reduce the mold temperature below the temperature of the resin during thermal deformation. In this way, it is possible to shorten the molding cycle and solve problems such as warpage and sagging by accelerating the curing speed of the resin.

        High gloss steam injection molding machine can eliminate product surface welding lines, welding marks, ripples, and silver threads, completely solve the surface shrinkage phenomenon of plastic products, and make the surface smoothness of the product reach mirror level. The subsequent processing of the product does not require spraying, effectively reducing costs and shortening delivery time. In addition, high gloss injection molding can also solve the floating fiber phenomenon caused by fiber reinforced products, thereby making product quality more perfect. In thin-wall molding, high gloss injection molding helps to improve injection molding fluidity and improve product quality and strength. It can also reduce the injection molding cycle of thick wall molding by more than 70%.
