In the conventional injection molding process, when the mold temperature is set low, the molding cycle can be shortened, but the sink line is likely to occur, resulting in poor appearance quality. On the contrary, when the mold temperature is set high, the appearance quality of the surface of the product can be improved, but warpage, sagging, poor size, and the like are likely to occur, and the molding cycle is prolonged, and the cost is increased.
High-gloss steam injection molding technology can solve both problems at the same time. It uses the steam and cooling water generated by the steam furnace to control the temperature of the mold during a molding cycle, so that the advantages of both methods can be exerted.
First, by injecting steam before injection, the temperature of the mold is brought to a temperature exceeding the thermal deformation of the resin, and then the molten resin is injected, thereby forming a molded article having no surface and good surface quality. After the injection of the molten resin is completed, the cooling process is started. Cooling water is used to rapidly lower the mold temperature below the temperature at which the resin is thermally deformed. In this way, the molding cycle can be shortened by speeding up the curing speed of the resin, and problems such as warpage and sagging can be solved.
High-gloss steam injection can eliminate the surface melting, splicing, corrugation and silver thread on the surface of the product, completely solve the surface shrinkage phenomenon of the plastic product, and make the surface finish of the product reach the mirror level. The product does not require subsequent processing of the spray, which effectively reduces costs and shortens delivery time. In addition, high-gloss injection molding can also solve the floating effect of fiber-added products.
