Study and application of high-gloss & no-weldline steam injection molding technology

The high-gloss ＆ no-weldline steam injection molding technology has been increasingly applied in China. Its technical principle and realization method were introduced. The working process and manufacturing devices of this technology were described in particular. Some key technologies were researched, such as the prevention of the mold crack from thermal fatigue, the optimization design of the heating and cooling channels and the fine mirror polishing technique. Through this technology, fine product surface quality was acquired which featured high-gloss, no weld-line, no flow mark, no flow line and mirror effect. Meanwhile, the part＇s strength and surface hardness were also improved.
