Steam highlightsnon-mark technology, also known as the cold or hot plastic injectiontechnology, this technology can make the injection molding product surfacewithout weld mark and flow mark, no flow, no shrinkage mark, surface gloss tomirror effect, and the product does not need to spray the subsequentprocessing, effectively reduce the cost, shorten the time of delivery. Inaddition, steam specular injection can solve with fiber product produced by thefloating fiber phenomenon, so that product quality more perfect; In thin wallmolding, injection in high temperature melting resin to improve injection ofliquidity, reduce the injection pressure, avoid misrun and trapped gas problem,improve product quality and strength; At the same time it also can lower thethick wall injection molding cycle, about 60 ~ 70%.

Division I in 2006, has been applied the technology of steam highlightsnon-mark, developed thousands of sets of steam highlights mould, andaccumulated rich experience. The promotion to the application of the productsare: TV products after the first shell, shell, base, decoration, etc.; Airconditioning in the panel, decoration, etc.; Car inner decoration gauges in thecover, the central control panel, column B, etc.; And the application oftechnology to the transparent products, improve product quality. The othercompany through technical innovation, combined the technology of steamhighlights non-trace with double color, double color mould develop steamhighlight, successful application in air conditioning highlights double colorpalette, 26 inches and 55 inches high double color TV front shell.

Traditional mold to produce a product appearance parts difficult toeliminate surface shrink, weld marks and defects such as surface finish is notenough, not beautiful effect, and the parts requirements after spray light oiland other secondary surface processing, production cycle and the manufacturingcost caused great waste; According to the present situation of our products,high-grade product scrap rate is high, easy scratches on the surface of theinjection, the phenomenon such as expensive, comprehensive described above inorder to meet customer requirements, improve product quality, improveproduction efficiency, the fuselage parts mould made highlights non-mark mould,the technology on the improvement of our injection molding technology hasfar-reaching significance.
