         due to new technology and aluminum made sheet/plate development, especially is is injection molding design, aluminum made mold 也越 越普遍 used for blow molding 模, R.I.M.模, 橡胶模, structure foaming and R.T.M.模 and other field/area. tube/pipe it can can combined has application areas, 但事实 upper, its use 变 越 越普遍. 每 人都希望 can long mold production use lifespan, using/adopting 传统 工 tool manufacturing mold, its surface using/adopting hard or metal electroplating, or using/adopting more is 专业化 engineering coating material, this can anti its surface abrasion loss or 腐蚀, make its more good demolding. rear, is 寻求同样 target/goal, using/adopting aluminum made mold, to combined solutions.

         is can injection molding production decoration property relatively good parts, remove long mold use lifespan outer, manufacturing also aluminum made mold surface can maintain 一定程 degree gloss degree, therefore using/adopting non electroplating spray coating process, is this type of methods has 助于延 long mold surface light degree lifespan, make its production decoration property parts versus comparison relatively easy.

         due to aluminum 材 质 relatively soft, if using/adopting surface coating, easy by plastics abrasion loss, accelerated its loss bad degree, from 而改变 injection molding parts gloss degree. non electroplating coating can make mold surface increase 50RC, make its 足以保护 and long mold surface gloss degree and structure. non electroplating coating can ratio aluminum 材本身 obtain more good surface light degree quality, must is, in mold can electroplating front, need 进行一 surface treatment. 例如, is make its can to grade quality water 平, 建议首先 will aluminum made mold surface processing to SPIA-3 grade light degree water 平, rear in its 进一步抛 light front, again application 0.0003~0.0005 high non electroplating coating, make its to grade quality light degree water 平.
