         aluminum made mold used for automotive industrial application this category of mold already has very more year history, already in automotive industry outer enterprise in 流行起.

        但 how to long this mold use lifespan, make its can suitable for has production?如今 non electroplating spray coating process is most is commonly used.

         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. 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.

         non electroplating coating uniform in mold has surface upper, therefore it will comprehensive cover/cap parts, has 螺纹孔 and 销钉孔 and other, this upper improve/increase aluminum made mold structure property. another non electroplating coating application will effect/influence aluminum features, is it is in 180℃ low temperature conditions lower application.

         water can from aluminum made mold non electroplating coating in 获益. if use has necessary has water shrinkage or white similar 于鳞状 coating, it can reduce processing cycle, is electroplating material upper can remove this issues.

         aluminum has different and other grade, need using/adopting different methods, ensure its for electroplating material has 适当附 force.

         future injection molding production aluminum made mold use trend will 会持续 lower, 无疑也 will development series more new aluminum alloy material, 以适应 and meet/satisfy different mold production and application demand, 而我们也会找出 more good long aluminum made mold use lifespan methods.
