Analysis of Packaging Force against The Core in Die Casting

The packaging force will applied to the core during solidification stage of die casting due to alloy shrinkage.The castings still shrink at room temperature after getting off mould.The shrinkage rate is 0.4%-0.7% for die casting.This shrinkage range make designer feel hard to choose during tooling design. The packaging force is subject to draft,roughness,ejector pins layout,release agent quality,mould temperature and casting temperature.Cangzhou Weiheng Metal Products Co.,Ltd Professional Die Casting Supplier. die casting parts Thermal expansivity of tooling steel and casting alloy are [...]

Anodizing for Different Die Casting Aluminum Alloy

Composition of alloy play negative effect on anodizing.At same condition,Pure aluminum can achieve best finishing of anodizing.To get best anodized aluminum,the composition of aluminum can not be lower than 95%.Weiheng Die Casting can provide anodizing service for die casting parts. die casting aluminum alloy Among elements of alloy,copper can make anodizing become red and increase defects of oxide.Silicon will turn anodizing into gray and finishing become worse when composition of silicon over 4.5%.Iron will turn into black after anodizing. Die casting aluminum [...]
