1.What reasons for insufficient filling, unclear outline , marginal incomplete in die casting?
Main reasons：
1、Liquidity shortage of molten aluminum, molten aluminum contains high air content, has more oxide skin.
2.Poor gating system, too small gate section.
3.Poor venting, too much coating, or too high mould temperature making air hard to vent.
Solutions：
1.Increase the liquidity of molten aluminum, appropriately increase gating temperature, mould temperature and gating speed.
2.Increase gating section acreage.
3.Improve venting conditions, add material chute and venting plug etc.

Powder coating is a dry coating process used as a metal finish. It is applied as dry powder through an electrostatic process, then cured with heat. …
Spray painting is a way of using the spray gun to use the air pressure, to generate uniform and fine fog droplets, and apply to the surface of the coated surface.
Aluminum anodizing is an electrochemical process that converts aluminum into aluminum oxide at the surface of the casting to improve the natural corrosion resistance.
