Aluminum Die Casting Mounting Bracket

Aluminum Die Casting Mounting Bracket, this part carried die casting standard of Grade GB-CT4, the part has small wall thickness, meanwhile, the part have structure of big cavity, which usually easily cause problem of mold sticking, pull mark etc. The small wall thickness means the part probably happen to deform during production, which will cause actual application issue. What's more, the part surface area is big, but the thickness is small, in this situation, the far end from the location of injection, the melting aluminum will have risk of solid earlier than expected, it will cause short casting at the far end of the part, then while the part is cooled to indoor temperature, the part will have shrinkage porosity inside.  The part has requirement of surface finish of E-Coating, which has process of curing in hot thermal oven, the temperature usually be up to 170-200 degree, the porosity mentioned above will expand and get out from the part, result in pits and bubbl…
