How to Do China Aluminium Die Casting Moldmaking

Die casting and the use of an aluminium mold for plastic injection contributes majority to the production of a large number of metal parts and components. Moldmaking or the incorporation of an aluminium mold plays a major part in giving shape and structure of the final product. The die casting process forces the molten metal into molds and hence requires a mold with an exact specification in order to achieve the desired product in accurate size. The use of an Aluminium mold for plastic injection process has already made a huge success in achieving the target of manufacturing the plastic parts and components according to the client's requirement with accuracy. So, in this blog let's just discuss what are those factors which can affect China Aluminium Die Casting Moldmaking.


Draft is the degree to which the mold can be tapered. For ejecting the casting from the die, a precise and accurate draft is needed for smoothing the process, but this doesn't hold true always as draft is not constant and varies according to the angle of the wall that can play a major role in China aluminum die casting moldmaking. Mold geometry can be less influential on draft. Similarly inner walls can also shrink and require more drafting than outer walls.


During moldmaking there occurs angled and sharp surfaces which can be smoothened by fillets that have a concave junction which can support these angled surfaces. If there are many sharp corners arises during casting then they can be a hindrance for the molds and can increase the risk of production errors, that's why many molds use fillets to have rounded edges.

Parting Line

To connect different sections of mold, parting line is used. If the parting line becomes dispositions or attains deformity because of a lot of strain then the material can come out through the gap between the mold pieces and can lead to bad moldmaking and wastage of material.

These are some of the most important factors while doing moldmaking but there are some other similar factors which should also be taken good care of while moldmaking process.
