Importance of Die Casting Mold Design
Mold design affects the uniformity of a product, configuration, shape and quality created through the die casting procedure. If not specified properly it can result in tool or material corrosion, as well as inferior product quality, while efficiency and production time can be improved by an effective design.
Factors that Contribute In Quality Die Casting Mold Design
While deciding on the appropriate specifications for a project there are a number of mold design factors to consider. Three major of these factors include:
Fillets
To smooth an angled surface a fillet is a concave junction that is used. The casting process gets hindered by the sharp corners, so to create rounded edges many molds have fillets and reduce the risk of production errors. With the exception of the parting line, fillets from zinc die casting mould manufacturer can be added nearly anywhere on a mold.
Parting Line
Different sections of the mold together are connected by the parting line, or parting surface. From work strain if the parting line is imprecisely positioned or becomes deformed, through the gap between the mold pieces material may get seep, leading to non-uniform molding and excessive seaming.
Draft
Draft is the degree to which a core of a zinc die casting mould china can be tapered. To smoothly eject the casting from the die a precise draft is required, but features such as depth of the mold, the type of molten alloy used, and shape of the wall, can affect the process as the draft is not constant and varies according to the angle of the wall. In general, due to the risk of shrinkage untapped holes require tapering. Similarly, inner walls require more drafting than outer walls as they can also shrink. Follow us on Facebook
