Precision casting in the design of the casting when we want to design all conform to the business of casting and so on the circulation on the market more widely, so we in the design of the casting we should according to the requirements of casting some kind to design the casting precision casting?Precision casting design rounded requirements:Precision casting die casting on every wall and wall connection, regardless of right Angle, acute or obtuse, the root of the blind holes and grooves, should be designed with rounded corners, only when is expected to determine the parting surface position, do not use the rounded connection, the rest parts generally must be rounded, rounded shoulds not be too big or too small, too small die casting cracks easily, too easy to loose shrinkage cavity, die casting round generally take: 1/2 wall thickness R or less wall thickness or less;The rounded's role is to help the flow of metal, reduce the eddy current or turbulence;Avoid to some parts with rounded corners on the stress concentration caused by cracking;When the parts to be plating or coatingDesign all kinds of in line with the business of casting, so on the circulation on the market more widely, pay attention to the rounded corners, shape, structure, design of precision casting wall thickness and reinforcement details such as requirements, to design and produce a better quality of precision castings.
