Casting design reinforcement requirements:Precision casting steel is thin wall thickness change, in order to improve the strength and rigidity of the parts, prevent to reduce casting contraction deformation, and avoid the workpiece deformation during ejection from the mould and filling to function when the secondary circuit (metal flow path), the thickness of the die casting steel should be less than the thickness of the wall, generally take the place of the thickness of the 2/3 to 3/4. 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, 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.
