        Product Details

        Specializes in the design of the casting people know, the wall thickness of the stainless steel castings casting quality has a great influence, casting thick walls, the walls were too thin is not good, so in the design of die casting design wall thickness should be reasonable force Paul casting quality is not affected by the thickness aspect from.
        In aluminum die casting, for example, under normal circumstances, have higher strength and thin wall better than the thick dense casting, in view of this, stainless steel castings design should follow this principle: to ensure sufficient strength castings and rigid premise should be to minimize the thickness and maintain uniformity in wall thickness. Practice has proved that the wall thickness of casting design generally 2.5-4mm appropriate, the wall thickness of the part should not be used more than 6mm die-casting production process.
        Casting wall is too thick, thin wall castings quality performance effects: If the design of the casting wall is too thin, make good metal welding, casting a direct impact strength, while forming would cause difficulties; the walls are too thick or severe uneven prone deflated and cracks, on the other hand, with the increase in wall thickness, casting internal porosity, shrinkage and other defects also increase, it will also reduce the casting strength, influence casting quality.
