Casting rounded corners

The intersection of various parts of the die casting should have rounded corners (except for the parting surface) to ensure smooth metal flow during filling, easy gas discharge, and to avoid cracks caused by sharp corners. For die castings that require electroplating and coating, the rounded corners can be evenly coated to prevent coating buildup at sharp corners. The fillet radius R of die castings should generally not be less than 1mm, with a minimum fillet radius of 0.5 mm.The fillet radius R of castings should generally not be less than 1mm, and the minimum fillet radius is 0.5 mm.

All wall to wall connections on die castings, regardless of right angles, acute or obtuse angles, blind holes, and the root of grooves, should be designed as rounded corners. Only when it is expected to be determined as the parting surface, rounded corners should not be used. The rest of the parts must generally be rounded corners, and the rounded corners should not be too large or too small. If they are too small, die castings are prone to cracks, and if they are too large, they are prone to porosity and shrinkage. The rounded corners of die castings are generally taken as 1/2 wall thickness ≤ R ≤ wall thickness. The function of rounded corners is to facilitate the flow of metal, reducing eddy currents or turbulence; Avoid stress concentration and cracking on parts due to the presence of rounded corners; When parts are to be electroplated or coated, rounded corners can obtain a uniform coating to prevent deposition at sharp corners; It can extend the service life of the die-casting mold and prevent corner collapse or cracking due to the presence of sharp corners in the mold cavity. Rounded corners can ensure smooth flow of molten metal, improve mold filling retention, and facilitate gas discharge. At the same time, avoid stress concentration caused by sharp corners, which can lead to crack defects. Especially when die-casting parts require electroplating treatment, rounded corners are essential to ensure their good electroplating effect.
