To deburr Die Castings for Faucet Hardware, appropriate methods should be selected based on production volume, precision requirements, and base material characteristics. For small-batch production or fine parts (e.g., around valve core holes), manual deburring is generally used—fine sandpaper or files are used for gentle grinding to remove burrs, but care must be taken not to scratch the sealing surfaces. For mass production, mechanical methods are usually adopted, such as vibratory finishing (using grinding stones and abrasives, suitable for removing burrs on surfaces and edges) and sandblasting (using high-pressure jets of fine sand to remove burrs while optimizing surface roughness). For burrs in complex holes or deep cavities, electrochemical deburring is applicable. It is important to ensure that burrs are completely removed; otherwise, issues like jamming during assembly or sealing leakage may occur. For aluminum alloy die castings, extra attention should be paid to avoid uneven wall thickness caused by excessive grinding.
