In the zinc alloy die casting production process, due to the influence of various factors, the burr phenomenon of zinc alloy die castings is inevitable. Burr affects the surface appearance of the product and adversely affects production. So, in the face of burrs, as a manufacturer, how to solve it? The common deburring method of zinc alloy die-casting enterprises is manual deburring, using sandpaper, grinding head and other tools to remove the burrs on the surface of zinc alloy die-casting parts. However, this method has low efficiency and is only suitable for products with simple structures. Secondly, mold deburring and grinding deburring are also commonly used. It is suitable for zinc alloy die castings with simple parting surfaces, and the effect is better than manual. Grinding and deburring is to remove burrs by sandblasting, roller and vibration, but the effect is not ideal, and subsequent manual or other methods may be required. The production process is more complicated. In addition to the above three common deburring methods for zinc alloy die castings, there are freezing method, thermal explosion method, engraving machine method, chemical method, electrolysis method, high pressure water jet method and ultrasonic deburring method. It is very important to correctly deal with burrs in zinc alloy castings.
