stamping manufacturers.Why complete inspection of zinc alloy die casting material before surface treatment

　　Zinc alloy die casting before electroplating, electrophoresis, painting, sandblasting and other surface technology to strictly check the blank, is an important step to ensure the quality of zinc alloy die casting after electroplating, zinc alloy die casting after the appearance of burr, gate, cross line, tumor and other problems, strict inspection to remove difficult to grind or smooth surface technology brought quality problems of the blank. Effectively reduce the repair rate after surface technology, saving costs.

　　The mechanical grinding tool is a soft elastic wheel, the zinc alloy is soft, and the grinding wheel made of white cotton is needed for grinding. When the grinding wheel is used in the die casting, the grinding particles can be stuffed into the grinding wheel, weakening the cutting performance of the grinding particles, so the formed die casting will not change the geometric shape, and the appearance is more lubricated after grinding.

　　The working surface of the grinding wheel is coated with red grinding paste, which can hide countless grinding particles, make the appearance more flat and lubricated, and the working force of the die casting needs to be small and average. The surface process quality of the new zinc alloy die casting directly affects the quality of the finished product, so it must be patiently maintained during polishing.
