Watermark is generally shallow in the casting surface; and cold shut lines that could spill into the interior of the casting. Hot crack: a uneven thickness when casting solidification process produces stress; b premature ejection Guangdong zinc alloy products, metal strength is not enough; the top of the uneven force when c d high mold temperature so coarse grains; e harmful the presence of impurities. These factors are likely to crack. When there Watermark casting, cold shut lines, hot cracking, when the plating solution will penetrate into cracks, converted to steam during baking, pressure from the top plating layer blistering.
