When the die-casting mold is in use, the die-casting mold will turn yellow. So what is the reason for this? Let’s take a look specifically below.
①Insufficient coating of zinc alloy die castings leads to yellowing;
②The high porosity of the coating leads to yellowing;
③There are impurities in the plating solution, which are contaminated to cause yellowing of the die casting;
④Insufficient electroplating time will also cause yellowing of zinc alloy die castings;
⑤Insufficient washing after electroplating leads to yellowing;
⑥ Stored in a messy, messy and dirty space after electroplating will also cause the zinc alloy die castings to turn yellow.
