The discoloration of precision stamping parts has a certain
relationship with the structural shape, the performance of the plating
solution, and the running speed. In view of these factors, how can
precision hardware solve the problem of discoloration of the coating?
For
the structural shape, this is a physical phenomenon, and it is
impossible for us to change the structural shape of the workpiece for
electroplating. Due to the characteristics of the current, we cannot
change the current distribution in different parts of the workpiece
during the electroplating process. We can ignore this reason. Regarding
the speed of the workpiece, this is a better solution. As long as we
adjust the speed regulator of the extraction machine on the
electroplating line to the appropriate speed. In this way, the thickness
of the coating reaches the standard and is evenly distributed, and the
coating is not easy to change color.
The performance of the
plating solution is a key issue, and it is an important starting point
for us to solve the discoloration of the workpiece. Therefore, when we
choose the plating solution, we must test and compare repeatedly.
Because the performance of the plating solution is transformed through a
kind of open-type transformation, that is, the crystallization of metal
ions on the precision metal stamping parts.
The crystal is fine
and the gap between the crystal nucleus and the crystal nucleus is
small, so the protective ability of the coating is strong, that is, the
anti-corrosion and anti-oxidation ability is strong, and the coating is
not easy to change color. On the contrary, if the crystal is rough, the
gap between the crystal nucleus and the crystal nucleus is large, and
its protective ability is poor, and the coating is easy to change color.
In this way, when we choose a plating solution, we must choose a
plating solution with fine crystals to electroplate the workpiece.
