Reasons for surface depression in plastic electroplating

Plastic workpieces are prone to surface dents in environments of sunlight, rain, and high temperatures, which can result in unsatisfactory mirror effects and affect their aesthetics. So, what are the reasons for the surface depression of plastic electroplating?

In the previous sharing, Hebei Ruisite has already explained a lot about the application of plastic electroplating copper nickel chromium in automotive technology. The metallic texture of its mirror surface is also highly favored by everyone. However, in practical applications, the most intuitive way to judge the quality of the chrome plating layer is to look at the mirror effect.
Plastic workpieces are prone to surface dents in environments of sunlight, rain, and high temperatures, which can result in unsatisfactory mirror effects and affect their aesthetics. So, what are the reasons for the surface depression of plastic electroplating? Next, Hebei Ruisite will give you a lecture:

① The material used for plastic workpieces has poor temperature resistance and will soften at high temperatures, causing surface indentations;

② Plastic workpieces have stress, and when the temperature changes, the stress is released, causing surface indentations;

③ Defects in the design, such as the main surface thickness of the workpiece being too thin and the width of the skeleton being too large, can easily lead to dents;

④ There are problems with the injection molding process, incorrect process parameters, and insufficient injection molding;
