How do we deal with the surface defects of sheet metal cabinet Zhongshan Mingruo Metal Products Co.,

[Sheet metal chassis] The common shortcomings of the cabinet's exterior surface include sundries at the bottom, severe color difference, surface scratches, coating dropping, paint flow, exposed base material, powder accumulation and so on. These are some common shortcomings in the current cabinet's sheet metal processing.

The causes of the first appearance scratches are complex and run through the whole process of commodity production, but they can be roughly divided into two categories:

First, scratches occur when goods are processed.

The second is the scratches of logistics in the production process.

The second coating dropping is mainly due to the poor adhesion between the coating and the substrate. The primary methods to detect the adhesion are impact test and scratch test.

The third exposed base material is that there is no coating on the surface. The primary cause is leakage and large area scratch.

Fourth, severe color difference refers to the same appearance of color inconsistency, color difference value beyond 1.

The fifth floor impurities refer to the shortcomings that occur when the surface of the base material is not disposed of cleanly when it is disposed of. It is the primary reason for the coating dropping.

Sixth, the principle of the occurrence of paint flow and powder deposition is generally appropriate. Only paint flow occurs when spraying paint and powder deposition occurs when spraying plastic, all of which are due to the shortcomings of too large and too thick spraying amount.
