With the widespread use of aluminum profiles,
motor housing aluminum extrusions processing manufacturers are also increasing, but because of the uneven processing technology of various manufacturers, the quality of processed products also have concave and convex. So, in the choice of motor housing aluminum extrusions products, how should we judge its quality?
Methods to identify the quality of motor housing aluminum extrusions:
1. Carefully inspect the surface of motor housing aluminum extrusions for cracks, spalling, corrosion and bubbles. If these phenomena occur, it indicates disqualification. Good motor housing aluminum extrusions have a smooth surface.
2. Motor housing aluminum extrusions oxide film formed in anodic oxidation, has the role of protection and decoration, can be detected by eddy current thickness meter.
3. Text for motor housing aluminum extrusions design surfaces is usually printed in inkjet code and has clear text and common symbols such as trademark logos, manufacturers, addresses and telephone numbers. The real text on the surface of the fake aluminum is mostly printed by ordinary printers, the text is blurred, and the display of the manufacturer and the monitor is average.
4. Corrosion resistance, which mainly affects the life of aluminum profiles, corrosion resistance check includes copper accelerated acetate spray test and alkali drop test. The alkali drop test is introduced here. The test is easy to be roughly judged outside in summer. In order to ensure the accuracy of the test, it must be carried out under strict conditions in the laboratory.
