As we all know, the quality of aluminum profiles sold in the aluminum profile market is mixed, resulting in the emergence of many unqualified aluminum profile products on the market. Some bad merchants do not hesitate to reduce costs in order to seek huge profits, resulting in sales chaos in the aluminum profile Market. Consumers do not know how to judge whether the aluminum profile is qualified. So how should we judge whether the aluminum profiles processed by CNC are qualified? The following Shanghai Jin aluminum to give you a simple intro.
The method of judging whether CNC Machining aluminum profile is qualified:
1. Film thickness: in order to reduce electricity charges, save costs and reduce oxidation time, bad merchants lead to unqualified oxide film thickness and affect the corrosion resistance of industrial aluminum. The film thickness produced by CNC aluminum profiles should not be less than 10μ.
2. Shortening the sealing time will cause poor sealing, which will affect the corrosion resistance and pollution resistance of aluminum profiles.
3. The extruder is too old, or the CNC processing equipment is relatively outdated, which will lead to the poor coordination between aluminum profiles and parts, and even can not be used.
4. The thinner the wall thickness of the profile, the lower the cost. The thickness of the qualified profile needs to be measured by Caliper, which cannot exceed or fall below the tolerance range. This is the so-called unqualified wall thickness.
