How To Judging The Qualified Aluminum Profiles Processed by CNC

As we all know, the quality of aluminum profiles sold in the aluminum profile market is uneven, resulting in a lot of unqualified aluminum products on the market. Some bad businesses, in order to seek profits at the expense of reducing costs, 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 profile processed by CNC is qualified? The following Shanghai Jin aluminum to give you a brief introduction.

How to judging whether CNC machining aluminum profiles is qualified:

1, Film thickness: bad businesses in order to reduce electricity costs, save costs, reduce the oxidation time, resulting in unqualified oxide film thickness, affecting the corrosion resistance of industrial aluminum, aluminum CNC processing out of the film thickness should not be less than 10 μ.

2, shortening the sealing time will cause poor sealing, which will affect the corrosion resistance and pollution resistance of aluminum profiles.

3, the extrusion machine is too old, or CNC processing equipment is relatively outdated, which will lead to aluminum profiles and parts are not strong, or even can not be used.

4, the thinner the wall thickness of the profile, the lower the cost, the qualified profile wall thickness needs to be measured with calipers, can not exceed or below the tolerance range, which is the so-called wall thickness is not qualified.
