As we all know, the quality of aluminum profiles sold in the aluminum profile market is mixed, resulting in the appearance of many unqualified aluminum profile products on the market. Some unscrupulous businessmen, in order to seek profiteering at any cost, resulting in the aluminum profile market sales chaos, consumers do not know how to judge whether the aluminum profile is qualified. So how to judge whether the CNC machined aluminum profile is qualified? The following is a brief introduction to you.
Judge CNC machining aluminum profile is qualified method:
1, film thickness: unscrupulous businessmen in order to reduce electricity costs, cost savings, reduce the oxidation time, which leads to unqualified oxidation film thickness, affecting the corrosion resistance of industrial aluminum, aluminum profiles CNC machining out of the film thickness should be not less than 10μ.
2, shorten the sealing time will cause poor sealing, this point will affect the corrosion resistance of aluminum profiles and resistance to pollution.
3, the extruder is too old, or CNC machining equipment is more outdated, which will lead to aluminum profiles and parts with poor fit, or worse, can not be used.
4, the thinner the profile wall thickness, the lower the cost, qualified profile wall thickness needs to be measured with calipers, can not exceed or lower than the tolerance range, which is also known as the wall thickness is not qualified.
