As we all know, the quality of aluminum profiles sold in the aluminum profile market is uneven, leading to many unqualified aluminum profile products on the market. Some unscrupulous merchants, in order to seek huge profits, did not hesitate to reduce costs, leading to chaotic sales in the aluminum profile market, and consumers did not know how to judge whether the aluminum profile was qualified. So how should we judge whether the aluminum profile processed by CNC is qualified?
Method to judge whether CNC machining aluminum profile is qualified:
1. Film thickness: In order to reduce electricity bills, save costs, and reduce the oxidation time, unqualified merchants will cause unqualified oxide film thickness and affect the corrosion resistance of industrial aluminum. The film thickness of aluminum profile CNC processing should not be less than 10μ.
2. Shortening the sealing time will result in poor sealing, which will affect the corrosion resistance and pollution resistance of the aluminum profile.
3. The extruder is too old, or the CNC processing equipment is outdated, which will cause the aluminum profile and the parts to not fit well, and even worse, it cannot be used.
4. The thinner the wall thickness of the profile, the lower the cost. The wall thickness of the qualified profile needs to be measured with a caliper and cannot exceed or fall below the tolerance range. This is the so-called unqualified wall thickness.

How to distinguish whether it is inferior aluminum profile
Aluminum is divided into raw aluminum and cooked aluminum. Raw aluminum is less than 98% aluminum, which is relatively brittle and hard, and can only be found in sand casting products; cooked aluminum is more than 98% aluminum, which is soft in nature and can be rolled or punched in a variety of utensils. So when ordering aluminum profiles, how do you tell whether it is inferior aluminum profile?
Process measures and operating skills to reduce deformation of aluminum processing
There are many reasons for the deformation of aluminum parts, which are related to the material, the shape of the parts, and the production conditions. There are mainly the following aspects: deformation caused by internal stress of the blank, deformation caused by cutting force and cutting heat, and deformation caused by clamping force.
