      1. In the process of forming the mold, after basically determining most of the processing steps, it is found that some polished holes have some sand holes or some inexplicable particles appear, which will cause the whole parts to be scrapped.

      2. Generally, in the aviation military, the requirements for the 7075 aluminum plate are very high. Therefore, in terms of quality, it is absolutely strict. Why some aluminum plates will be less in the process of review after processing. The deformation, and some even completely deformed after 2 days.

      3. The requirements for the 7075 aluminum plate are very high, and the strength of the aluminum piece is required to be stable, qualified, and does not undergo any deformation for a certain period of time.

      When we are experiencing the above problem, how should we solve it?

      First of all, some aviation aluminum alloy products are subject to ultrasonic testing, no sand holes, and horizontal stripes, small bubbles and magazines. Now that the heat treatment technology is becoming more and more mature, the strength and hardness of the product are guaranteed to be the same at a thickness of 30 cm. In fact, the perfect pre-stretching can eliminate the internal stress and is completely eliminated, so the deformation will not be encountered during the processing, as well as the bending. Finally, when the whole work is completed, it is necessary to check whether the indicators are normal.
