. One of the biggest headaches we have in the mold manufacturing process is that after most of the processing is completed After the process, it was suddenly discovered that there were sand holes or unknown particles on the final polished surface, and the spring steel workpiece was now scrapped.
Answer The unique grain refinement process ensures that all aerospace product series have passed the ultrasonic flaw detection process inspection of aerospace aluminum alloy products, and are free of sand holes, horizontal lines, bubbles and impurities. With excellent heat treatment technology, the product can maintain consistent strength and spring steel hardness below the thickness. All production processes are computer controlled, with minimal human deviation, and the performance can be guaranteed to be the same in different batches of production.
.Our products are electronic manipulators and electronic tooling boards. This aluminum part is required not to be deformed even a little after being processed. Why is the spring steel that the European boards or domestic boards we bought in the market before one day or two after processing? Suddenly transformed in two days?
Answer The perfect pre-stretching process to eliminate internal stress completely eliminates internal stress. The product will not warp, crack or deform the spring steel during processing and stress.
.Our products are used for mechanical structural parts. Are the aluminum parts required to have stable and consistent strength and not break or deform at a certain point?

.When we process precision workpieces, we require very precise thickness and tolerances. If the tolerances are uneven, self-correction will not only increase costs, waste time, but sometimes also cause the workpieces to be scrapped?
Answer: All products comply with American Society for Testing and Materials specifications and aerospace material specifications. The tolerance index of most products can exceed the standard tolerance accuracy, and the tolerance index of some products can even exceed the standard tolerance accuracy.
After quenching and natural aging, aluminum alloys (such as aluminum and copper) are reheated to ~℃, and then quickly cooled to room temperature. The strength of the alloy decreases, becomes soft again, and the properties return to the newly quenched state. If placed at room temperature, Like the newly quenched alloy, it can still undergo normal natural aging. This phenomenon is called regression. The explanation for the regression phenomenon is that when the alloy is naturally aged at room temperature, the size of the formation zone is smaller. When heated to a higher temperature, these small zones are no longer stable and re-dissolved into the solid solution. At this time, the alloy is quickly cooled to room temperature, then The alloy returns to its newly quenched state and can still be naturally aged again.
In theory, regression treatment is not limited by the number of treatments, but in fact, it is difficult to completely redissolve the precipitated phase during regression treatment, resulting in local precipitation during the subsequent aging process, and the aging strengthening effect is gradually weakened. At the same time, during repeated heating, the solid solution grains tend to become larger and larger, which is detrimental to performance. Therefore, regression processing is only used for rivet alloys used to repair aircraft. This phenomenon can be used to perform riveting at any time, but it has no use value for other aluminum alloys
