Problems solved by technology

[0002] In the current square tube used in the manufacture of optoelectronic device casings, due to frequent changes in the working temperature of the casing and a large temperature gradient, the thermal stability and safety of the casing cannot be effectively guaranteed, resulting in the casing not being able to fully adapt to changes in the working environment
At the same time, the existing square tubes are all produced by the stamping process. This method has gradually failed to adapt to the performance and production requirements of modern industrial square tubes, especially for the manufacture of some special alloy square tubes. The traditional stamping process has a high scrap rate and precious metal materials The waste is serious, the work efficiency is low, and the quality consistency of the obtained products is poor. These shortcomings have led to the generally low level of domestically produced photoelectric square tubes. Such national monopoly has led to the fact that the demand for products of these grades is often restricted by others.
