Problems solved by technology

[0004] In the existing technology, the nickel-based alloy material is usually combined with the inner cavity of the die body by plasma spray welding, that is, a nickel-based alloy layer is formed in the inner cavity, but the spray The welding process has the following shortcomings: first, due to the strict requirements and technical difficulties of the plasma spray welding process, it is difficult to guarantee the quality of spray welding, for example, cracking of the spray welding layer during use is common; second, the efficiency of spray welding is low , which is not conducive to meeting the requirements of industrialized enlarged production; third, the labor intensity of spray welding operators is high; fourth, because the die needs to be preheated before spray welding, it is often preheated with the mold in the furnace, thereby wasting energy; fifth, Due to the need to invest in special spray welding equipment and skilled personnel to operate, not only the increase in equipment investment will lead to a significant increase in mold costs, but also the consistency of quality is difficult to guarantee, because even if the same operator, often due to differences in experience, Differences in the sense of responsibility, emotions and / or mental states or changes will result in different spray welding quality; Sixth, due to the lack of compactness of the nickel-based alloy layer sprayed into the inner cavity, it will appear uneven, Weld spots, pores and cracks, etc., so that the service life of the die cannot reach the desired level
