Problems solved by technology

First of all, the initial investment required by the traditional process method is large, and the equipment investment required is relatively large, and the equipment occupies a large area.
Secondly, the production cost of the traditional process method is high, the process is cumbersome, the production speed is slow, the material loss, tool consumption, production energy consumption and labor intensity are high
Furthermore, the surface treatment involved in the production of traditional craft methods is polluting to the environment
The biggest shortcoming of the traditional process method is that it can produce welding wire made of pure aluminum material more stably, but the performance of the aluminum alloy welding wire produced cannot meet the requirements of practical applications, mainly because the composition and structure of the alloy welding wire cannot be effectively controlled, which affects the mechanical properties of the welding wire. The performance and welding performance are poor. At the same time, the surface finish, cleanliness, uniformity of wire diameter, wire pitch and helicity cannot be guaranteed. The product has serious quality instability problems and low yield. It is difficult to meet the requirements of automatic continuous welding. requirements
