[0002] When processing a metal frame with filaments, the metal frame body is generally made by stamping, and then the pre-made filaments are welded to the metal frame body. This involves three separate production processes: stamping the metal frame body, making filaments, and welding filaments. Different processing equipment is used, and the semi-finished product needs to be transferred to another equipment for processing. The processing efficiency is low, resulting in high production costs. If all the processing steps can be completed in one mold, the finished product can be directly produced, and continuous processing and batch production can be carried out, the processing efficiency will be greatly improved and the production cost of the enterprise will be reduced.
