Carbide and stainless steel composite band watch band using stainless steel sheet

摘要

It is a technology for manufacturing a hard metal band for wrist watches (HARD METAL BRACELET FOR WRIST WATCH). It uses a combination of high precision welding technology and machining technology to minimize the defect rate and high productivity, (1) and stainless steel sheet (2) are perfectly bonded to each other by brazing, and then the stainless steel (3), which is a functional part, is completely bonded (STOP WELDING) method to prevent deformation due to high heating of stainless steel which is a functional part, so that defects do not occur even when used for a long time. Particularly, the steel material covering the upper surface protects the functional stainless steel The durability of the part is further improved, and it is possible to utilize the characteristics of the super-hard material of excellent gloss without particularly scratches This is a technique for manufacturing a carbide band for a wrist watch that can be used semi-permanently.
