Tungsten Steel Tip Patch Hooks-·Vacuum Brazing Process.

                               ·The cutter body is sintered by ultrafine granular tungsten carbide powder,

                                 Therefore,the cutter is denser and the unit is more resistant to wear.

                               ·After cutting Edge Passivation Treatment,slow the early wear off of the hook edge.

                               ·We are the first company to adopt half nested brazing process in china, 

                                 with tungsten steel not in direct contact with the needle,so it can reduce the damage to the needle.
