Triple blade structurePipe Crimping Tool
Allows for the crimping of two pipes into a single long pipe.Manual Earth Auger Drill
Makes well rounded beautiful holesSwaging Process (Rotating Cold Forging Process)
The swaging process (rotating cold forging process) is a process in which a divided die rotates and is hammered to squeeze the outer diameter of a round bar or pipe material.
The Benefits of Cold Forging
- Cost reduction can be achieved by eliminating material waste and loss.
- The strength of parts can be improved by work hardening.
- Environmentally friendly

Three Features
A Beautiful Surface Finish
Material costs are reduced because material powder is not produced during the cold forging process. It creates an extremely beautiful processed surface when compared to conventional cutting processes. Metal tubes and solid materials etc. are formed by hammer processing. A wide range of dimensions are possible including steel pipe columns.

An Increase in Strength
Surface roughness can be strengthened by high-speed striking technology through rotary forging. The strength of parts are increased by work hardening. It is also a used wodely in automotive part manufacturing.

Compatible with a wide variety of materials
It is possible to use cold forging when working with hard to process materials such as titanium and stainless steel. Applicable materials include: Pure titanium, titanium alloys such as beta titanium, NT alloy, as well as rubber metals, stainless steel, aluminum, nickel silver and more.
