Forging

 

What is Forging?

It is a method of plastic deformation that is achieved by stroking and/or pressing metal material.
The stroking and/or pressing produces a dense and uniform metal grain flow to give superior mechanical properties such as high tensile strength and hardness.
The processing methods have been developed from the hand-made tools used by ancient blacksmiths into a variety of modern techniques such as our closed die screw press system.

Advantage of Closed Die Screw Press Forging

The energy from high-speed spinning wheels is transferred to the screw and its rotary motion is converted into a vertical motion.
The stroke energy of the vertical motion is stronger than a hammer or crank type press so that 1 or 2 blow formation is possible.
In addition, the die forming creates products with less dimensional tolerance.  This results in precise and complicated shapes such as hollow or extruded shapes with a draft angle of 0 to 1 degree attainable.  This near NET shape reduces material waste and job labor by skipping or reducing the machining process.
In this way, our closed die screw press method balances productivity with dimensional preciseness.
