The process of working metal to desired shapes include forging, casting, press working and powder metallurgy.They are the processes of forming anything that supports this civilized society.
Among them, the forging is a process in which metal materials are hammered or pressed into required shapes.
It is able to manufacture products with higher strength (higher toughness) characterized by higher viscosity that causes less impact fracture compared with the two other processes.
While forgings do not greatly attract public attention in daily life, Japanese forgers are at a world-class level in forging technologies and productivity.
It is not too much to say that our very supply of high-quality and low-cost forgings enables forging users to produce world-famous automobiles and construction machines.
We at METALART are proud of being engaged in such “forging” to support the Japanese society.
【Characteristics of Forgings】
What symbolizes forging toughness is grain flow in product sections.
As trees put on annual growth rings, forgings retain the grain flow following their contours.This provides high strength, durability and impact values. Forgings, therefore, are used for critical parts of which safety is required.
