Heat Treatment
We can make a proposal for best condition to much all of use.
◆Bright Heat treatment Furnance
・We set process time for hardness and toughness

◆Vacum heat-Treatment Furnance
・We set process time for hardness and toughness

◆Subzero disposal
・We process for high hardness and stabilize the organization.

◆Nithiding
・depth of hardening is min 1mm.

◆Induction hardening
・We put products into induotion hardening and heat the surface.

◆Carburizing
・Hardening in the carburing materials.
 
Surface Treatment
We can propose the process methods wich can adaptable for using environments.
◆Passivation
・For the purpose of rust resistance.

◆Barell finish
・Surface roghness finish treatment.
・Rust resist treatment.

◆Electroless nickel plating

◆Aluminaless and Silliconless
・We take away the alumina and sillicon which are harmful when we use spinde motor and HDD.

◆Range designation surface roughness treatment
・We can manage the surface roughness
 
Minutureness production
