【 WPC Treatment (Precision Shot-peening) 
Nissin Kiko's various mechanical equipment and processing technique.


Nissin Kiko make suggestions the cost reduction by WPC Treatment.

What is WPC Treatment ? (Wonder Process Craft)
Lifetime of Metal parts, Die, Cutting tools and Industrial tools increase several times by doing special precision shot-peening at surface of metal manufacture. The treatment process is innovative.
Fuji Manufacturing Co., Ltd. Joint patent No.1594395

Advantage of WPC Treatment、Shot-peening and Blast

WPC処理後   Extension of fatigue life
Improvement of abrasion quality
Prevention of stress corrosion,        intergranular corrosion and electrical        corrosion
Prevention of low-temperature        brittleness
Reduction of sliding resistance and fluid        resistance
Reduction of noise
Diffusion of separating layer by surface        diffusion process
Modification of leak from molded article        mesh and pinhole
Prevention of surface diffusion process        asymmetry
Metal covering treatment
Improvement of adherence strength for        various paint and coat
Electrical resistance down and        magnetic field stability
Noise control
Stiffen sliding resistance
Finery,deburring and descaling
