Improving the functional and aesthetic values

A variety of needs for surface conditioning by deburring, descaling, roughening, etc. through surface reformation for durability and reliability improvement are supported.

  • Blasting
  • Sand removal from castings
  • Deburring
  • Descaling
  • Removal of impurities
  • Surface roughening
  • Patterning
  • Edge finishing
  • Rounding
  • Flat finishing
  • Glazed finishing
  • Mirror finishing
  • Shot peening

Shot Peening

Shot-peening improves the fatigue strength and stress corrosion crack resistance of parts. It greatly contributes to environmental protection, energy saving and reduction of CO2 emissions in the next generation.

DASP process TM

DASP process TM
By the residual compressive stress of over 1800MPa and the surface hardness of more than 100Hv, Materializing the world's highest level of fatigue strength


This process reduces casting faults by modifying the die casting mold surfaces. It contributes to cost savings and reduction of CO2 emissions.
