High-Productivity Grit by W Abrasives™

High-Productivity Grit designed for desanding operations 

HPG, our Premium cast steel media for foundries, is an angular abrasive specifically designed to improve the cleaning and descaling performance of shot blasting. It works faster, makes cleaner parts and lasts longer than typical cast steel shot used in foundries. Its ability to remove and clean sands, resins or steel scale is unmatched.

Cleaning efficiency

  • Optimal grit hardness allows the use of smaller particles for better and faster cleaning & desanding of internal and external casted surfaces
  • Provides a smoother and more uniform surface profile Thanks to its superior efficiency and resistance to breakage, HPG can be used with higher than standard projection velocities (90 m/s or above) in order to treat difficult parts or areas that cannot be properly cleaned with standard shot.

Total Cost Reduction by 15%

Due to its higher performance capability, typical savings are:

  • 10% increase in productivity / capacity
  • 10% reduction in blasting cycle time
  • 30% less energy consumption (ISO 14001)
  • 10% decrease in abrasive consumption
