The quality of consumables used in mass finishing is a key factor in surface processing.  Using consumables with a consistent high quality is crucial to attain set surface specifications, process times, costs and to manage considerations to any environmental impact.

There are in excess of 1700 types of vibratory media consisting of various shapes, sizes and incorporating a percentage of abrasive.  These are divided typically between ceramic and plastic families.

Ceramic Media Production

A ceramic media has a higher density than that of plastic media.  Ceramic chips of various shapes and sizes are formed, fired and held at certain temperatures and durations; providing an infinite range of variation and capability.

A consistent, supreme quality media is extremely important for the user to obtain a uniquely stable and reproducible surface finishing result.

Ceramic media is manufactured to exacting standards, controlled  in a fully-automated way.

Plastic Media Production

The manufacture of the plastic media is also totally automated.

The plastic media is of a lower density than that of the ceramic media, therefore it is suitable for a more gentle treatment of  critical component parts and softer metals.

The process involves mixing, forming and curing of the media and the whole process is computer controlled and continuously monitored.  This quality standard ensures a consistent wear and cutting performance, and repetitive results during the finishing process.

Surface Finishing Compounds

Compounds can be added to the vibratory process, optimising the surface specification for: degreasing, brightening, polishing, corrosion protection and producing surfaces free of stains.

Another important function is keeping the process clean.  The compound continuously flushes tiny metal particulates from the chip media and other contaminants out of the mass finishing system, keeping the media active and the parts free from contamination.

Depending on the specific process, compounds will provide various options of acidity and alkalinity as a pH factor.

Despite compounds being used for many years in mass finishing applications research and development constantly progress new formulations for special applications.

The range of different compounds is broadly diversified:

  • Liquid compounds
  • Recycling compounds
  • Powder compounds
  • Grinding compounds
  • Polishing compounds
  • Dry-polishing compounds
  • Cleaning (degreasing) compounds
