Mass Finishing for Improved Surface Properties

During a mass finishing operation, surface properties of metallic components are improved through the interaction of media, and chemical compounds in the appropriate type of equipment.

Typically with the addition of water, how these elements interact determines the efficacy of the process. Through the movement created by the equipment, the media, mass finishing compound and metallic components all work on each other, with the goal of: removing burrs, radiusing edges, improving surface properties, cleaning, descaling, and/or deflashing.

Synergy between elements

Hubbard-Hall manufactures a full line of mass finishing compounds designed to work synergistically with the correct equipment and media:

  • Equipment Types – oblique barrel, vibratory bowl or tubs, centrifugal barrel.
  • Media Types – ceramic, plastic, metal, organic.

Mass Finishing Compounds

  • Cleaning Compounds
    Designed remove undesirable surface contamination from parts. The appropriate compound is matched with the metal being cleaned & media being used.
  • Descaling Compounds
    Used to remove scale, rust and oxides from metallic surfaces by using either acidic or alkaline compounds.
  • Deburring Compounds
    Designed to assist burr removal by keeping the parts and media clean. Also provides corrosion resistance to the parts and media when required.
  • Burnishing Compounds
    Generally used to improve reflectivity or brightness of the metal surface by providing lubricity to the media while cushioning the parts against damage. The compounds may also control part color, remove oxides and prevent corrosion.
  • Cutting Compounds
    Formulated to facilitate stock removal by chemically accelerated mass finishing chemistries or by the use of abrasive compounds. Also can be used to remove heavy scales and oxides from metallic surfaces.
