Interesting Features

  • Non-electric design for simplicity
  • High fill rate (75%) compared to electrolytic barrels (~35%)
  • Elevated temperature tolerance for demanding processes
  • Efficient drying in-barrel for faster turnaround

Key Benefits

  • Processes Many Parts at Once: Ideal for bulk phosphating of small components
  • Ensures Even Coating: Tumbling motion promotes uniform layer and prevents nesting
  • Reduces Handling Damage: Gentle rotation minimizes scratches and bends
  • Improves Surface Prep: Dislodges oils, scale, and rust during immersion
  • Increases Line Efficiency: Streamlined operation reduces labor, energy, and chemical use

What to Consider When Getting Started

  • Application Type
  • Part Size & Shape: Determines barrel dimensions and perforation size
  • Batch Load Weight: Impacts gear durability and drum strength
  • Barrel Size: Must match tank and hoist system
  • Material of Construction: Stainless steel or polypropylene for chemical compatibility
  • Perforation Size: Smaller than the smallest part (typically 1/16″–1/8″)
  • Temperature Resistance: Rated for 160–210°F
