We understand the critical role that precision and durability play in the food and dairy industries. Our team expertly rebuilds and repairs mutator and dasher shafts, barrels, tubes, and homogenizers, using cutting-edge techniques like precise re-chroming, spline cutting, and specialized overlays. These processes restore your equipment to like-new condition, ensuring optimal performance and longevity in high-demand environments.

• Dasher and Mutator Shafts

  Our team specializes in restoring mutator and dasher shafts to optimal performance. Services include:

  • Multi-Spline and Square Drives: Precision re-splining and drive restoration for smooth, efficient operation.
  • Re-chroming of Bearing and Seal Areas: High-quality chrome application ensures longevity and reduces wear.
  • End Replacement and Pin/Bushing Replacement: When necessary, we replace ends, pins, and bushings to prevent premature scoring and maintain functionality.
  • Bent Shaft Correction: Straightening bent or twisted shafts to prevent scoring on barrels and tubes, ensuring long-term reliability.

• Barrels and Tubes

  For damaged barrels and tubes, our proprietary “Save Our Tubes” process addresses pits, cavities, and other wear without compromising wall thickness. Our overlay application guarantees no chipping, flaking, or peeling, with a chrome finish of 8-10 RMS.

  • Material Types: Steel, Nickel, Stainless Steel
  • Barrel/Tube Types: Bash, Oval, Round
  • Turnaround: Re-chromed tubes and barrels delivered in as little as 7 to 10 days.

• Homogenizer Rebuilding

  Experienced in APV, Manton, Gaulin Tetra-Pak, and Niro Soavi homogenizers, we offer complete rebuilds that restore performance to OEM standards.

  • Wet-End Rebuild: Includes full disassembly, polishing, valve rebuilds, and pressure testing, with the option for witnessing tests.
  • Piston Rebuilding: We remove existing coatings, apply new chrome or spray coating, and grind pistons to OEM specs.
  • Drive-End Rebuild: Stripping, repainting, and complete drive-end restoration to ensure reliable operation.

  All rebuilt homogenizers come with a one-year warranty, and cylinder blocks are guaranteed to be fully operational upon arrival.

Metal Spraying offers solutions for high-wear parts that require exceptional durability in extreme environments. We use HVOF, electric arc, and ceramic coating systems for applications requiring resistance to erosion, corrosion, and wear. 

• Process

  In our thermal spray coating process, tiny particles of metal or other materials are melted and sprayed onto a surface to create a durable, protective layer. Using a thermal spray gun, the material is heated and then shot at high speed onto the surface, building a coating that enhances the base material’s performance and longevity. This process adds durability and can help extend the life of worn or damaged parts without causing them to overheat.

• Industries Served

  Virtually any industry can benefit from the advantages of thermal spraying. Common applications include mining, power generating, oil and gas refining, chemical, and pulp & paper industries.

• Coating Options

  Tungsten carbide, nickel alloys, cobalt alloys, and more, available in various grades and compositions for tailored protection.
