High Velocity Coating
High Velocity Coating (HVC) is a revolutionary product that greatly extends the life of wear-prone, circular-shaped metal parts, and it’s available exclusively from EPM.
HVC-coated surfaces have an even porosity and constant Rc70 hardness, which significantly retards surface wear caused by friction and rubbing. This doubles the life of components and extends seal life two to three times compared to other coating treatments.
Why It Works
Even when new, most metal coatings reveal micro-cracks under magnification. With time and use, these cracks allow rust and corrosion to invade the surface, adversely affecting the performance and wear life of the component. However, the homogeneous properties inherent in HVC dramatically retard corrosion, so surfaces (and any seals which come in contact with them) last more than twice as long.
HVC is ideal for components such as:
- Chromed cylinder rods
- Stainless steel pins
- Laminating rollers
- Deburring machine rollers
- Strut rods
- Rotating shafts
- Linkage pins
...and any other application where uniform hardness, corrosion resistance and extended performance are desirable.
The HVC Process
Before HVC coating is applied, each piece is carefully inspected to insure structural integrity. Old coatings and surface imperfections are ground away, using computer-controlled precision lathes. Special abrasive belts were developed in partnership with 3-M Corporation for this process.
We use an electronic surface analyzer to determine the best grit texture to prepare the surface and the component is then grit-blasted to achieve the optimum surface for coating.
Cutting-edge technology with application-specific formulas
During the coating process, the component rotates inside the HVC cabinet while the Hybrid Jet System™ applies powdered coating material through high-temperature gasses at supersonic speed.
HVC’s chemical formulas can be customized to each component’s application and the number of coats applied varies with each piece. The result is a dramatic improvement in component performance and wear life.
Final finishing is done on special computer-controlled, diamond-belted lathes.
