Transform Your Engines with Plasma Transferred Wire Arc

Thermal Spray Coating for Aluminum Engine Production.

Coating and Additive Manufacturing – PTWA

Advanced Tribological Characteristics

Coated aluminum cylinder bores offer the same tribological characteristics of steel.


Lower Vehicle Weight

PTWA allows automakers to reduce cylinder block weight and eliminate design restrictions.


Long-term Benefits

PTWA allows automakers to improve durability and ultimately help lower overall costs.  


The Bottom Line

Increased productivity combined with stronger, lighter and higher performing engine blocks.

  • ½–2 times more durable
  • Up to 10 pounds lighter than cast iron liners
  • Increased fuel economy
  • Reduced friction (up to 25% less while idling)
  • Lower emissions (improved FM EP up to 25% friction measure)
