Exhaust valves for racing engines

Under the extreme pressures experienced in racing engines, exhaust valve stems were breaking with unacceptable frequency
 

Vibrogrooving creates an oil reservoir on the metal surface, while FriCSo’s polymer lapping adds an oil-retaining organic nano-layer, hardens the metal surface, and produces an extremely smooth surface with reduced coefficient of friction. FriCSo polymer lapping can be performed in-line on the current superfinishing machines. No capital expense and no change in production throughput are required. 

• Reduced breakage and improved wear and stem lifetime
• Repeated reorders from customer
