Excellent casting quality

Excellent casting surface quality allows reduction of machining additions and thus reduces/eliminates the machining.

The high rate of cooling during the metal solidification in a permanent metal mould delivers increased alloy thickness and fine-grained structure of the casting, and excellent mechanical properties as a result.

High dimensional and shape stability and precision of castings are guaranteed.

The material consumption is significantly lower compared to conventional casting methods.

Permanent mold casting is suitable for both small and large series production.

 Anti-rotation pin special fixing

Special fixing of the ring’s anti-rotation pin by means of a special machine able to check drilling force and pin’s fixing on pistons one by one. 

Pinholes lubrication pockets

Obtained by CNC machining for best lubrication properties for racing pistons - evolution of the old lubrication holes. 

Improved Casting

The material consumption is significantly lower compared to conventional casting methods

Customized profiling
