Pak piston is manufactured from high quality aluminum ingot based in technical of vehicle engineering, durable under high temperature & high pressure in combustion, explosive at head of piston and speed when friction between piston & liner. With our special techniques we can control shape expansion of all three parts of piston (head of piston, piston pin, piston skirt). Each of Pak pistons can provide you the accurate size and weight, which will give you long-lasting engine performance.
Piston must be enduring with all working conditions and lightweight to minimize inertia on bearing. In addition, piston ‘s structure should be parabola shape and have metal sheet that holds structure of inside piston to reduce shape expansion of piston when combustion strokes.
- Cu = 0.8~1.30 %
- Mg = 0.7~1.3 %
- Ni = 1.0~2.5 %
- SI = 11.0~13.0 %
- Fe = < 0.5
- Zn = < 0.1
Properties
- Capability working under high temperature combustion.
- Endurable piston ‘s structure can prevent from losing shape when working under intense pressure.
- All pistons have equality of weight to give more powerful engine performance.
- Special invention of metal sheet to hold inner structure.
- Strongest ring groove can be tolerated stress and friction.
