Exploring Leading Processes, Core Selling Points, and Performance Advantages of Pistons

This film analyzes the technical value of the Piston from three dimensions: *Process 1.Liquid forging eliminates shrinkage and gas porosity, increasing material density by over 20%. 2.Fully automated CNC machining centers achieve micron‑level tolerances (≤±0.005mm) for skirt profile, ring grooves, and pin bore. 3.Graphite or MoS₂ solid lubricant coating on the skirt reduces start‑stop wear. Optional austenitic cast iron wear insert in the ring groove greatly extends the service life of the Piston Ring interface. *Selling Points 1.High‑silicon aluminum alloy (4032/2618) offers low thermal expansion, minimizing cold‑start noise. 2.Lightweight design reduces mass by 10–15% compared to conventional pistons, lowering reciprocating inertia and improving engine responsiveness. 3.Precisely matched clearance with the Cylinder liner reduces blow‑by and oil consumption. Supplied as a complete Piston Set, including piston, rings, pin, and retainers – a one‑stop solution for replacement.
