Piston Pin
Factory
Plant Overview
Our factory produces solid piston pins for heavy‑duty truck, construction machinery and generator engines. Full‑in‑house production covers raw material inspection, precision turning, carburizing quenching, tempering and super‑finishing. Internal lab conducts dimension, hardness and metallographic tests. We support both mass production and OEM customization.
Core Differentiators
01 Premium Alloy‑Steel Raw Material
Heavy-load grade alloy steel with strict incoming inspection on chemical composition and microstructure.
02 Precision Turning & Super‑Finishing
Precision turning for stable tolerance. Multi‑stage super‑finishing delivers ultra‑smooth surface, lower friction with piston and bushing.
03 Controlled Carburizing Heat‑Treatment
Controlled carburizing achieves wear‑resistant hard surface and tough inner core. Resists cyclic impact, preventing fracture under heavy-duty conditions.
