Processing Technology
Each piston is manufactured through a complete process chain: alloy steel forging → normalizing → rough turning → quenching and tempering → precision CNC turning → honing → surface treatment → quality inspection. The differential hardening creates a wear-resistant surface layer while maintaining core toughness for impact absorption.
OEM Quality Assurance
Manufactured to original equipment specifications with strict dimensional tolerance control. Each piston undergoes hardness testing and dimensional inspection before shipment. Compatible with KOMAC KB400, KB1000, and KB1500 hydraulic breaker models used in mining, quarry, and heavy construction applications.
