PRECISION FORGING

2,500-Ton Hydraulic Press

Our undercarriage components begin their life under immense pressure. This process refines the steel grain, eliminating weaknesses and ensuring unparalleled strength for mining applications.

Advanced induction hardening lines guarantee a consistent 58-62 HRC surface hardness depth. This critical treatment extends component lifespan, drastically reducing fleet downtime.

HEAT TREATMENT

Heat treatment- Carburization

Carburizing heat treatment is a core process for machinery undercarriage parts. Workpieces go through carburizing, quenching and tempering in high-temperature furnaces to achieve a hard wear-resistant surface and tough core.
