2026-03-18 11:03:06
Industry: Open‑pit mining (copper ore & granite)
Equipment: Komatsu PC400‑8 / PC450‑8 excavators
Challenge:
A mining company in Indonesia was operating under 24/7 production with severe abrasion and impact. Standard bucket teeth wore out or fractured within 8–12 days, causing frequent downtime, high replacement costs, and inconsistent digging efficiency.
Solution:
We provided forged Komatsu‑compatible bucket teeth with optimized alloy composition and precision heat treatment. These teeth match OEM dimensions for perfect fit, higher toughness, and self‑sharpening tip design.
Results:
- Service life extended to 28–35 days (over 2× longer than standard teeth)
- Penetration improved by 15–20%, lowering fuel consumption per ton
- Breakage and chipping almost eliminated in high‑impact conditions
- Annual cost savings per machine: ≈ USD 11,000
Client Testimonial:“These Komatsu‑matched teeth are perfectly sized, extremely durable, and greatly reduce our maintenance workload. They are ideal for continuous mining.”
