Mining and tunneling cutting tools built for the harshest conditions. PLASMA picks, cutters, and drill rods last significantly longer than standard consumables — cutting downtime and cost per tonne.
Every product can be configured by carbide grade, geometry, and hardening profile. Talk to our team for a custom solution.
The difference starts at the microstructure. The alloy ring turns the brittle interface into a gradual metallurgical transition — solving unsynchronized wear between the steel body and the carbide. Visible gains, shown in the field photos throughout this site.
CNC-machined alloy steel body.
Tungsten carbide tip brazed into the machined steel body.
The alloy ring is fused into the body — a deep metallurgical bond with gradient transition.
In-house hardness testing and dimensional checks.
Every variable that affects service life — from alloy chemistry to heat-treatment curves — is controlled and recorded under one roof in our Chengdu plant.

Machining, brazing, high-energy-beam ring embedding, heat treatment and inspection — all in-house.

Rod turning, machining and heat-treatment lines producing drill rods and drill steel.
Mining, tunneling, trench cutting and foundation works — one hardening technology across all of them.
