Heat treatment is where a forging earns its properties, and JPF keeps the entire spectrum in-house —all core heat treatment processes ,every cycle recipe-driven and digitally logged.
Our SCADA-monitored, CQI-9 compliant facilities run seven core processes — normalising, isothermal annealing, controlled cooling, hardening and tempering, atmosphere-controlled gas carburising, press quenching, and induction hardening and tempering — giving complete command over case depth, core hardness and distortion for every component we make.
The line is anchored by sealed-quench furnaces with 1,500 kg charge capacity for carburising under precisely controlled atmospheres, and induction hardening systems from 50 kW to 600 kW covering everything from selective hardening of small levers to deep-case treatment of heavy shafts and gears.
Every cycle is recipe-driven and digitally logged, so each batch carries a verifiable thermal history — and every part leaves with the metallurgy its application demands.
