Industrial Heat Treatment
The VIF-1200 reaches up to 1600°C under vacuum, with a temperature uniformity of ±5°C across the melt zone. This ensures consistent alloy chemistry and minimal contamination during melting of high-performance ferrous alloys.
The SP-800 uses a multi-zone heating system with programmable cooling cycles. You can set ramp-down rates from 0.5°C/min to 10°C/min, allowing precise control over microstructure development in powder metallurgy components.
The QTL-500 consistently delivers surface Vickers hardness up to 60 HRC on ferrous alloys, depending on the specific grade and section thickness. Real-time monitoring of oil quench temperature and tempering soak time ensures repeatability across batches.
Yes. The vacuum environment prevents oxidation and decarburization, making it suitable for reactive ferrous alloys. The furnace includes a controlled argon backfill option for post-melt processing steps.
For a 200 kg batch of medium-carbon alloy steel, the complete cycle—including austenitizing, oil quench, and tempering—takes approximately 4 to 6 hours. Cycle time varies with part geometry and target hardness.
For standard ferrous powder compacts, the SP-800 includes a pre-heat zone that removes lubricants and binders before the high-temperature sintering stage. This eliminates the need for a separate debinding furnace in most production lines.

Melting under vacuum eliminates oxidation, giving you ferrous alloys with consistent chemical composition and fewer inclusions.
Multi-zone heating and programmable cooling produce dense, wear-resistant components with uniform mechanical properties.
Automated oil quenching and tempering cycles deliver surface hardness up to 60 HRC and improved fatigue resistance for kinetic parts.
Temperature and cooling rate data are tracked per batch, so every component meets the specified Vickers hardness and tensile strength.
Gears, shafts, turbine blades — our furnaces accommodate complex shapes up to 1200 kg without distortion or uneven hardening.
Vacuum induction and sintering processes that deliver repeatable Vickers hardness and tensile strength for high-stress kinetic components, backed by controlled quenching and tempering cycles.
Our vacuum induction furnaces operate below 10⁻² mbar, preventing oxidation and decarburisation during melting. This ensures the chemical composition of ferrous alloys stays within specification, directly affecting surface hardness consistency.
Each component follows a programmed cooling curve tailored to its section thickness and target hardness. Oil, polymer, and gas quench options allow us to achieve 55–62 HRC on high-stress kinetic parts without distortion.
Post-quench tempering cycles are calibrated to balance hardness with impact resistance. We monitor tempering temperature within ±3°C across the load, reducing residual stress while maintaining tensile strength above 1200 MPa.
Our sintering plants consolidate ferrous powders to >98% theoretical density, minimising porosity that can initiate fatigue cracks. Multi-zone heating and programmable cooling produce uniform microstructure across complex geometries.
Every heat treatment cycle is recorded with temperature, pressure, and quench rate data. Customers receive a traceable report for each batch, supporting quality audits and material certification requirements.
Gears, shafts, and turbine blades treated in our furnaces have accumulated over 50,000 hours in service without hardness degradation or premature failure. Repeat orders from the same manufacturers confirm process reliability.
