Capability Evolution

Three Decades of
Compounding Expertise

Each era added a capability layer that the next era built upon. Click any decade to expand the full technical record — processes, certifications, and customer approvals.

Integrated ML-based process control that reads thermocouple arrays, carbon sensors, and quench bath telemetry in real time. Adaptive profiles compensate for load density, ambient conditions, and alloy batch variation — holding ±2°C uniformity at scale.

Temper's LPC line gave us sub-0.001" case depth repeatability across 40,000-piece transmission gear batches. First vendor to pass our CQI-9 audit without a single corrective action.

We moved our 4340 output shaft hardening here after two distortion escapes at our previous vendor. Three years in, zero PPM to assembly. Their vacuum furnace data packages are the cleanest I've seen.

The AI monitoring platform caught a thermocouple drift mid-cycle that would have scrapped a $180K prototype load. They flagged it, compensated in real time, and sent us the corrected profile within the hour.
