Performance Highlights
Eliminates die chilling – consistent material flow
In conventional hot forging, workpiece surface temperature drops rapidly upon contact with cooler dies. Isothermal forging maintains die and billet at identical temperatures throughout the cycle, resulting in uniform deformation, lower forming forces, and defect-free components.
Complex geometries, near-net shape
Produces thin-walled structures, high-aspect-ratio ribs, and integral components that conventional methods cannot form. Direct forging - no preforming steps.
Superior mechanical properties
Uniform grain structures, no coarse grain zones on surfaces. 2A14 aluminum achieves maximum tensile strength up to 491 MPa with elongation exceeding 12%.
Multi-material capability
We process aluminum alloys, titanium alloys, and are exploring magnesium alloys for emerging EV applications.
Near-net shape – minimal post-processing
±0.1mm dimensional accuracy as-forged. Machining required only on critical mating surfaces. Reduced material waste and cycle time.
IATF 16949-certified facility
Full PPAP Level 3 documentation available - process FMEA, control plans, capability studies - prepared to the same standard we apply to Tier 1 automotive customers.

Why Isothermal Forging
Conventional hot forging has a fundamental problem: hot billet contacting cooler dies causes rapid surface cooling, limiting material flow. Complex shapes - thin walls, high ribs - are difficult or impossible to forge conventionally.
Isothermal forging solves this. Die and workpiece at the same temperature throughout. The result:
Unrestricted material flow – fills narrow, deep cavities without premature cooling
Lower forming forces – complete filling at 10–15MN for aluminum housings
Superior microstructure – uniform fine grains deliver higher strength and reliability
Near-net shape – ±0.1mm as-forged, minimal post-machining
No preforming – many complex parts forged directly in a single operation
For complex components, difficult-to-forge materials, and applications where structural integrity is non-negotiable - isothermal forging is the production method.
