ADI Capability

ADI Specialists with Dedicated Capacity

Austempered Ductile Iron delivers strength comparable to low-alloy steel at the weight and cost of cast iron. Our dedicated systems handle complex, thick-section parts most foundries cannot.

  • Enhanced StrengthRivalling low-alloy Q&T steels — lighter components, no compromise
  • Superior Wear ResistanceIdeal for abrasive and sliding-contact applications
  • Fatigue ResistanceProlonged service life under cyclic loading
  • Design FreedomComplex thin-wall geometries, multiple components in one casting
  • Pre & Post MachiningFull machining expertise before and after austempering

What Sets Us Apart

UK and European buyers choose us for technical depth, vertical integration, and a genuine partner-focused approach.

01

True One-Stop Shop

Casting, machining, heat treatment, painting and full assembly — all under one roof. Fewer suppliers, simpler supply chain.

02

ADI Specialists

5,000 t/yr dedicated ADI capacity with thru-hardening up to 150mm cross-section — capability most European foundries cannot match.

03

Engineering-Led

Magmasoft simulation for casting, core and stress analysis. Defects caught in simulation — not on your production line.

04

Select Customers Only

We work with a focused group of industry-leading OEMs. You're a partner, not a number — quick decisions, flexible production.
