Heat Treatment
Our Global Steel Heat Treatment division specialises in induction and flame hardening of industrial components. With capacity for shafts up to 400mm diameter and 4 metres long, we enhance material durability through precision surface hardening techniques. Our ISO 9001-certified processes include stress relieving, tempering, and through-hardening for mining, transport, and heavy industry applications.
Gearco Engineering Co Engineering Manufacturing
We produce spur, helical, bevel, and worm gears for critical industrial applications. Our capabilities include internal/external splines, racks, and custom gear solutions for mining machinery and transport systems. All components meet exacting Australian standards for performance and longevity in demanding operating environments.
Gearco Engineering Co Engineeringbox Repair
Our Seven Hills facility refurbishes industrial gearboxes up to 5 tonnes. Processes include component inspection, magnetic particle testing, bearing replacement, and comprehensive performance testing. We restore gearboxes to original specifications with oil-resistant repainting and precision reassembly for reliable operational readiness.
Shot Peening
This cold-working process improves component fatigue life through controlled surface compression. We treat gears, shafts, and critical engine parts using steel, ceramic, or glass media. Onsite Almen testing ensures compliance with customer specifications for aerospace, automotive, and industrial applications.
Mining Machine Repair
We specialise in refurbishing mining equipment including wheel units, wet brakes, and speed reducers. Our processes involve crack testing, MIG welding, and precision machining of components for Joy 155C/225C shuttle cars. We maintain exchange stocks for rapid equipment replacement and downtime minimisation.
