Material R&D, casting, carbide insertion, hardfacing overlay and precision machining sit under one roof — so the insert, its parent casting and the finished tolerance are one supplier’s responsibility, not three.
We specialise in composite reinforced wear components for mining, quarrying and mineral processing. The portfolio spans high manganese steel, chromium cast iron, alloy steel and bi-metal wear solutions for chute liners, mill and metal shredder wear parts, alongside OEM/ODM customisation and on-site wear analysis. One roof, one drawing, one heat number.
Medium-frequency induction and gas-fired furnaces with on-line spectral control — chemistry is corrected at the furnace, not after the pour.
Resin sand and lost foam casting, HPM controlled cooling. Patterns are printed or machined in-house for rapid development.
1,600 t hydraulic press, CNC vertical lathes, milling and boring, shot blasting — one set-up per drawing wherever the part allows it.
Tungsten carbide and TiC insertion, plus automatic hardfacing overlay, done at the same bench as the casting.
Water toughening and quenching furnace, stress-relief furnace. Austenitising temperature is logged per heat.
Optical emission spectrometer (SPECTRO), metallographic microscope, hardness tester, ultrasonic testing and magnetic particle inspection.
| Family | Grades and forms |
|---|---|
| Conventional | Mn13 / Mn18 / Mn22 manganese steel, Cr26 high chromium iron, alloy and Ni-hard grades. |
| Composite | TiC / WC inserts cast into the wear face, bi-metal composite, hardfacing overlay, composite matrix. |
| Customised | Formulations matched to the ore’s abrasion and impact profile, not to a catalogue number. |
| Type | How it is built | Where it belongs |
|---|---|---|
| Liquid–liquid cast bi-metal | Fused high-chromium layer poured onto a manganese or alloy substrate. | Ball mills, cone crushing, heavy impact. |
| Inserted bi-metal | TiC or WC blocks set only in the high-wear zone. | HPGR studs, hard-ore crushing. |
| Hardfaced CCO bi-metal | Chromium carbide overlay on plate, for low-impact sliding abrasion. | Chutes, hoppers, transfer points. |
| Explosion-clad bi-metal | Flat panels bonded by explosive cladding. | Simple flat liner structures only. |
A liner is half the job. The other half is knowing what the machine is actually doing: how much wear face is left, what alloy is really in the chamber, and whether it is the setting or the feed that is killing it. We walk the chamber with your maintenance team, then write down what the numbers support.
On the liner, in place — not estimated from a photo.
Handheld XRF on a flat in the yard, no sample cut.
Closed-side setting and feed gradation recorded with the wear map.
Change-out plan, parts list, backing compound and fitting notes, photos.
By truck, by train, by container — loaded, lashed and photographed. Crates are marked so the heat number on the test bar still matches the plate on arrival, and every shipment leaves with its inspection record.
| In-house | What it buys you |
|---|---|
| Composite metallurgy — TiC and WC inserts | Full chain, no subcontract: melt to machined part. |
| ISO 9001 QA and NDT | Full material traceability, melt to finished goods. |
| Reverse engineering | Rapid pattern development from a worn sample. |
| Flexible supply | Stock for fast delivery; engineered to order when it is not. |
| Wear analysis | Cost per tonne of ore, not price per kilo of steel. |
