Cast, Forged & Machined Components — Built to Your Print or Engineered to Your Operating Conditions
Two ways to work with us: send a drawing, or describe the operating conditions the part must survive. Aluminium smelting, mining, heavy construction and off-highway applications.

Delivered to customers across multiple regions · NDA & IP protection compliant · Manufactured strictly against buyer-provided documentation
Supplied under our own brand and through OEM build-to-print programmes, under confidentiality agreements.
Two Ways to Start
Some buyers arrive with a completed drawing. Others arrive with a part that keeps failing. Both start here.
|
Path A · Build-to-Print You already have drawingsSend 2D drawings, 3D models, material specifications or a physical sample. We quote, tool and manufacture strictly to your documentation — no substitution, no catalogue part. |
Path B · Application-Led You have an operating problemTell us the furnace type, throughput, temperature range, cycle frequency, or how the current part fails. We engineer a component around your actual operating conditions. |
What We Deliver

Actual inspection reports are issued exclusively to the original buyer under NDA.
Built on Trust. Backed by Process.
OEM supply is not only about price. It is about consistency, traceability and protecting your intellectual property.
Traceability & Protection
Every project runs under NDA. Traceability is maintained internally through part marking and heat-number records, where applicable; report scope and documentation are set by the drawing and the applicable standard, and confirmed at order placement.

Typical Enquiries We Handle
Representative situations. Customer identities are withheld under NDA.
|
Aluminium casthouse Replacement dross pans and sow moulds to existing drawings, with material changed to extend service life in high-cycle operation. |
Secondary aluminium Dross cooling and handling equipment sized to an existing rotary furnace throughput, delivered as a matched set. |
Mineral processing Wear parts manufactured to the original equipment drawing, with material grade selected to match the duty and the observed wear pattern. |
Before You Send an Enquiry
Do you sell catalogue parts?
No. Every item is produced against buyer-provided drawings, specifications or an approved sample.
What should I include in an RFQ?
Drawings or 3D model, material specification, quantity, required tolerances, and — where relevant — the operating conditions the part must survive.
How is my drawing protected?
All technical documentation is handled under NDA. Drawings are not shared outside the manufacturing entities assigned to your programme.
What documentation is provided with the parts?
An inspection report is issued electronically for each shipment as standard. What is checked is defined by the drawing, the applicable standard and the duty the part has to perform. Heat-treatment and melting records are retained against the part marking and heat number, where marking is applicable. Material certification is supplied where the order and the applicable standard require it, and where it is available from the mill. Hard-copy documents can be supplied where required.
