We supply high precision machined castings, in either large or small volumes.

Through continuous investment in the latest technologies we are constantly striving to stay ahead of the competition.
Aluminium and zinc high pressure casting
With machine closing forces from 60 – 1350T we are able to supply either raw or fully machined castings in a variety of alloys from 5g upwards. Temperature controlled furnaces ensure consistent melt quality. If required we are able to supply parts with various surface finishes including; anodising, plating and powder coating.

Our foundries supply to ISO9001:2008 and TS16949 standards. CMM reports, spectrograph, x-ray testing, casting simulation, hardness and roughness testing is available.

Aluminium gravity diecasting
When the volumes and surface finish expectations are lower and to avoid the sometimes high investment costs for HPDC parts can be produced in our Gravity casting plants. Parts weighing just a few grams up to 100Kg can be supplied from this process. As with our other production plants material certification, non-destructive testing and finishing operations can be included.
Steel and stainless steel castings
Using a combination of hand/ automatic moulding or permanent mould production, our foundries are able to supply parts from 5kg up to 5000kg in the following materials:-

  • Carbon Steel: WCB, WCA
  • Stainless Steel: 304, 316
  • Nickel / Cobalt and Copper Alloys

CNC machining and surface finishing can also be included

For your peace of mind our foundries can provide:-

  • 1 Material Certification
  • CMM reporting
  • PPAP, ISIR and VDA documentation
  • Non Destructive Testing
  • X-Ray / Ultrasound testing

Foundry accreditations include ISO 9001 : 2008 | LLOYDS | PED | ISO TS16949

Grey iron and nodular iron castings
Produced on latest technology automatic moulding lines, we supply Grey Iron to EN1561 EN-GJL-150, 200, 250 & 300 grades, SG Iron to EN1563 EN-GJS 400, 500, 600 & 700 grades. Other grades to customer specification can be offered. More often than not we supply fully finished parts including machining and surface finishing.
Investment castings
For parts requiring near nett shape production our investment casting foundries offer parts produced in non-ferrous materials including stainless steel, brass and aluminium. Part ranging in weight from a few grams – 80Kg can be produced depending on size. Finish machining, sub assembly and surface finishing can also be provided.
