Patternmaking & Coremaking
New patterns or modifications to existing patterns can be carried out at our in-house pattern shop or using one of our approved patternmakers. All patterns undergo a full dimensional check to the latest revision of your drawing and a report can be provided. Our new core-blowing platforms with their new generation gassing technique produces cores of a superb surface finish, excellent adherence to geometric tolerances, and very high strength resulting in castings with tighter tolerances.
Moulds are produced using industry leading air-set sand technology (chemically bonded/no-bake). Castings are manufactured at J T Price, our Sand Casting Centre of Excellence in Stoke-on-Trent. Defense standard materials routinely offered are copper based DEF STAN 02-747 Parts 2 and 4 as well as Cupro-Nickel-Chrome (CNC) DEF STAN 02-824. Components can be produced from under 1 kg to approximately 7 tonnes in weight.
Full NDT and certification is managed by our ISO 9001 certified Quality Assurance centre and relevant documents provided. This ensures full traceability from start to finish.Click here for more info on specific tests offered, including third party witness testing.
