Dean Group International Ltd, formerly Manchester Investment Castings, is a family owned company based in Manchester, where we have automated manufacturing facilities for the investment casting (lost wax) process. To continue providing our customers with cost effective service, since 2001 we have been developing supply partnerships with China and have expanded to encompass sand casting, die casting, commercial grade investment casting, forging, and additional processes including machining, heat treatment, plating and polishing, assembly and fabrications.

DGI and our supply partners are ISO or TS accredited and as part of our service we offer stocking facilities to ensure continuity of supply with full visual, dimensional and chemical analysis at our supplier, which is repeated here in Manchester.

Other Services
We also provide design and product development support using our 3D CAD software and bespoke casting simulation package to ensure the highest quality standards are maintained.

Why DGI?
We have 40 years of manufacturing experience and possess professional family business values which make us ready to go that extra mile for our customers. We have been able to offer significant savings in both component and tooling costs whilst maintaining the quality levels and service that have been the basis for the success of DGI since 1972.
