Speciality Automotive

Doncasters is an industry leader in the manufacture of automotive turbocharger components and automotive stud welding systems.

The Company has over 40 years’ experience with turbocharger technology and employs innovative manufacturing techniques for the production of components for both the commercial vehicle and passenger car turbo diesel markets.

The Division has manufacturing facilities in the UK and USA and is able to offer remarkably short ‘time to market’ solutions for key turbocharger OEMs such as Honeywell, BorgWarner, Holset and IHI.

Our components are manufactured to extremely demanding specifications to ensure that we meet our customers’ requirements for dimensional tolerances and mechanical properties. These specifications reflect the operating conditions of the components within the turbocharger, where wheels rotate at speeds of up to 150,000 rpm and can operate at temperatures in excess of the theoretical melting point of the alloy.
