We are adept in the design and manufacturing of extrusion mandrels, and have extensive amounts of experience in these areas.

We have the equipment and expertise to produce extrusion mandrels from 13mm diameter upwards, and up to 1.5 metres in length.

Due to the diameter to length ratio of most extrusion mandrels, distortion during machining and heat treatment are major factors.  Sterling Machining and its heat treatment subcontract companies have developed manufacturing routes to ensure minimum distortion throughout manufacture, enabling us to produce extrusion mandrels to an excellent standard at a very competitive price.
