Sand casting aluminium for complex shapes

A Norse Precision Castings product story
Edited by the Engineeringtalk editorial team Apr 10, 2006

Panel and enclosure design provided by sand casting a fast supply of finished parts enabling the formation of complex 3D shapes with tolerances of +/-0.4mm and wall thickness down to 3mm.

Aluminium has good temperature stability and fluidity characteristics at casting enabling the formation of complex 3D shapes with tolerances of +/-0.4mm and wall thickness down to 3mm.

Such characteristics enable front panels of enclosures to contain the necessary control and instrumentation components without sacrificing style nor functionality.

Norse Precision Castings can provide panel and enclosure design by sand casting a fast supply of finished parts.

Sand casting also provides economic prototypes with the advantage in the early stages that design changes to prototypes are relatively easily accommodated at low cost.

On back panels, aluminium can add strength, dissipate heat, or both, without an excessive weight penalty and at little extra cost than the additional material.

Mounting pads and contact pads to conduct heat away can be cast in while inserts such as threads can be set into the material without difficulty.

Specialising in such complex shapes, including thin wall casting, the key lies in the pattern making and the ability to produce near net shape, while post-cast machining can if necessary finish to higher accuracies.

With control of all manufacturing processes under one roof, Norse can manage short lead times.

Quality control also benefits from having all post-casting manufacturing, including straightening, heat treating, CNC machining, finishing and assembly, under one roof.
