Remember sand casting for one-offs
Aluminium casting techniques at Norse Precision Castings can achieve tolerances of 0.4mm and wall thickness of 3mm, and sizes approaching one metre cube
Metals techniques used for plastics and vice-versa
Similarities of manufacture in gravity sand casting and moulding rigid polyurethane, gives a foundry the versatility to work in plastics and metals.
Gulmay Medical commenced operations in 1995 to design, manufacture and market x-ray therapy equipment and now has equipment installed in over 100 hospitals worldwide.
Their complete turnkey approach of room design, installation, acceptance testing, operator training, plus service and maintenance options has been pivotal in establishing an enviable reputation in the radio therapy equipment market.
Techniques at Norse Precision Castings allow wall thickness on rigid polyurethane from 1mm to 30mm with general tolerances as low as + 0.3mm, and on aluminium on 3mm + 0.4mm, producing parts requiring little or no secondary operations.
As illustrated with these parts however, where one piece was required to comfortably slide over two other joined parts, much closer tolerances were achieved.
Further the benefits of polyurethane come without the loss of the commercial advantage of plastic, and both benefit from low cost "tooling" made in relatively short production times.
Both materials are highly fluid at casting, giving exceptional ability to form complex three dimensional patterns to near net shape.
This excellent fluidity also allows thin walls and irregular shaped surface indentations for instrumentation, controls and logos to be incorporated into the part.
The versatility of both materials enabled designers to pay particular consideration to style and ergonomics resulting in maximum manoeuvrability and unrestricted applicator positioning for Gulmay's equipment so that the patient can adopt any position for maximum comfort throughout the treatment and operator time is kept to a minimum.
Xstrahl units can be either wall or ceiling mounted, retaining this versatility of movement even when installed into mobile transport to satellite clinics and day care centres.
