One of the world's largest OEMs required Sarginsons to help improve elongation in a structurally challenging, single piece sub-frame. The work involved some component redesign but it was the use of an innovative cooling solution, to improve TYE in the sand casting, that enabled a production accurate prototype, allowing testing and avoiding expensive complications in production.
Casting is perfectly suited to combining individual components as it is the most flexible of all manufacturing techniques. This plasticity of design potential has been made real by Sarginsons unique ability to control microstructures and simulate TYE performance in prototypes. With other technological advances Sarginsons is ideally placed to exploit the trend toward incorporating multiple components into one casting.
A one piece casting replacing multiple components makes sense.
A mechanical issue with ductility, 8% required in key stress zones, in sand cast prototypes was solved with forced cooling, impacting the micro-structure, whilst the production complications of such a large component were overcome by developing multiple direct feeds, despite a compact tooling solution. Eight separate subframe components were merged, with a 30% mass reduction, with no loss of performance.
Minimising manufacturing costs and weight, whilst improving performance, demanded that every aspect of the Sarginsons technology arsenal was utilised. Digital Simulations, Topology, Metallurgy, Smart Cooling and the full gamut of Sarginsons low porosity engineering were deployed.
Rapid Iterative design made intelligent through digital simulations proved to be the fastest, most effective way to successfully merge components. This approach allowed imagination and technology to be given free rein and an optimised solution, to be found within the time constraints allowed. The component comfortably surpassed required TYE mechanical targets.
The advances in the technology of casting, particularly those pioneered by Sarginsons, facilitate different components being successfully merged into one, larger casting. A real step forward in manufacturing technology.
