The 3-spoke connector at the heart of Oslin's design is cast in solid brass using a unique moulding version of the Lost-Wax process. The design utilises this process to achieve the strength and precision required to support the systemised design.
A soluble core (orange wax) is first produced allowing for complex internal features to be created. A second master die wax is then injected over the core which is later dissolved away leaving the completed wax pattern. The wax is cast in a plaster mould with a vacuum assist, drawing the liquid metal into every cavity. This specialist process produces a component with dimensional accuracy and a high-quality surface finish.
