Title
Thermoplastic vacuum casting - A technique for rapid prototyping of ceramics
Abstract
In contrast to conventional low pressure injection moulding (LPIM), thermoplastic vacuum casting uses silicon rubber moulds. Silicon rubber is an elastic material which allows to shape components with complicated unter cuts. Another advantage compared to LPIM is the fact that significantly larger components can be manufactored, because the slip does not solidify prematurely in the heated rubber mould during filling. By using a method of centrifugal casting large-volume components can be fabricated to near net shape dimensions without limiting the outer contour's complexity. Fine structures, thin walls and high aspect rations can also be realised. The method is advantageous particularly for the development of prototypes and the manufactoring of small quantities of ceramic components.
