What is investment casting? In this episode I discuss what it is and how it is used by Whitley Tune to produce high end bespoke car parts particularly intake manifolds. The traditional method of investment casting uses a die mould that is injected with wax. That wax profile is then dipped in a ceramic slurry and dusted with stucco to build a ceramic shell. The shell is built up a number of times until the shell has sufficient integrity to hold the molten metal. Whitely Tune uses a different method where by a sprue of the part is prepared in CAD and 3D printed using a bioplastic PLA. The sprue is suspended and cast into plaster. The sprue is then removed in a furnace leaving a mould ready for casting.
