Effective Cooling Method for Spin Casting Process
Spin casting has been widely used in prototyping industry as a secondary process to convert a master model into a functional metal or plastic part. The main problem of the spin casting process consists in the poor thermal conductivity of silicone rubber as mold material which leads to a long cooling time between each casting processes and also to a short life time of mold. To solve this problem, different cooling methods have been developed and compared to each other experimentally. First, air cooling channel has been integrated into the spin casting mold to enhance the heat removal. Secondly, the silicone rubber has been mixed with different metal and ceramic powders to increase its thermal conductivity. The results so far prove an applicability of the developed cooling methods.
