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.Mechanical Engineerin
