Abstract: New products must be more quickly and cheaply developed, manufactured and introduced to the market due to the pressure of global competition. This work demonstrates a technique for producing accurate wax patterns made from a high precision silicone rubber mold. Silicone rubber mold is cut into five components, which is the minimum number of components for assembling the silicone rubber mold. The advantages of this silicone rubber mold include savings in assembly time, reduction of human error while assembling the silicone rubber mold and good assembly precision. The shrinkage of critical dimensions can be controlled within 2.19%. Results reported here can speed up the velocity in the development of a new cylinder head in the motorcycle industry.
