Silicon Mould/Vacuum casting is a low-cost but reliable method for making a small number of high-quality prototypes based on a master model.                     Advantages: There is a low initial cost since it doesn't require investment in tooling The high fidelity of the mold gives excellent surface details requiring little or no post-processing Many different molding polymers are available that can be pigmented to meet your color requirements Molds can be ready in a few days once the master model has been created It is an excellent option for testing multiple variations of a prototype design for rapid product development
