If you want to make a few parts or test ideas, vacuum casting is fast and costs less at the start. However, if you need to make many parts, injection molding is cheaper for each part and can produce millions. When considering your options, think about factors like price, the quality of the parts, how quickly you need them, the materials you want, and the complexity of the parts.
