Estimated reading time: 22 分钟 You use the vacuum casting process to make exact parts from a master model. This method lets you change your design and use cheap tools. It is great for making prototypes and small batches. You get high-quality prototypes with smooth surfaces and tricky shapes. This happens because there are fewer air bubbles and you can use more materials. AdvantageDescriptionReduced Porosity and DefectsGets rid of air pockets so parts are stronger.Superior Surface FinishMakes smoother surfaces, so you do not need much extra work.Complex GeometriesLets you make detailed designs that other ways cannot do.Material VersatilityWorks with many…
