Choosing between vacuum casting and low volume injection molding depends on your specific needs for small batch production. Vacuum casting has a lower initial cost and allows for easier design changes. On the other hand, low volume injection molding produces parts faster and offers a lower cost per part when producing larger quantities. The table below highlights the key differences: FeatureVacuum CastingLow Volume Injection MoldingSetup CostLow to moderateHigher upfrontPer-Unit CostHigher at scaleLower with volumeLead TimeShorterLonger setup, faster cyclesTool LifeUp to 200 partsUp to 50,000 shots Key Takeaways Vacuum casting works well for small groups and fast samples. It costs less to begin and lets you change designs easily. Low volume injection molding is good for bigger batches. It gives better accuracy, stronger pieces, and cheaper parts when you make more. Silicone molds in vacuum casting last for 20 to 50 pieces. Metal molds in injection molding can make thousands of…
