Choosing between single and multi-cavity molds is a critical decision that dictates your project's unit cost and long-term scalability. This guide breaks down the technical and financial trade-offs to help you optimize your tooling investment for maximum ROI.

Key Highlights:

• Total Cost of Ownership: How to calculate when the higher upfront cost of multi-cavity tooling pays for itself.

• Precision & Consistency: Why single-cavity molds often win for high-tolerance medical or aerospace components.

• Lead Time vs. Volume: Balancing the speed of bridge tooling with the efficiency of high-volume production.

• Risk Management: How to mitigate "all eggs in one basket" risks in multi-cavity configurations.
