In Brief
The fundamental difference between a Single Cavity mold and a Multi Cavity mold lies in the number of parts the mold produces in each injection cycle. A Single Cavity mold produces one part at a time, making it cheaper to build but more expensive per part due to longer production time. It's suitable for small production runs, technically complex products, or early validation stages.
In contrast, a Multi Cavity mold produces multiple parts simultaneously (2, 4, 8, 16, or more) per cycle. The cost of building this mold is significantly higher due to engineering complexity, but it drastically reduces the per-part price and shortens delivery times. It's the ideal solution for mass production when the market demands large quantities and you want to maximize long-term margins.
