Vacuum Casting vs Injection Molding vs CNC Best Low Volume Manufacturing Method Compared
Low volume manufacturing sits in a challenging space between prototype quantities and full-scale production. When you need 20, 50, or 200 parts, the economics shift dramatically compared to single-unit prototyping or mass production runs. Understanding which process delivers the best value at which quantity range can save your project significant time and budget. Vacuum casting uses a silicone mold created from a master pattern to produce polyurethane copies. The process handles complex geometries and surface finishes that rival injection molding, with typical lead times of 10-15 days for the first parts. Per-unit costs are moderate, and the technology excels for…
