Low-Volume Process Selection Matrix
Review process parameters side by side to align part requirements, engineering resin compatibility, production timelines, and budget expectations.
| Process | Low-Volume Vacuum Casting | Low-Volume Injection Molding | Low-Volume CNC Machining | Rapid Tooling |
|---|---|---|---|---|
| Material Range | Polyurethane resins simulating ABS, PP, PC, POM, and rubber (Shore 30A-90A) | Production thermoplastics: ABS, PC, Nylon (PA6/PA66), PP, POM, PEEK, TPU | Engineering stock: POM/Delrin, PEEK, PTFE, Nylon, PC, PMMA, HDPE, UHMW-PE | All commercial injection-grade resins including reinforced & flame-retardant blends |
| Manufacturing Process | SLA master pattern creation → RTV silicone mold fabrication → Vacuum polyurethane casting | High-pressure thermoplastic injection via modular mold bases and steel/aluminum inserts | Subtractive precision 3-axis, 4-axis, and 5-axis milling and turning from solid plastic billets | Simplified aluminum (Al 7075) or pre-hardened steel (P20) tooling for rapid qualification |
| Key Applications | Design verification, marketing mockups, clinical test enclosures, pre-production assemblies | Consumer electronic housings, medical device bezels, industrial sensor enclosures | Precision bushings, gear prototypes, fluidic manifolds, structural robotics brackets | Market entry batches, interim line supply during hard tool build, pilot validation runs |
| Typical Batch Quantity | 10 to 50 pieces per silicone mold | 250 to 10,000+ pieces | 1 to 500 pieces (Zero tooling) | 100 to 5,000+ pieces |
| Standard Lead Time | 5 to 10 business days | 12 to 20 business days | 3 to 7 business days | 10 to 18 business days |
