Agile Resin Casting Solutions for Prototyping & Low-Volume Production
The Prototyping Paradox: Cost vs. Speed
Traditional manufacturing forces engineers into a lose-lose scenario:
- $25k+ steel molds for <100-unit batches
- 8-12 week delays for simple overmolded grips
- ±0.3mm tolerance gaps causing assembly failures
Our resin casting manufacturing powered by rapid tooling breaks this cycle through adaptive process selection:
- Silicone tooling: 3-5 days turnaround for 1-200 units
- Vacuum casting: ±0.05mm accuracy for thin-walled prototypes
- Room-temperature vulcanizing (RTV): 60% faster than CNC machining
Critical Applications: Solving Industry-Specific Bottlenecks
1. Medical Device Housings
Problem: 9-week waits for low-volume silicone molds for medical devices (ISO 10993 compliance).
Solution:
- Platinum-cure RTV tooling with <0.1% shrinkage
- USP Class VI-certified urethanes
- Ships 30-unit batches in 6 days at $38/unit
2. Automotive Lighting
Problem: $18k tooling costs for custom resin-cast automotive housings (1-50pcs).
Solution:
- Aluminum-filled epoxy master patterns
- 80 Shore A polyurethane replicates
- 50pc orders delivered in 8 days (70% cost reduction)
3. Consumer Electronics
Problem: 6-week cycles for quick-turn urethane prototypes under 20 units with IP67 seals.
Solution:
- Digital light processing (DLP) master models
- Vacuum degassed silicone tools
- 20pc batches in 4 days @ $22/unit
4. Aerospace Sensors
Problem: 11-week lead times for high-temp epoxy casting for aerospace (180°C continuous).
Solution:
- Ceramic-loaded epoxy systems
- Post-cure thermal cycling to 220°C
- 15-unit delivery: 9 days | 45% below industry pricing
Process Selection Matrix: Geometry-Driven Manufacturing
| Part Requirement | Optimal Process | Tolerance | Economical Batch | Lead Time |
|---|---|---|---|---|
| Complex undercuts | Silicone tooling + vacuum casting | ±0.08mm | 1-200 | 3-7 days |
| Thin walls (<1mm) | Pressure-assisted RTV molding | ±0.12mm | 5-100 | 2-5 days |
| Ultra-smooth surfaces (Ra 0.4µm) | Centrifugal casting | ±0.05mm | 1-50 | 4-6 days |
| Metal insert overmolding | Low-melt alloy tooling | ±0.15mm | 20-500 | 5-9 days |
