Rapid Prototyping Vacuum Casting Silicone Parts For Automotive Parts
Product Description
Vacuum casting specialized prototyping method that utilizes liquid polyurethane resin injected under vacuum into flexible silicone molds to replicate intricate components. Ideal for low-volume bridge production during product development, it enables rapid iteration of functional prototypes or pre-series batches. A single high-precision silicone mold typically yields 10–30 identical copies before degradation, balancing cost efficiency with sufficient volume for design validatioThe inherent flexibility of silicone molds allows unparalleled geometric freedom, enablin reproduction of complex organic shapes (undercuts, micro-textures), capture of fine surface details (≤0.1mm resolution), casting of parts with zero draft angles or reverse tapers, seamless demolding without part damage.
Advantages
Compared to traditional tooling, this process delivers significant advantages:
1. Cost Reduction: 70–90% cheaper than metal tooling
2. Speed: Molds fabricated in 24–48 hours vs. weeks
3. Material Versatility: Simulates ABS, PP, rubber-like TPEs, or transparent resins
4. Quality: Near-injection-molded surface finishes
Common applications include automotive interior components, medical device ergonomic studies, and consumer electronics housings requiring rigorous fit-testing. By combining geometric flexibility with rapid turnaround, vacuum casting bridges the gap between 3D-printed prototypes and mass production tooling—accelerating product development cycles while minimizing financial risk.

Technical Support & Services
Crida’s engineers provide end-to-end technical partnership, starting with analysis to optimize part geometry for silicone molding—resolving undercuts, wall thickness conflicts, and venting requirements. We guide material selection from 100+ urethanes (simulating ABS, PP, rubber, or transparent resins) and execute rapid mold fabrication (24-48 hours) using industrial-grade silicones. For complex masters, we employ high-resolution 3D printing (±0.1mm) and vacuum degassing protocols to eliminate bubbles. Pre-casting validations include flow simulations to predict resin behavior and thermal management plans for uniform curing—ensuring first-time success for prototypes, bridge tooling, or low-volume batches (10-30 parts/mold).
During production, our team monitors vacuum integrity (<5 mbar), resin infusion rates, and demolding techniques to prevent defects like orange peel or air entrapment. For urgent issues—mold tears, surface flaws, or dimensional deviations—we offer 24/7 crisis support with virtual troubleshooting (<2h response) or global on-site intervention (48h dispatch). Post-casting services include CMM validation (±0.15mm), cosmetic refinishing (painting, texture matching), and functional enhancements (metal inserts, CNC machining). Clients also access certified training in mold maintenance, ISO-compliant inspection, and vacuum chamber operation—turning technical challenges into competitive advantages.
FAQ
Q: How do I get a quote?
A: Please kindly provide us 3D CAD solid model in Step, IGS, X_T format. Normally, Two-dimensional (2D) drawings are not adequate for accurate quoting or parts making.
Please tell us your requirements on quantity, surface treatment, color, material, and application environment for accurate pricing.
Q: Will Crida sign Non-Disclosure Agreements (NDA)?
A: Yes. If it gives you peace of mind to sign an NDA, we are more than willing to do so. But we have the right to keep your design confidential no matter NDA is signed or not. All factories are camera-monitored.
Q: What is Crida ‘s advantage?
A: 1. Abundant experience.
2. Having professional technology and high-accuracy prototypes
3. Top quality and competitive price.
4. Focus on customers’ needs.
Q: Why need to make a rapid prototype?
A: Prototypes allow the design team to test for functionality and ensure design and fit are correct. The prototypes can be used for sales meetings, customer presentations, and tradeshows overall time-to-market can be reduced since accuracy in design assures a streamlined project timeline.
Q: Can you provide OEM/ODM service?
A: Yes, we warmly welcome OEM orders. We accept OEM Logo & Package. For MOQ and price, please contact us.
Q: What is the production time?
A: Sample lead time is within 3 working days.
Normally, mass production time is 3-7 days ------It depends on your order quantity.
