This article provides a detailed comparison of injection molding and casting methods, focusing on their speed implications for rapid prototyping and production. It highlights that for initial small batches (20-50 units) and design iterations, casting (e.g., vacuum casting) is faster due to quicker, less expensive silicone mold fabrication (5-7 days). Conversely, injection molding, despite its longer initial tooling time (weeks to months), becomes faster for pilot runs (hundreds to thousands) and high-volume production due to its rapid per-part cycle times (seconds). The article emphasizes that the optimal choice depends on project volume, design stability, and urgency for initial parts, with KAIAO Rapid Manufacturing offering both services to meet diverse needs.
