In the rapid prototyping development of medical devices, aluminum molds have become the preferred tool for many companies. Compared to traditional steel molds, aluminum molds offer significant advantages, making them especially suitable for the strict requirements and high-iteration demands in the medical field.
First, lower cost and faster lead times: Aluminum is much easier and faster to machine than steel, shortening mold fabrication cycles to just a few days to one week (while steel molds often take several weeks). Initial costs are typically only 1/3 to 1/2 of steel molds. This enables medical prototypes to iterate and validate designs rapidly within 2–7 days, avoiding high upfront investment risks.
Second, superior thermal conductivity: Aluminum’s thermal conductivity is 4–5 times higher than steel’s, allowing faster heating and cooling, shortening molding cycles by 20–40%, and reducing defects like warping and sink marks. This ensures dimensional stability and smooth surfaces for medical parts, making it ideal for biocompatible plastics (such as PC, ABS, and medical-grade materials) in injection molding.
Additionally, lightweight and easy to modify: Aluminum molds are lighter, easier to handle, and quick to revise for design changes, perfectly aligning with the agile development process of medical products from concept to clinical validation. Although their lifespan is about 5,000–10,000 cycles (suitable for prototyping and small-batch bridge production), this is more than sufficient for the medical prototyping stage.
