Are you designing a new part that demands precision and detail? Vacuum casting is a good choice for quickly producing high-quality prototypes for small production runs. This method allows you to test and validate your design in real-world conditions without the significant time and cost associated with traditional manufacturing techniques.
Whether you're a product designer or engineer, partnering with a trusted vacuum casting specialist can help you achieve your goals. It’s also important to understand the process and benefits of vacuum casting so that you can make informed decisions and accelerate your product development timeline.
Steps to create the parts
Also known as urethane casting or cast urethanes, vacuum casting uses a vacuum to draw liquid resin into a custom mold. This allows the production of highly detailed and precise parts—often much faster than traditional methods. While it might sound similar to injection molding, vacuum casting is specifically designed for low-volume prototypes and end-use parts.
Here's a breakdown of the key steps involved in creating cast urethane parts:
· A precise master model is created using techniques like CNC machining or 3D printing.
· The master model is encased in liquid silicone rubber, which is then placed in a vacuum chamber to cure.
· Once cured, the master model is removed, leaving a detailed silicone mold ready for casting.
· Liquid urethane resin is poured into the mold and cured under vacuum conditions to ensure accurate replication of the master model's details.
· After curing, the finished cast urethane part is removed from the mold. The mold can then be reused for additional production runs.
Good for small production runs
A high-quality silicone mold created through vacuum casting can typically produce around 30 identical parts, each with exceptional detail and accuracy. This efficient and rapid manufacturing process is suitable for quickly producing consistent parts in small-scale production runs.
