Prototype casting

Make your designs a reality


Are you in the business of creating new products? Aluminum prototype castings are an ideal way to make your designs a reality. Aluminum is lightweight and strong, making it great for testing and validating your designs. It's also incredibly versatile, allowing you to create complex shapes with intricate details that perfectly reflect your design intent. Best of all, aluminum prototype castings are resistant to corrosion and can withstand many environmental conditions so you know your product will be durable and reliable. Aluminum allows you to quickly iterate and refine your designs which saves time and money in the long run. With aluminum prototype castings, you can have confidence knowing that your product has been thoroughly tested and validated.


At Rapid Cast, superior quality sand castings with quick execution is our mission. No matter what you’re looking for - aluminum prototype castings or low volume castings, we’re committed to bringing you exactly what you need, when you need it. Our customers love working with our foundry because we produce the highest quality precision sand castings with an exceptionally fast turnaround, right here in the USA.

Case Study: quality controlled

A prototype order could consist of hundreds of parts. Large or small, we hand inspect every part of every order before shipping to the customer. This ensures defects are caught before they go to the customer, saving precious time spent working on scrap parts.

Case Study: Zero to 60 mph!

Our customer had a vision and needed parts as soon as possible. We were able to turn this around in record time by going from "zero to 60" – through skipping the hard tooling phase, we 3D-printed the molds for these performance racing prototypes and produced their castings in only two weeks!

Each of these parts requires nine cores to complete the mold. Using a combination of traditional cores and 3D-printed sand, we are able to make dozens of these complex parts where others had failed. Working quickly and efficiently to get the job done, our mold assembly team was able to put these molds together just like a puzzle!
