From Sketch to Scale

We take half-formed ideas and turn them into parts that can actually be machined and used. Our product prototyping service is designed for clients who need to move fast. We handle custom part design and prototyping, taking on projects that begin with a simple sketch on paper or those that require revision to meet new regulations.

Iterative Design & Engineering

Our engineering team works directly with you to model, refine, and test parts.

CAD & FEA

We can take your concept and iterate through design and material selection, utilizing FEA Analysis to predict how the part will perform under stress.

Practical Revision

We use practical know-how rooted in real race experience to refine designs, ensuring they aren’t just theoretical, but manufacturable.

Scalable Production

We are equipped for both single-part prototypes and small batch runs. Once a prototype is validated, our shop can seamlessly transition into short-run production using our 5-axis and mill-turn capabilities. We offer quick-turn options to get your physical part in hand for fitment testing and validation as fast as possible.
