Prototype & R&D Support
From Concept to Functional Parts—Fast
At Excell, we understand the pace and pressure of product development. Whether you’re iterating designs, testing form and fit, or validating function, our prototype and R&D services are built for agility and precision. We provide fast, flexible support to engineering teams across industries—delivering high-quality prototypes with real production intent.
With sheet metal, CNC machining, welding, waterjet, and assembly all under one roof, we eliminate the delays and disconnects that come with managing multiple vendors. We respond quickly, adapt on the fly, and help you move from prototype to production without missing a step.
What Our Prototype Services Include
- Rapid Machining & Fabrication
Fast-turn CNC milling, turning, sheet metal, laser and waterjet work—optimized for one-offs and small batches. - Iterative Prototyping
Build, test, revise, repeat. We help refine parts across multiple versions with consistent quality and responsive support. - Mixed Process Builds
Combine machining, forming, welding, and assembly into complete, functional prototypes that reflect real-world use. - Design Validation & Test Fit
Prototype for functionality, stack-up tolerance, manufacturability, and downstream integration. - Material & Method Exploration
Try different materials or fabrication methods early in the cycle to determine the best fit for performance, cost, and scale. - Design input as required
Our engineers are glad to provide input from the manufacturing point of view to help optimize your design.
We offer rapid quoting and shortened lead times to keep your development cycle on track. Our experienced team is skilled at troubleshooting and problem-solving in real time, helping you overcome design challenges quickly. We welcome single-part orders with no minimum quantities, making us ideal for early-stage prototypes. With a proven track record of supporting tight deadlines and critical design reviews, we ensure your project stays on schedule. And when you’re ready to scale, we provide a seamless transition from prototype to production—all handled in-house.
