Proof-of-Concept Machines

Accelerate your new product introduction to the market. From simple to complex processes, we design and build prototype machines to advance your innovative manufacturing needs. We take the time to understand every detail and requirement from you to build a state-of-the-art prototype machine, normally within 8–12 weeks. Our machines are capable of testing multiple processes–so you can easily determine the best mechanism for your commercial production. Full documentation and troubleshooting expertise are included. Impress your clients, partners and future investors with aesthetically sound machines that instantly advance the speed, safety, and productivity in your demanding workplace.

Flexible Systems

With our rapid prototyping, your organization and partners have a chance to see firsthand how your concepts truly perform. We build prototype machines capable of testing 2 or 3 alternative mechanical processes. You’ll have the measurable results you need, plus full evaluation of each mechanical process, to improve every step of your product development for commercialization. Save time, resources, and gain insightful knowledge about your unique, ideal process before you transition to a complete production setup.

Prototype machines reduce tedious, time-consuming processes while improving and producing consistent results. (Think about multiplying production, employee fatigue and injury) These critical benefits of a prototype machine will rapidly accelerate your time to market. At Nexus, we have more than 20 years of prototyping expertise and a fully equipped manufacturing facility onsite dedicated to the design and build of your exclusive prototype. Devote your valuable time your next big project, and avoid internal bureaucracy, while we handle all of your prototyping needs to get the results your company and partners demand.


Your team’s outcome and prototype success depend on uniform results and sustained performance. To ensure your process endures, remains failsafe, and reliable, we use only the highest quality parts and components – inside and out. During our machine design phase, we’re deeply thoughtful not just about the engineering but also about your machine’s longevity and looks. We incorporate appealing design aesthetics because we believe it’s vital to your success. Imagine investors interested in seeing your process, how your product is made, or clients visiting your facility. Industry leaders entrust us to automate their most inventive ideas because we go above and beyond.

Client Testimonials

Sandeep and his impressive team bring together a rare set of skills and have proven themselves time and again for our group at Tesla. We’ve worked with Nexus Automation for design and machining work on numerous occasions and they’ve always met our deadlines. Their process has been seamless. I like working with Sandeep because he carefully listens to our requirements and goes out of his way to offer the best solutions/consultations no matter how busy he is. Our communications have always been honest and transparent, and I find Sandeep a pleasure to work with.

I’m thoroughly impressed by Nexus Automation’s efficiency and quality work. We hired Nexus for a project that involved unique, complex details requiring attention to detail to tedious work — and we were impressed by the ease with which Sandeep and his team handled it all. Nexus Automation was able to accommodate our fluid schedule and completed the work ahead of schedule. Nexus team proved to us that they are more than capable of handling a project, start to finish, for high-profile, highly scrutinized industry-leading client.

Sandeep (Nexus Automation) has provided support for numerous fast-paced projects of various sizes over the past year and half for me and my team, ranging from custom part manufacture to build-to-print systems to mechanical design. I have been able to rely on him and his team to deliver on time, and he has been able to accommodate any changes with ease. I’m continually impressed by his dedication and involvement – whenever unexpected issues come up, he steps in to quickly fight fires and solve problems. I truly enjoy working with Sandeep due to his humor, humility, and insight.

Sandeep helped take conceptual drawings and models of our combined cell-isolation liquid-handler prototype to a fully-designed, working medical instrument. Sandeep and his experienced team of engineers and machinists were able to fabricate this machine in an incredibly fast 8-week time period! During the design process, Sandeep was always available to provide feedback and recommendations on our evolving design and was more than happy to make changes on the fly. I would recommend Sandeep and his team to anyone looking to design and automate their machine.

Great work with the layout, set-up, staffing, and thinning out of old materials. The business feels much more organized, and the location much cleaner. By the way, the system was a big hit today in its management debut. Lots of ‘oohs’ and ‘aahs’.

Greg F

I really enjoy working with Sandeep. He is a super nice guy with no hidden agenda which makes working with him very easy. He is an honorable man that I trust. I highly recommend working with him and endorse him as a customer and business partner.
