"A scientist discovers that which exists. An engineer creates that which never was."

Theodore Von Karman

New Product Development

Proof Engineering offers a broad range of engineering services to support all aspects of product development. We specialize in designs that require multidisciplinary engineering analysis, mechanical system and component level design, compliance to FMVSS and building codes, weight and cost reduction optimization, prototype builds, and test and launch. We can design discrete components, sub-assemblies, mechanisms, and full product assemblies. Our flexibility allows us to execute projects on reduced budgets and compressed timing while maintaining high quality standards.


At Proof Engineering we understand that many products must balance form and function. For this reason, we work closely with industrial design companies when aesthetics and ergonomics are key to selling your product. Industrial design support may also help you to narrow your focus through market research, helping you to understand customer’s wants and needs.


The team at Proof Engineering has the experience and design capabilities to bring a variety of products to life. We are here to assist clients from the initial conceptual stages of an idea, through prototype development, and onto production. Our engineering staff takes the time to work with every client to create an effective and efficient design. From single components to full-scale structures, there are no limitations to what our engineering team can provide. Proof Engineering has the skill and determination to take your innovative idea

and transform it into a finished product.

Supplier Sourcing and Recommendation

Finding the ideal supplier and vendor for a new product is indispensable for successful launch. When unfamiliar with a process, sourcing a company that has the expertise, reliability, and track record of delivering can be a daunting task. Under these circumstances, it is recommended to allow experts find the best-suited supplier to match your needs. As designers and producers of new products, the engineers at Proof Engineering have extensive knowledge to determine the right supplier for the job. We are able to pull from our vast database of reputable sources and also evaluate new suppliers for unique applications.
