Our Design Capabilities

Application Engineering – Need consultation on your design? Our team of application engineers are ready to help you determine the right part for your design. With decades of experience of working with the world’s largest technical and performance brands, we’re eager to solve complex problems with you.

Customer Innovation Center – We enjoy working with customers on complex projects. In fact, we’ve dedicated an entire facility to it. Want to join us for various lab testing and engineering consultation sessions? Visit our Customer Innovation Center in Connecticut to develop a solution for your unique application.

Rapid Prototyping Cell – Trying to determine the feasibility of your design as fast as possible? Use our rapid prototyping cell to turn around prototypes in as little as 2 weeks. Our engineers will work with equipment similar to our manufacturing facility to provide you with a manufacturable, economical design.

Additive Manufacturing – If you’re looking for the most uniform porosity or a non-traditional design, look no further than working with our porous 3D printing team. We can create controlled porosity designs with various density gradients in non-traditional shapes to satisfy the most unique design request. Our technology allows us to print parts with both solid and porous in a single print cycle.

Relevant Services

Lab Testing – If you need data packages or feasibility testing for your part prior to installation, we’re happy to work with you. We’ll use our lab center to perform various characterization and performance tests to ensure your parts are meeting strict specifications.

Computational Fluid Dynamics – If you would like to model your process fluids interaction with a Mott part, ask your Mott representative how we can use CFD software.

Engineering Memberships – If you’re constantly working on complex designs that require the highest standards of engineering support, ask about our membership rates, which allow you discounted rates to various lab testing, prototyping, and engineering resources.
