Build and Verify

DISHER’s cross-functional engineering team integrated with our client’s team to solve several challenges together. Specifically, DISHER worked on the folding and track-deploy kinematics, materials evaluation, powertrain assembly and housing design, casting design, structural FEA and simulation, prototype builds. We also worked with our client to determine the most efficient manufacturing and assembly-line processes. We continue to do value analysis work to reduce costs while maintaining quality.
