Product development DesigN and Fabrication

Johnston engineering is the region’s best product development engineering company.  We design your product and numerically simulate how it will perform before parts are ever manufactured. Integrating design and analysis ensures the quickest product development cycle and least number of prototype iterations which saves our customers time and money.  We fabricate and deliver your product in a timely manner and at a competitive price. 

We serve a broad range of clients in the biomedical, renewable energy, consumer product, pumped fluid systems, HVAC, thermal management, manufacturing, food handling equipment, firearms and energy storage fields.

We handle all phases of the design cycle from concept to finished product.  We will manage your project design, schedule, budget, fabrication and test.  We partner with local electrical engineers for circuit board design and software development for integrated electrical-mechanical devices.  

Our core analysis competencies include system engineering of fluid flow systems, thermodynamics, heat transfer, and component and assembly structural analysis using the latest Finite Element Analysis and Computational Fluid Dynamics design packages.
