Happiness Tech LLC

Precision machine design and build company.

A multi-disciplinary engineering company where technology and craftsmanship join forces to build the success of our customers. 

We thrive on challenges of mechanism design, precision positioning, heat transfer, fluid dynamics, thermal stability, manufacturability, cost reduction and failure analysis.

We employ years of SolidWorks experience with photo rendering and animation to produce world class graphics and presentation materials, shop and inspection friendly drawings.

We provide training in Precision Mechanics and SolidWorks disciplines.



  • Precision Mechanics - Stability and position control to the smallest scales.  Understanding and applying the concepts of kinematic stability to provide precisely constrained mechanisms that are stable with time and temperature.
  • Machine Design - machines and mechanisms with robust design to go the distance in durability and be economical to manufacture.
  • FEA - Using modern Finite Element Analysis tools to speed design and optimize results provides faster product creation times and lower cost products.
  • Precision Sheet Metal Design - A great design medium for collecting design features into fewer less expensive parts.
  • ANSI Y14.5 standard compliant GD&T drawings and tolerance schemes to meet the most demanding tolerancing and fit requirements while conserving lowest part price.
