Mechanical Assembly

Keystone assembles complex box builds, sub-assemblies, and unique components at our state-of-the-art facility, adhering to ISO9001:2015 standards. Parts are tracked using barcoded work orders ensuring 100% traceability of materials and parts from vendors.

Design for Manufacturability (DFM)

Because efficient production assemblies – and fast time to market – are based on part design, Keystone works with your engineering team to review designs before beginning production. 

With a keen eye for catching tolerance stack-ups, we ensure your complex box-builds and multi-part sub-assemblies have zero gaps, misalignments, or other issues. Our Team can suggest design changes to improve manufacturing processes that lower costs and reduce delivery time.
