Utilizing the latest CAD and solid modeling software and CNC Laser cutting and Turret punch tooling enables us to be a full-service shop, able to meet critical turnarounds on small run and prototypes -or- to run large production jobs for our customers.

We offer MIG, TIG and spot welding, a complete paint shop and silkscreening, assembly and full contract manufacturing services, including vendor inventory management to help customers "lean" production, reduce cycle-times and preserve capital.
