Type Measurement
Hole to Hole ± 0.005 inches
Edge to Hole ± 0.008 inches
Fold to Hole ± 0.010 inches
Edge to Edge ± 0.008 inches
Fold to Edge ± 0.010 inches
Fold to Fold ± 0.015 inches
Hole Size ± 0.003 inches
Angularity ± 1 degree

Does Wesgar supply raw copper stock?

No. We reserve our copper inventory exclusively for our partners. This ensures a stable, reliable supply chain for the specialized fabrication services we provide.

By prioritizing material availability for active projects, we help our partners avoid delays, reduce risk, and maintain confidence that their parts will be delivered on time and to the highest quality standards.

Does Wesgar provide prototypes?

Yes. We can produce prototypes in-house as a part of our design for manufacturability (DfM) process, which reduces your product development risks and shortens lead times.

Does Wesgar develop 2D drawings from concepts?

Although we do not design parts from scratch, our design for manufacturability (DfM) process supports partners on a technical level for concepts, and we can collaborate determine the best solutions for your busbar requirements.

DfM evaluates the feasibility of your busbars requirements to identify optimal cost and production efficiencies.

Does Wesgar provide other services?

Yes. We have over 60 years of expertise in high-mix, variable-volume production of end-to-end custom sheet metal and copper bus bar fabrication and machining.
