Frequently Asked Questions

What is precision fabrication?

Precision fabrication is the process of cutting, forming, welding, assembling, and finishing metal parts to match detailed drawings and tight dimensional requirements. For custom enclosures, it often includes laser cutting, N/C punching, press brake forming, hardware insertion, weldments, and surface preparation so the finished chassis or enclosure fits its intended application reliably.
