A Family Legacy of Precision
For over 60 years, R.L. Zeider has been a cornerstone of Southern California's manufacturing community — combining old-world craftsmanship with cutting-edge technology.
Small shop. Serious capability.
Founded in 1960 by R.L. Zeider, what began as a small family-owned machine shop in Southern California has grown into a capable precision manufacturing shop in Camarillo, serving aerospace, medical, and industrial clients nationwide.
Three generations of the Zeider family have maintained the same commitment to quality, responsiveness, and customer relationships that built the company. We combine that heritage with the latest CNC technology, EDM systems, and quality management processes.
Every part that leaves our floor carries the Zeider name — and the family's promise of precision.
Six Decades of Precision Manufacturing
Since 1960, R.L. Zeider has been a small, family-owned shop combining old-world craftsmanship with modern technology — proud of what we build and the relationships behind it.
The Founding
R.L. Zeider establishes a small family-owned machine shop in Southern California, laying the groundwork for decades of precision manufacturing.
Engraved Metal Heritage
Building on earlier metalworking traditions, the company begins producing engraved metal products — from jewelry and nameplates to custom-designed components — a craft refined over 70+ years.
Expanding Capabilities
Investment in CNC milling, CNC turning, and EDM technology allows the shop to take on increasingly complex aerospace, medical, and industrial work under one roof.
Quality Systems
Implementation of formal quality management and inspection processes positions R.L. Zeider as a trusted partner for demanding customers with tight tolerance requirements.
Three Generations Strong
Now a capable, family-owned precision manufacturing shop in Camarillo, CA, R.L. Zeider combines 60+ years of craftsmanship with modern CNC and EDM systems — still family-owned, still made in the USA.
R.L. Zeider, Inc. is a manufacturing company fully made in the USA. For over 60 years, we have helped customers solve difficult manufacturing challenges by combining multiple processes under one roof — CNC milling, turning, wire EDM, sinker EDM, forming, and more — keeping the majority of operations in-house to maintain control over quality, lead times, and communication.
