Tamshell Corporation was founded in 1980 by John Hernandez and Art Pierce. Having a passion for machining and dedication to manufacturing the highest quality parts, John and Art established a company that set a new standard. Quality and excellent customer service are the driving forces that grew a family-owned company from a small warehouse in Norwalk, California to the 20,000 Sq Ft State of The Art Facility located in Corona, California.

Looking Back

Looking back, manufacturing precision parts on conventional Lathes and Mills took a very skilled and steady hand with a dedication to ensuring quality.

Tamshell Today

Almost 40 years later, we continue setting the standard of precision and quality, by investing in State of The Art Machinery, and in our highly trained teams. John and Art still believe that customer service and quality parts are number one and continue to instill this in Tamshell’s culture. Here at Tashell people are what make our company great and our most valuable resource.
