Manufacturing Facilities

ESCO is not a deceptive on-line persona. We're the real thing! Our process begins with an idea presented to our design team. Artwork is created and approved, then passed along to die and tool makers, who then craft a custom die, mold, tool or template that will ultimately be used to stamp, cast, form or mark custom products.Then, on to production, using many types of machinery; including hydraulics, automatic trimmers, lasering, engraving, etching, blasting and tumbling. Highly skilled artisans set gemstones and apply finishing touches by hand. All pieces are rigorously inspected before leaving our facility.


Made in the U.S.A.

ESCO made products are designed and manufactured by skilled craftsmen in our ever expanding facilities. Design and creativity along with the ability to directly control quality, construction and production are the essential cornerstones that built ESCO and will continue to define us. American manufacturing, the backbone of this country, is instilled in the ESCO culture and we labor with a relentless fervor to bring products of unsurpassed quality to our discerning customers.
