Precision Group Founded

Precision Group is founded as Precision Mold & Tool in San Antonio, TX by Naum & Maya Royberg, initially operating out of the Roybergs garage.


Moved to new space

The Roybergs moved their business into a small industrial space located within the North Park Industrial Park. As their capabilities increased with a reputation for quality components, their customer base grew.


Opened Office in La Feria

The owners expanded their operations and established a Precision Mold & Tool South facility in La Feria, Texas.


Expanded San Antonio Office

Precision Mold & Tool North expanded into a 10,000 sq. ft. facility. This allowed our company to offer even more services to the automotive industry.


Expanded San Antonio Office Again & Opened Reynosa Office

Precision Mold & Tool North expanded further to encompass 22,000 sq. ft. This allowed the company to manufacture at another level and it was a realization of the Roybergs’ dream to expand their molding capabilities. Precision Mold & Tool Mexico was strategically established in Reynosa, Tamaulipas, Mexico to enable Precision Group to serve those in the Maquiladora Industry located on the Texas-Mexican border.


Created In-House Molding Division

Precision created an in-house molding division to allow clients to see a product from conception to packaging. This one-stop-shop setup ushered in a new level of convenience for our customers.


Rebranded as Precision Group

With its multi-locations and extensive services, Precision Mold & Tool was officially renamed and rebranded as Precision Group to attract U.S. and global markets.


Attained ISO certification

Attained our ISO 13485:2016 certification for Medical Device and Quality Management Systems.
