Precision Group Milestones

Precision Group has grown to include multiple molding and tooling sites. There have been many changes and improvements through the years. Below are some of the milestones we celebrate remembering our hard-earned path to success.


Our company was founded by Naum and Maya Royberg in their garage in San Antonio, Texas. They saw a need, had a vision, and the first of three facilities under the umbrella of Precision Group was established – back then, called Precision Mold and Tool


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.


The owners expanded their operations and established a Precision Mold & Tool South facility in La Feria, Texas with Abe Pena at the helm.


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..


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.


An in-house molding division was created to allow clients to see a product from conception to packaging. The convenience of a one stop-shop.


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