Versatile Subcontract Precision Machine Shop

Preci-Manufacturing Inc. was founded by Marcel Grunvald in 1978 to provide dedicated subcontract precision manufacturing services to the computer, medical and aerospace industries. From the beginning, we've been focused on continually developing the skills and resources of our team to enable them to deliver the widest possible range of precision parts and components. We pride ourselves on our investment in and use of the latest technologies and machining processes, and we are committed to outstanding quality. As evidence of this commitment to quality, we are both AS9100D:2016 and ISO9001:2015 certified.

The Next Generation of Service

In 2017, Lloyd and Jeff Grunvald assumed control of Preci-Manufacturing. Determined to build on their father's legacy, these 2nd generation owners have been focused on pushing the limits of Preci's capabilities, seeking to grow the business in the aerospace, medical, defense and optoelectronics industries.

To realize their new vision, Preci continues to stand by the principles and philosophies that have successfully brought them through nearly a half century: investing in cutting-edge technologies, investigating advanced machining techniques and challenging themselves with ever more exacting product requirements.
