We have Merged!

In 2018 Joval Machine Company, Inc. and Lab Threads & Gear Works, Inc. merged into one company under the name Joval Machine Co.,Inc.

The History of Joval Machine Company, Inc.

JoVal’s 52-year history began when Pratt Whitney employees, Gerald Chase and Henry Siede, decided to form a partnership. They set up a machining shop in the Chase family garage and named their company JoVal, a fusion of their wives’ names: Joyce and Valerie. When the business began to thrive, the partners left their jobs behind. As full-time businessmen, they grew JoVal into a thriving company.

JoVal Machine Company formed several partnerships over the years, but today they’re a true family business. Gerald Chase is President. His son, Jeff Chase, is Vice President and some employees have been working at JoVal for over 20 years. The Chase’s believe employee loyalty, dedication, and skill are big factors in JoVal’s success.
