About Us

R&H Machine Products was established in 1967 by Ralph Rassi & Bob Hayes as a small family run screw machine facility based in Marcellus, Michigan. Denny Grice purchased R&H Machine Products in September 1995, and moved the company to its current location in Three Rivers, Michigan.

This move allowed R&H to triple its manufacturing space, allowing steady growth. Since then, R&H has diversified its production with modern machine tools and continued to add to its production capabilities.
