Aluminum and Zinc Die Casting
and Value-Added Services Since 1972

Company History

Pinnacle Manufacturing Company, Inc. was formed in 1972 as a secondary operation supplier of zinc die castings. Since purchasing our first zinc machine in 1975, Pinnacle has developed a sterling reputation as an innovative zinc and aluminum die caster specializing in external cast threads and multiple cored casting holes.

Since our foundation over four decades ago, Pinnacle has grown in both size and stature, currently occupying a 40,000 square foot, manufacturing facility in Batavia, New York (Exit 48 off the New York State Thruway).  As proud as we are of our mechanical innovations, we take even more pride in our employees who bring integrity, personal attention and dedicated work ethic to every customer, on every job.

A true family endeavor from its inception, Pinnacle Manufacturing was founded by Henry Kisiel. Henry’s daughter, Diana Kisiel Kastenbaum, retired as president of the company in 2023.
