HSI is a family owned business that was founded in 1972. Our 75,000 square foot facility is located in Buffalo, MN. We started as a metal stamping company but have expanded our capabilities to include machining, laser cutting, swiss machining, assembly, and much more! Due to our exceptional customer service, competitive pricing, and 99.7% on time delivery, we are still serving some of the same customers as we did in 1972. We pride ourselves on building strong relationships with our customers.
