Grimm Brothers is a family-owned business that began in the early 1980s when farmers Kent and Curt Grimm started doing side projects in their shop.
One of their first projects was creating electronics cabinets out of fabricated particle board covered with plastic laminate. Orders for the products grew rapidly—to a point that the brothers could hardly keep up with demand.
In May 1985, Kent and Curt attended the National Plastic Expo held in Chicago where they talked their cabinet buyer into replacing the current cabinet with plastic ones. The brothers believed there were opportunities in pressure forming, and decided to start a full-time business. Grimm Brothers’ first machine was a vacuum former, but, using their engineering skills, Kent and Curt subsequently retrofitted the equipment as a pressure former.
There was no looking back. Nearly 30 years later, Grimm Brothers has grown to become a leading thermoforming company—creating high quality components used in the biotechnology, automotive, aerospace, oil & gas, optical, mining, chemical, telecommunications, electronics, medical, and heavy equipment industries.
