Seljan Company is a family-run plastics manufacturer based in Lake Mills, Wisconsin, founded in 1967 as a tool and die shop. It expanded into stamping with a focus on door and window hardware, and then moved into fabrication in the mid-1970s, including stainless steel swimming pool filters. That diversification later extended into food processing equipment and oil filtration, and the company now produces more than 30 shapes and sizes of tanks.

The company began in rotational molding in the early 1980s, and throughout the 1980s and 1990s it produced thousands of molds for large molders while developing its own molding capabilities. By the 1990s it had invested in its first rotational molding machine, expanding its plastics division to include injection and blow molding. Acquisition activity followed in later years, including FH Noble Company in 2002, Kolorcans in 2005, Mach 2 Tire Company in 2010, and C3 Custom Coolers in 2015; today Seljan manufactures more than 1000 plastic parts and 400 metal part numbers.
