About
Mark Eberhardt is chief executive officer and sole owner of Retlaw Industries, the Hartland thermoplastic injection-molding company that began as a tool shop in 1977.
In a MoldMaking Technology feature he describes adding sampling presses and, by 1982, asking customers why Retlaw should not mold their parts as well—today moldmaking is a smaller slice beside proprietary glass-filled nylon pulley production and custom OEM work.
The same feature places Retlaw in a roughly 50,000-square-foot Hartland plant with about 40 employees and about 20 injection presses (50–720 tons), splitting business between custom jobs and a proprietary 33% glass-filled nylon pulley line sold to lawn-and-garden, conveyor, fitness, and other OEMs. Eberhardt has publicly discussed hot-runner conversions that cut scrap, shortened cycles, and moved pulley molds onto smaller presses.
LinkedIn and directory listings identify him as president and CEO in Hartland since the early 1990s. The company still manufactures from its Hartland plant, keeping the industrial owner locked to the city page and Lake Country manufacturing corridor.
