Warrensville Heights, Ohio — For Diversified Mold & Castings, the first word — diversified — tells a lot of the story.
The company, now in its third generation of family ownership, makes tooling for rotational molding and thermoforming using three processes: CNC, cast aluminum and fabricated molds.
"That's kind of what differentiates us from some of the other mold builders out there, is we can truly do all three processes in-house. And we've been casting metal for the life of the company, which is 79-plus years," CEO Vince Costello said.
Diversified Mold & Castings hosted a factory tour June 6 for attendees of the Society of Plastics Engineers' Rotational Molding Conference in Cleveland.
Costello's grandfather, Luke Beinke, started the company in 1939 as Plaster Process. It was a foundry that made cast aluminum tools in plaster. After Beinke's unexpected death in 1965, his son-in-law — and Vince Costello's father — Sam Costello took over the family-run business and bought it the following year. He got into sand casting.
Vince Costello bought it from his father in 1996. When he began working there full time in 1993, he was employee No. 6. He moved the company into full tool building. In the late 1990s. Vince brought in a partner, Randy Johnson, and his tooling company, John-Del. In 2007, Costello bought the full business and began the merging processes.
