When a manufacturer of HVAC equipment was suddenly confronted with the reality that they could no longer procure required parts from their current expanded polystyrene molder, they had a real dilemma. Fortunately, the manufacturer turned to Robin II, a custom molder and fabricator of EPS. Robin II examined the customer’s component drawings and existing tooling and was able to retrofit the mold, produce samples, and—once approved—begin production of the components for the heat exchangers’ molded foam interior. Since most of the tooling was made from cast aluminum, the job required a large precision mold which was CNC machined and had little draft or taper. The mold was extremely complex, with multiple cavities and “windows” on nearly every surface, which required hand extraction at the end of each cycle. Made from 4 pcf density virgin EPS, the final dimensions were 24.5″ x 22.5″ x 18.5″. Built to customer specifications and customer-supplied drawings and tooling, the complicated foam interiors undergo 100 percent visual inspection prior to delivery.
