While many “mono-material” blown film facilities and pipe and profile extruders have long used silos at their plants to store bulk shipments of resin, many custom injection molding operations, which may run dozens of grades of resin, have tended to stick more with gaylord-size shipments. Still, says Dier International Plastics’ president, Greg Reid, injection molders should monitor usage rates of each resin type to determine if there is a cost benefit to investing in a bulk storage system.

“Companies running lots of resin in gaylords could be running it from a silo instead and saving significant money,” says Reid.

Reid says the return on investment could be achieved in as little as a year, depending on resin usage. Savings from switching to a bulk or centralized resin storage system also arise from increased efficiency of materials handling, notes Reid.

Most materials handling equipment suppliers can assist molders in performing the calculations to determine a bulk resin storage system’s return on investment.
