SAVINGS OF TIME, COSTS LEADS MOLD BUILDER
GLENDALE HEIGHTS, Illinois - At Pelco Tool & Mold, a fast growing designer and builder of precision injection molds, the reasons are multiple for concentrating its purchases of mold bases on a single supplier over the past six years.
But one stands out in particular, according to Rob Suva, one of three owners of the suburban Chicago firm. The supplier of 85% of mold bases purchased by his company flamecuts the plate pockets, which leads to "a tremendous savings in time and money," he and his partners note.
Before shifting their business to Superior Die Set Corporation, Pelco employees did all milling of through pockets in all mold base plates, ranging in thickness from 7/8" to 8". A major problem, according to Rob, was plate warping - "a problem that all mold shops run into when they make the pockets themselves. Whenever you rough-machine the pockets in solid finished "A" and "B" plates from a mold base, " he notes, "the plates will inevitably warp and twist due to the normal stresses in the steel, and you lose the alignment.
"When this happens, as we previously experienced, you must press the leader pins and bushings out, re-grind the plates flat, re-jig gring the alignment holes, chrome plate the pins and bushings, then grind them to fit the new hole sizes. We had to re-schedule the plates back into the machining center to finally complete all the finishing work."
Now as a Superior customer, says Rob, "For a small charge, we get "A" and "B" plates with flamecut pockets that have only 1/16 to 1/8 inch of stock per wall. The plates are flat, and the pins and bushings are in perfect alignment for a smooth-operating mold base. We simply mill the opening to our finish sizes , and we don't worry about warping or twisting."
According to Superior's local representative Ron Deaville, of nearby Deaville & Associates, the flamecutting service - unique in the mold base industry-can save buyers $500 or more per base When compared to more costly machining prcedures offered by other suppliers. Plate warpage and hard edges , he notes are prevented by putting flame cut plates in a stress-relieving or annealing furnace prior to grinding and subsequent operations. This eliminates internal stresses of the remaining steel and allows easy finish machining for many other customers who take advantage of the service.
When a mold base is delivered from Superior,says the Pelco executive, "It's been drilled and bored with bushings and other necessary components in place. The plates move freely without any warping. All the things we previously had to do - take the mold base apart, re-grind, re-assemble - are a thing of the past."
