EVANSVILLE, IND. - Injection molders are making a new version of JBL Professional's Eon portable speaker line with a 25 percent mica-filled polypropylene under a cost and manufacturing improvement program. The audio line includes powered units, passive units, subwoofers and a portable mixer.
``We were looking for a less-costly material and an improvement in scratch resistance,'' said Mike Elliott, program manager with the JBL Professional Division of Harman International Corp. in Northridge, Calif.
``We needed cost reduction, improved performance and strict maintenance of dimensional stability,'' he said.
Ferro Corp.'s filled and reinforced plastics division makes the MPP25FU22HB copolymer at its plant in Evansville, said Randy McAllister, Ferro's western marketing development manager. The proprietary compounding technology creates a product with high-impact and low-warp characteristics.
Avedon Engineering in Long-mont, Colo., molds the 10-inch speaker enclosure and trim piece, and the Denver facility of SPM Inc., a Dynacast Co., uses about 15 pounds of the PP in molding each of the 15-inch speakers. An SPM plant in Anaheim, Calif., molds the mixer's enclosure of the same material.
The previous material cost more and did not perform as well as the Ferro product, according to Elliott.
