Motor End Covers
Motor end cover is a typical application of bulk molding compound (BMC) material. It replaced die cast aluminum/zinc parts by offering various advantages. By using BMC material, it can reduce part weight by 30% (compared to aluminum) and 70% (compared to zinc). Because of less weight, transportation cost is reduced as well. Secondary machining is no longer needed, neither for gate removal nor for more accurate dimensions. Total cost can be saved by 30%.
BMC material offers high accuracy and dimension stability. BMC tooling has 3-4 times longer life than die cast tooling and requires much lower maintenance/repair costs. It also allows complex design like slide cores, etc to be combined with tooling so to reduce cost again. Bearing bore, metal accessories can also be molded-in as through one step molding process. To sum up, BMC material offers the below advantages than aluminum/zinc die cast motor end covers:
*Weight reduction
*No secondary machining process needed
*Less cost, up by 30% lower
*Longer tooling life
*One step process for more complex design
*Dimensional stability
*Noise reductionBMC Insulation China
