Dumore Acquires Grove Die Casting 杜莫尔收购格鲁夫压铸公司


President/CEO Guillermo “Wil” Fernandez announced


Dumore Corp., Mauston, Wis., has acquired the assets of Grove Die Casting Inc., Union Grove, Wis. Now registered as Grove Die Casting LLC, the com-


pany is operating as a wholly owned subsidiary of Dumore Corporation. According to Fernandez, “the acquisition will help improve our customer responsiveness by significantly reducing lead time for our lower volume aluminum diecast components. In addition, it vertically integrates aluminum diecasting capabilities within the state of Wisconsin and moves toward minimizing or eliminating the dependence on an out-of-state or offshore diecasting supply chain for our manufactured custom DC motors and industrial tools.” Grove Die Casting LLC will continue to provide alumi-


num diecasting, targeting customers with demand for low annual volumes and up to 250,000 parts or more requiring a 600-ton capacity press or less. Dumore Corp. was established in 1913 by Louis Hamil-


ton and Chester Beach. Today, Dumore is a privately held corporation with multiple business units. Dumore Motors manufactures custom fractional horsepower DC motors, gear motors and motor assemblies. Dumore Tools provides high quality drilling, tapping and grinding tools. Dumore emergency starter solenoids, or battery contactors, for fire pump diesel engines are found worldwide. 


杜莫尔集团(威斯康辛州莫斯顿)总裁兼首席执行 官吉列尔莫•费尔南德斯宣布将收购威斯康辛州的格鲁 夫压铸公司。


格鲁夫压铸有限责任公司作为杜莫尔集团的全资子公 司运营,名称不变。费尔南德斯说:“此次收购通过显 著降低小批量铝合金压铸件的生产周期,将有助于提高 公司的客户反馈速度。此外,通过垂直整合威斯康辛州 的铝合金压铸产能,下一步将减少或消除直流电机和工 业设备等产品对本州以外或离岸压铸件供应链的依赖。 格鲁夫压铸有限责任公司将继续生产铝合金压铸 件,目标客户是小批量的年需求量小的客户,最大订单 量为 250,000件铸件或600吨产量。 杜莫尔集团由路易斯•汉密尔顿和切斯特•比奇创办 于1913年。现在,杜莫尔集团已成为拥有多个事业部 的私人控股集团。杜莫尔发动机事业部为客户提供定制 的分马力直流电机,齿轮电动机和发动机组件。杜莫尔 工具事业部生产高质量的钻孔、攻丝和磨削工具。杜莫 尔公司为柴油机消防泵生产的紧急启动螺线管(即电池 接触器)已经销往了世界各地。 


Honda, Alotech Win AFS/Metalcasting Design & Purchasing Casting Competition


本田及Alotech公司产品荣获美国铸造协会《铸件设计及采 购》杂志评选的“年度铸件奖”


Honda of America and Alotech Ltd., Cleveland, have won the 2015 American Foundry Society (AFS)/Metal Casting Design & Purchasing Magazine Casting of the Year award for their collaboration on three aluminum nodes for the Acura NSX space frame. Te ablation-case lower front body, upper front body and rear body nodes exhibit superior properties that allow them to be placed within the frame’s critical crash zones, which allowed for additional part consolidation. To safely be located in the frames crash zones, the cast parts


would have to match the properties of the surrounding extru- sions (265-295 MPa UTS, 175-205 MPa YS, > 12% elonga- tion). Consistency of properties within the crash zone is critical in establishing a repeatable crash absorption mode. Honda was able to achieve the necessary properties and additional design requirements with ablation casting by partnering with Alotech Limited, Cleveland, Ohio. Ablation casting is a new technol- ogy invented by Alotech that combines the complete flexibility of traditional sand casting techniques with rapid cooling of the molten alloy through the use of a water-soluble binder.

本田(美国)公司和克利夫兰的Alotech公司合作为 Acura NSX 车型立体构架生产的3项铝合金结构件,荣 获2015年美国铸造协会(AFS)《铸件设计及采购》杂 志评选的“年度铸件奖”。3项铸件是:缓冲壳体前方 的下支架,前方上支架和后支架,都具有优越的性能, 使之可以装在构架的关键碰撞区内,这样,碰撞区内还 可以装设其他部件。


为了安全地置于构架的碰撞区内,铸件的力学性能必 须与周边的挤压件相适应(抗拉强度265-295 Mpa, 屈服强度175-205 Mpa,伸长率> 12%)。碰撞区内 的性能一致对于建立可重复的碰撞吸收模式很关键。通 过与俄亥俄州克利夫兰的Alotech有限公司的合作,本 田公司能使其缓冲铸件具有必要的性能及额外的设计要 求。缓冲铸件是Alotech公司的一项创新技术,将非常 灵活的传统砂铸工艺和采用水溶性粘结剂使金属液快速 冷却结合起来。
