lead to a reduction in the variability in the final iron (minimizing the effect on the normal series of the worker operations) and reduce internal scrap rate. Because vari- ability increases costs to address scrap issues, the Melt- Deck system has the potential to: • Minimize the use of corrective materials. • Save energy by eliminating overheating in melting furnaces and allowing, in some cases, a reduction of the pouring temperature.


• Use less costly materials in the charge, treatment and corrective operations. 


以降低最终铁液的可变性(使工人操作对于正规系 列产生的影响最小)并降低内部废品率。由于可变 性提高了解决废品问题的成本,MeltDeck系统具有 潜在的优势: • 使炉料的使用减到最少 • 通过消除铁液在熔炉中的过热达到节能,在某些 情况下,还可以降低浇注温度


• 在加料、处理和纠正操作中使用成本较低的炉 


Investment Caster Improves Throughput With Cleaning, Cutting Upgrades

精密铸造企业通过升级清理和切割设备提高产能 位于加拿大安大略省布兰普顿市的精密铸造企业


Ontario, Canada, having previously automated its shell department, identified a potential significant bottle- neck in post-cast operations. Because of this, the steel and nonferrous investment casting facility approached Triplex Systems Inc., St Paul, Minn., a supplier of cleaning and cutting systems. To improve DP Cast’s capabilities in its cleaning department, Triplex Systems delivered its High-Pressure Waterjet Casting Cleaning Center and remote-controlled Gator Abrasive Wheel Cut-Off Machine. “We’ve been consistently upping our game to deliver


a better overall customer experience by adding tal- ent, streamlining our process through automation, and seeking ways to improve efficiencies,” said Jan Holland, chairman and CEO, DP Cast. “After doing the research, analysis and site visits, all roads led to Triplex Systems.” Before its investment in upgrading its cleaning


capabilities, DP Cast relied on a manual system that limited throughput. Triplex Systems introduced the manufacturing concept of work cells to water-jet casting cleaning and cut-off operations. Triplex provided the equipment layout for the work cell at DP Cast, includ- ing an overhead gantry crane for ease in moving invest- ment cast trees from cleaning directly to cut-off. “We introduced the combination of automatic and


manual cleaning in a single cleaning solution over 20 years ago,” said Joseph Tebbe, president, Triplex. “Often our Random Automatic Nozzle Movement Automation cleans 90% to 100% of most cast-tree configurations, but with more complex geometries, it’s also beneficial to have a manual cycle.” DP Cast had installed a completely upgraded clean- ing and finishing department that combined cleaning operations. Te turnkey waterjet system allowed DP Cast to improve efficiency and throughput while elimi-


DP Cast公司,先前已对其壳型生产部门完成了自 动化改造,随之发现了铸件后工序存在巨大瓶颈。 因此,这家合金钢和有色金属精密铸造企业与美国 明尼苏达州圣保罗的清理和切割系统供应商Triplex Systems公司取得了联系。为了提高DP Cast公司清 理工部的生产能力,Triplex Systems公司推荐出了 高压喷水式铸件清理中心和远程控制Gator砂轮切 割机。


“我们一直在引进人才、自动化改造、优化工 艺,探寻提高效率的方法,从而提高公司的生产能 力,为所有客户提供更好的客户体验,”DP Cast公 司主席兼首席执行官Jan Holland说:“经过研究、 分析和现场参观后,我们选择了Triplex Systems公 司。”


在升级改造这些清理设备之前,DP Cast公司采 用的是产量有限的手动操作系统。Triplex Systems 公司将工作单元的生产概念引入喷水式铸件清理和 切割操作。Triplex公司为DP Cast公司提供的工作 单元的设备包括悬挂式的龙门起重设备,便于将精 密铸件从清理设备直接吊装到切割设备。 “20年前,我们在单一清理解决方案中引入了 自动和手动清理相结合的方式,”Triplex公司主席 Joseph Tebbe说:“一般情况下,随机自动喷嘴 移动自动化设备可以清理大部分铸件结构的90%到 100%,但是,如果是更加复杂的几何形状,手动循 环操作也是有益的。”
