Development of a New Powder Mix and Process Plan to 3D Print Ductile Iron Parts

CGL制造公司(CGL)是一家值得骄傲的机加工铸件、装配和组件供应商，为铁路、材料处理、建筑、林业、采矿、重型卡车、农业和国防工业的顶级品牌提供服务。对于其样品工艺，CGL为客户提供铸造金属零件，然而，铸造准备是耗时的。增材制造（AM）也称为3D打印，是减少样品周转和生产时间的机会。CGL向客户提供的零件为铸铁（球墨铸铁），然而，这不是AM常规生产的金属。因此，需要对金属粉末、AM工艺和后处理进行大量测试和迭代，以生产出具有与铸铁零件相似机械特性的样品产品。莫霍克学院和圭尔夫大学拥有专业知识、AM机械、材料测试和金属专业知识，可以开发金属粉末、AM参数和后生产工艺，以创建适合CGL及其客户需求的样品零件。圭尔夫大学和莫霍克学院合作开展了一项由NSERC和安大略实验中心资助的项目，对AM复制铸铁的潜力进行早期调查。该项目将有助于开发AM用球墨铸铁粉末的市场，并彻底改变CGL的样品零件生产工艺。该项目的结果将有助于降低增材制造的风险，并支持CGL的创新议程目标。该项目将先进的制造策略与参数调整、数据分析和迭代相结合，以创建一个有价值的业务解决方案，从而为CGL节省大量的样品生产时间。学生将接受培训，并给予宝贵的研究和行业经验，在一个独特的多机构和多学科的项目，在圭尔夫，安大略的一个重要的Ontario制造商。

CGL Manufacturing Inc. (CGL) is a proud supplier of machined castings, fabrications, and assemblies for top brands in the rail, material handling, construction, forestry, mining, heavy truck, agriculture, and defenseindustries. For its sample process, CGL provides its customers with cast metal parts, however, the castpreparation is time consuming. Additive Manufacturing (AM) also known as 3D printing is an opportunity to reduce the sample turnaround and production time. CGL provides parts to customers as cast (ductile) iron,however, this is not a metal conventionally produced with AM. Therefore, significant testing and iterations are required for the metal powder, AM process, and post-processing to produce a sample product with similarmechanical characteristics to a cast iron part.Mohawk College and the University of Guelph have the expertise, AM machinery, materials testing, andmetals expertise to develop metal powder, AM parameters and post production process to create sample parts that suit CGL and their client's needs. The University of Guelph and Mohawk College have collaborated on a prior NSERC- and Ontario Centres of Excellence-funded project to perform early investigations of thepotential for AM to replicate cast iron.The project will help to develop the market for ductile iron powder for AM, and to completely transform CGL'ssample part production process. The project results will help to de-risk additive manufacturing and supportCGL's innovation agenda goals. This project is combining advanced manufacturing strategies with parameter adjustments, data analyses and iterations to create a valuable business solution that will save CGL significant time in its sample production. Students will be trained and given valuable research and industry experiences at a College and University level in a unique multi institution and multidisciplinary project for an importantOntario manufacturer with CGL in Guelph, Ontario.
