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

CGL制造公司(CGL)是一家自豪的供应商，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机械铸造、制造和组件。在样品加工过程中，CGL为客户提供铸造金属零件，但铸件的准备工作非常耗时。添加制造(AM)，也被称为3D打印，是一个减少样品周转和生产时间的机会。CGL向客户提供铸铁件(球墨铸铁)，但这不是用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的测试和迭代，才能生产出机械特性与铸铁零件相似的样品产品。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来开发金属粉末、AM参数和后期生产工艺，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已经在NSERC和安大略省英才中心资助的项目上进行了合作，对AM复制铸铁的潜力进行了早期调查。该项目将有助于开发AM用球墨铸铁粉的市场，并彻底改变CGL的样品零件生产过程。项目成果将有助于降低添加剂制造的风险，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，从而节省CGL在样品生产中的大量时间。学生将在学院和大学层面接受培训，并在一个独特的多机构和多学科项目中获得宝贵的研究和行业经验，该项目是为安大略省一家重要的CGL制造商提供的，CGL位于安大略省圭尔夫。

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.
