Metalcasting facilities are constantly seeking new ways and opportunities to improve their casting quality, productivity and savings—all at the same time. In response, DISA has developed a system that enables foundries to boost both quality and productivity, while improving yield, compared to other standard vertical molding processes. One of the […]
Pouring
Lanthanum containing MgFeSi has been used in ductile iron production for 40 years. First solely for “in the mold” processes and then in the last 12 years it has seen increased use as a ladle alloy. These alloys have gained popularity for several reasons, such as shrinkage reduction, improved microstructure […]
Optimal Design of Pure Lanthanum Based MgFeSi Alloy for ...
Grede Foundries Inc. was involved in the partnership that originally built ductile iron casting facility Novocast, Nuevo Leon, Mexico, in 2001, but exited the partnership in 2007. In early 2011, Grede Holdings, formed after consolidation with two other U.S.-based metalcasters, reacquired the metalcasting facility. In the ensuing three years, Novocast […]
Novocast’s Optimistic Outlook
Due to its generous hydraulic basins, more than 90% of electricity in Quebec, Canada, is produced by water turbines. However, numerous sites cannot be economically, technically or environmentally developed using conventional hydropower technologies (i.e., hydroelectric dams). Novel low power water turbines are sought to suit shallow, high flow rivers; they […]
Direct Pour Vs. Traditional Gating
3 Developing a successful, repeatable, reliable process for pouring aluminum into a permanent mold is no simple task. The many variables include metal and mold temperatures, shrink factors, mold coatings, casting cycle times and melt quality. Considering the numerous factors that influence quality and quantity, introducing sand cores to permanent molds […]
Keys to Success in Semi-Permanent Mold Casting
To reduce the cost of preparing a semi-solid slurry, grain shape must be refined and improved by controlling the pouring temperature or using a low pouring temperature. Liu Zheng, Material and Chemical Engineering Institute of Jiangxi University of Science and Technology, Ganzhou, China; Mao Weiming, Materials Science and Engineering Institute […]
Semi-Solid Aluminum Alloy Slurry for Rheocasting
Examine your metallurgy, tooling and molding practices to improve the quality of your castings. Doug White, Elkem Metals Inc., Boca Raton, Fla. Several factors in ductile iron melting and pouring can be controlled to maximize yield and reduce shrinkage. Whether dealing with a problem part or a need to improve […]
