For cast pump components, and especially for the core and impeller, 3-D printing of the sand casting molds now eliminates the need for an entire post-processing step. The industry puts the post-processing time per impeller at an average of 10 to 15 minutes and this is exactly where clever companies […]

25 Years of Tribo-Chemie
Metal casters continually strive to produce the highest quality castings at the lowest competitive cost. Unfortunately, they have little control of the cost of the required materials. Molding materials such as chromite, zircon and mullite all exhibit low expansion, leading to few casting defects related to expansion and better dimensional […]
Using Specialty Sand Blends to Reduce Veining Defects
Less than five years ago, the mining of olivine sand ceased in the U.S., leaving North American metalcasters looking for alternative sources. Some chose to import olivine sand from Norway, though the increased shipping costs when compared to a domestic supplier made this an expensive option. For voestalpine Nortak’s metalcasting […]

Less emissions with solventless Cold Box binders
Introduction In recent years there has been a drive to increase the re-use of foundry sands to limit the cost of new sand purchases and to minimise both the cost of dumping used sand and to limit environmental impact. Traditional foundry sands systems are often based on silica sand, with […]
Characteristics of synthetic sand and application of refractory coatings
There is a sand reclamation plant to suit every metalcasting facility requirement and budget. Chris Wilding, Omega Foundry Machinery Ltd., Peterborough, U.K. Today’s chemically-bonded sand metalcasting facilities are under increasing pressure to reduce costs and their impact on the environment while improving and maintaining casting quality. One of the ways […]
Sand Reclamation for Chemically Bonded Sand Systems
The idea of reducing seacoal use to control metalcasting facility emissions has gone from the theoretical to the practical. Vic LaFay, S&B Industrial Minerals, Cincinnati, and Jim Schifo, Keramida Inc., Indianapolis Pride Cast Metals, Cincinnati, has overhauled its sand system in the past four years in the face of mounting […]
