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







Hypoeutectic aluminum alloys such as A356.0 (Al-7Si-0.3Mg) are usually subjected to strontium additions in order to obtain a chemically modified eutectic morphology. The modification of the eutectic silicon from sharp acicular plates to a fibrous structure is normally applied to improve the alloy ductility. However, strontium additions are relatively costly […]

Alternative Modification of A356 for Ductility Studied


Automatic or assisted defect recognition (ADR) in X-ray applications has been utilized for decades in the metalcasting industries. Due to advancements of X-ray tubes, detectors and better software with improved algorithms, it is becoming increasingly important in production processes. The first production-approved, inline ADR systems for automotive castings were installed […]

Trends in X-ray Casting Defect Recognition



Southern Cast Products Inc. (SCP) (Meridian, Mississippi) uses an enterprise resource planning (ERP) software system to help with scheduling tasks in its molding and melting departments. This system is in place to help the steel casting facility maximize efficiency when dealing with constraints in both departments. For molding, proper scheduling […]

Cupola furnace operation is a transformation process, meaning numerous inputs are transformed into outputs, primarily iron, slag and the stack gases. This cycle is straightforward and somewhat automatic. Feedback loops made through testing and analysis take more effort, but they ultimately help you improve operations (Fig. 1). The cupola melter […]
