Ashland develops method to increase productivity for metal casting industry


A new test method designed to evaluate the sticking and release characteristics of mold and core binders was presented at CastExpo on May 18, in Atlanta, Ga., by representatives from Ashland Casting Solutions, a business group of Ashland Performance Materials, a division of Ashland Inc. (NYSE: ASH).

The presentation introduced a method developed by Ashland scientists that has the capability to produce a core and measure the ejection force immediately after it is cured. This process provides more accuracy compared to previous tests that have a built-in time delay. The new method also creates an improved means for evaluating release agent performance.

“Ashland continues to develop new core test methods that are more accurate and representative of the processes that our customers actually use. The new test will help us develop new release agents and to select the best products to meet specific applications for our customers,” said Steve Smith, project manager for Ashland Casting Solutions.

The new test method is shown to improve accuracy and repeatability and will provide the industry with a variable tool to evaluate existing systems.

The paper entitled “Evaluating Core Sticking and Release,” was presented by Smith and was co-authored by Ralph Showman, senior staff scientist for Ashland Performance Materials, Desheng Sun, staff development chemist for Ashland Casting Solutions, and Karl Schumacher, senior laboratory technician for Ashland Casting Solutions.
