Sand Solutions

Castalloy Foundry reduced costs and lowered its environmental footprint with the Simpson Pro-Claim®—achieving $574K in first-year savings, reduced energy use, and full ROI in under a year.

Progressive Foundry improves sand consistency with the Simpson Multi-Cooler®, achieving ±2 compactability 90% of the time, ±3 up to 98% of the time, and reducing bond usage by 7%—driving more stable processes, improved efficiency, and reliable casting performance.

Batch size plays a critical role in green sand mulling. This article explains how inaccurate or inconsistent batch weight affects clay activation, water additions, and overall sand performance—often leading to variability, defects, and downtime. Learn why batch size matters, how hidden measurement errors can impact your process, and simple checks foundries can perform to maintain consistent sand conditioning and reliable molding results.

By implementing Monitizer® | DISCOVER on its Simpson Speedmullors® and integrating Simpson Hartley® controller data, Aalberts IPS Americas reduced sand-related downtime by 83% while gaining real-time visibility into its sand system.

Customer success story highlighting how addressing inconsistent mold hardness and strength helped a green sand foundry reduce casting defects and improve surface finish through proper mold testing.

Inconsistent mold hardness and mold strength can cause casting defects and poor casting surface finish. Testing the mold should be standard for green sand foundries.

Ensure quality castings with in-house sand testing—prevent defects, reduce scrap, and optimize production.

By understanding the charged nature of clay, the importance of mulling, plus clay’s interaction with water, it’s possible to optimize sand preparation for consistent and defect-free molds.

Waupaca Foundry boosts sustainability with the Simpson Pro-Claim, reducing waste and reusing sand over 30 times. Discover their efficient, cost-saving process.

Hot sand presents a major challenge in green sand molding, affecting casting quality and production. Understanding its causes, effects, and control methods is key to reducing defects and boosting productivity in foundries.

Discover how Grede partnered with Simpson and the Monitizer platform to enhance sand control, reduce scrap, and optimize foundry operations.

Explore how the Simpson Pro-Claim is transforming the landscape of sand reclamation while helping foundries save money and enhance their overall operations.

Our Simpson Pro-Claim sand reclamation equipment is a game-changer for the foundry industry. It allows you to clean, regenerate, and recycle waste sand for reuse.

Compactability is one of the most essential and common tests in foundry green sand. The ability to properly measure and control compactability, allows the foundry to reduce variation in other parameters, including green strength, moisture, friability, flowability, cone jolt, density, permeability, and wet tensile.

Precise water control, effective mulling, sand cooling, and early water introduction can optimize clay activation and reduce free water for optimal mold and core production.

“Muller-type mixers are quite unusual in Europe but we saw it as a superior mixer technology,” states Franz.

A complete connected foundry supports big ambitions at Pennsylvania-based Donsco.

In this article, we will look at trending daily sand data, and how to use results to determine variability in the sand system.

Testing for permeability is critical for a foundry operation because the level of permeability can explain the causes of certain defects that can occur to metal castings.

The Simpson Analytics PFP Mold Strength Tester is used to determine the strength properties of clay-bonded foundry sand.

The only way to properly determine the performance and expected payback of reclamation is to conduct a test at the Simpson Performance Laboratory.
