Our engineering team is always prepared to respond to client requests for solutions. The sand preparation equipment maker Simpson of Naperville, Illinois, was looking for a liner that would protect their machinery and make molding sand more consistent. Improved mulling efficiency, reduced maintenance costs, longer service life, and wear indication are just a few of the important benefits that our team’s specially designed liners provide. Kastalon’s engineering genius is on full display with our urethane-lined mixing bowls, and we couldn’t be happier to brag about our incredible team!

In industrial foundry applications, a urethane-lined Simpson mixing bowl is primarily purchased for its extreme durability and efficiency in high-production environments. These liners are designed for Simpson intensive mixers, such as the Speedmullor and Multi-Mull, to protect the equipment and improve the consistency of molding sand.
Core Benefits for Foundry Operations
- Extended Service Life: Polyurethane liners are a long-term solution that typically outlasts standard rubber liners by three times or more.
- Reduced Maintenance Costs: Because they are highly resistant to wear, these liners minimize the frequency of replacements and the associated labor costs during maintenance shutdowns.
- Maximized Mulling Efficiency: The liners are specifically formulated and precision-fitted to help the mixer achieve optimal sand quality and uniformity.
- Wear Indication: Many Simpson urethane liners feature a bright yellow color that acts as a visual wear gauge; as the color fades over time, it indicates exactly when the liner needs to be serviced or replaced.
Design Advantages
- Secure Mounting: Simpson’s design uses larger diameter washers and reinforced mounting points to prevent bolts from pulling through the urethane, ensuring the liner stays firmly attached to the bowl and door.
- Close Tolerance Fit: The liners are manufactured for a precise fit within the mixer bowl, which prevents sand buildup and ensures consistent performance across the entire mixing cycle.
- High Performance: For high-volume foundries, the initial investment in urethane is often offset by the reduction in “profit-robbing downtime” caused by frequent parts failures.
