Better mulling and less downtime
- Increased durability
- Higher wear resistance
- Plows last longer therefore fewer change outs required
The Challenge
In order to meet the demands of our customers who wanted plows with a longer life-span we now offer carbide/ceramic plows for the Simpson Speedmullor. Compared to the standard plow, the carbide/ceramic plow is much more durable and has a higher wear resistance. The new carbide/ceramic plows will improve performance and minimize downtime for maintenance.
Simpson Solution
Simpson tested the surface coating durability of three plow types: a ceramic-faced plow, a special alloy-coated plow, and a standard carbide plow. Each operated 24/5 for eight months. Results showed that carbide/ceramic plows delivered significantly higher wear resistance and longer service life in sand applications.
Why Ceramic/Carbide Outperforms Standard Carbide:
- Ceramic/Carbide plows feature high-abrasion surfaces that let sand slide smoothly for improved mulling and reduced wear.
- Standard carbide plows have carbide only on the bottom radius and back side, causing faster face wear and a ripple effect.
For better mulling performance and reduced downtime, foundries worldwide choose Simpson Carbide/Ceramic Plows for the Speedmullor.
