MX Series High-Throughput Mounting Presses
Smart, Modern Metallographic Mounting
The LECO MX Series of metallographic mounting presses, including the MX400 and MX500, are fully automatic; benchtop systems designed to streamline and accelerate your sample mounting process. These presses deliver fast cycle times, dual-sample mounting, and an intuitive touchscreen interface in a slim, space-saving design. Built for high-throughput labs, they improve workflow efficiency through automation, making it easy to produce clean, consistent mounts with minimal effort.
Why Choose the LECO MX Series
Optimized for Speed and Productivity
Each MX-Series press offers fully automated mounting—just load the sample, press Start, and the system handles heating, pressure, cooling, and release. Fast cycle times (as quick as 6–7 minutes for a 1.5″ mount) and dual-mounting capability double throughput, making the MX Series ideal for high-volume labs needing consistent, hands-free operation and efficient specimen preparation.
Effortless, Jam-Free Operation
The MX Series features an innovative swing-style crossbar that opens effortlessly with one hand, eliminating the strain and safety risks of older press designs. Its jam-free, low-maintenance closure ensures fast, ergonomic operation, while built-in safety interlocks prevent use unless securely closed—making it ideal for high-throughput, user-friendly mounting.
Compact Design & Versatility
With a slim 8″ footprint and vertical design, MX-Series presses fit easily on crowded benches and can be lined up to boost throughput. The 7″ touchscreen offers intuitive swipe-and-tap controls, preloaded and customizable methods, and real-time cycle progress. Multilingual support and unit flexibility ensure easy, confident use by any operator.
Scalable Solutions for Every Laboratory
The MX400 and MX500 both offer fast, automatic cycles, dual-mount capability, jam-free operation, and an intuitive touchscreen interface. The MX400 is ideal for labs using a single mold size, available in fixed diameters from 1.25″ to 50 mm. The MX500 adds flexibility with quick-change mold cylinders for all five standard sizes, making it perfect for labs handling varied or evolving sample needs. Both models maintain rapid cycle times and support accessories like water recirculation and exhaust hoods for enhanced efficiency and daily use.
Efficient Cooling & Water Conservation
The optional MX Water Recirculator is a compact, closed-loop cooling system that conserves water and simplifies setup by eliminating the need for plumbing. Its efficient air-cooled design accelerates cooling, enabling faster, consistent cycle times—even during continuous, high-throughput use.
