Pre-Hardened Mold Steel Material Increases Through-Hardened Ability
Finkl Steel’s patented pre-hardened mold steel grade MD Xtra material achieves high impact strength, enhanced thermal conductivity and is an exceptional solution for deep impression applications.

According to Finkl Steel, MD Xtra has proven through-hardenability on molds up to 45 inches in thickness, with hardness loss from surface to the core of roughly 3 HRC points. The material has been specifically engineered to support laser hardening, chrome plating, nitriding, texturing and has excellent weldability. One of the added benefits, says the company, is that customers will not need to change the weld material from what is being used on standard MD material. According to the company, MD Extra iscurrently used in molds that require high wear-ability, including glass-filled parts.
MD Xtra is also offered in the "Super-Hard" condition at 38-43 HRC for high-polish requirements and a vacuum arc re-melt version MLQ Xtra for a high-gloss finish (SPI A1 or greater).
While EDM speeds today are impressive, there are a number of machining variables that influence the machining speed of the wire EDM.
Moldmakers are under constant pressure to cut costs and production time. Determining whether high-speed milling or EDM'ing - or perhaps a combination of both - is the best option may be what makes or breaks a job.
When evaluating new processes for mold manufacture, jig grinding is worth a second look as machine manufacturers have now added high accuracy features to guarantee repeatable results.
