Materion Corp. offers a variety of MoldMax alloys engineered for the high production demands of the plastic mold industry. Both copper-beryllium and beryllium-free MoldMax products are said to provide a combination of strength, thermal conductivity and polishability that shortens cycle time and improves part quality.

MoldMax alloys are designed to resist abrasive wear and galling when used for injection mold components and cavity inserts in direct contact with plastic parts in the injection molding process. They also improve parting line maintenance in the blow molding process and provide longer service life when used for components and inserts in aluminum blow molds, Materion says.

According to the company, the alloys are easy to machine and, in conventional machining operations, will reduce machining time over tool steel. They are available in rounds, square and rectangular bars, plate and forged rings.
