Supplier Stories for the Week of March 17

Zirconium-based Amloy alloys and copper-based materials from Heraeus could be injection molded into components in a fully automatic production process using Engel’s newly developed AMM injection molding machine from its hydraulic victory series. Very small wall thicknesses are possible, Heraeus reported in a news release. Cycle time can be up to 70 percent shorter than with previous amorphous metal injection molding solutions, and the required heating power can be reduced by 40 to 60 percent.  Thanks to a surface fineness of 0.05 µm Ra, manual reworking or further surface finishing are not necessary for most applications. Injection molding of amorphous metals is described as superior to MIM (Metal Injection Molding) and CNC machining. MIM processing of metal-plastic powders requires further work steps such as debinding and sintering. CNC machining requires considerably more time and generates a large amount of waste, it was reported.At the Hannover Messe 2019 April 1-5 at Booth E32 in Hall 3, Heraeus and Engel will demonstrate the Amloy brand’s potential for delivering components that combine high mechanical durability with high reliability, low wear, scratch resistance, and reproducibility.Amorphous metals are named such because of their randomly arranged – amorphous – molecular structure. Amloy components are hard yet highly elastic and have a low wall thickness while remaining durable, light, and robust, it was reported. Amloy is biocompatible in line with ISO 10993-5. Applications could include durable instruments for minimally invasive surgery. [Image courtesy of HERAEUS]Editor's Note: If you have news you’d like to submit for potential inclusion in future weekly roundups, please send a press release and any related images to with the subject line “Supplier Stories.”
