THE MOOG EAS SYSTEM INCREASES ACCURACY, EFFICIENCY, AND PRODUCTIVITY FOR FREY AND CO. - 1

THE MOOG EAS SYSTEM INCREASES ACCURACY, EFFICIENCY, AND PRODUCTIVITY FOR FREY AND CO. Summary Frey and Co. was looking for modern, more efficient technology to replace the previous hydraulic system solution used in their EasyISO 2000 – 4000 KN ceramic isostatic presses. In cooperation with Frey, Moog developed a new, modern EAS (electrohydrostatic actuation system) consisting of a function block with an integrated EPU (electrohydrostatic pump unit). The EPU is conceived of as an energy saving solution that can be designed very flexibly according to the chosen infrastructure. Frey and Co. Background Frey and Co. was founded in 1989 by Dieter Frey, and the company’s facilities are located in Lenggries Fleck, Southern Bavaria, Germany. As a leading manufacturer of adaptor tools, press machines and automation systems for the powder metallurgy sector, the company provides innovative applications for the medical, electronics, automotive and ceramics industries. Frey have many years’ experience in tool and adaptor construction and the development of specialized machines. Principally, the company’s employees deal with the design, manufacturing and assembly processes, and the company have a worldwide sales network in South Korea, China, South America, the Czech Republic, Russia and several other countries. Frey’s EasyISO ceramic isostatic presses are used in the production of ceramic parts with an even density distribution and long lengths. Cold isostatic pressing (CIP) is a materials processing technology whereby high pressure is applied to ceramic powder in a sealed elastomer container, shaped specifically for the application. During the manufacturing process, the powder is converted from loose aggregate into a partly dense compact with enough strength to permit handling, before it is transferred to the next stage of the process. The EasyISO Series is equipped with a pressure vessel, a pressure intensifier and a locking cylinder built into the press frame. The machines have a modular structure for press forces ranging from 2,000 to 10,000 KN and can be tailored to specific customer requirements. In short, each press can be defined between different press pressures as well as component sizes within a specific framework. WHAT MOVES YOUR WORLD Frey and Co. facilities, Lenggries Fleck, Southern Bavaria, Germany (photo courtesy of Frey and Co.) The company’s presses perform production functions that range from manual removal and filling to fully automated manufacturing lines. Depending on the type of aggregate powder used, presses are fitted with dies that are replaced after each cycle. Frey’s EasyISO presses are very cost effective and are required to produce long ceramic parts with an even density distribution. The Challenge The collaboration between Frey and Moog began in 2010 with the development of a new hydraulic powder press. In 2018 the partnership continued to develop further, this time with the aim of jointly developing an improved, futureoriented drive system for the EasyISO press machine series. The original design of the EasyISO 2,000 and 4,000 KN presses included a traditional hydraulic system solution for five individual machine axes that Frey had used for many years, and which was supplied by a leading Moog competitor. This complex motion control solution was not ideal as required considerable maintenance and had high energy consumption, which increased operating costs to challenge overall company productivity. Aiming to introduce new, smarter and less complex motion control technology to their press machinery, Frey approached Moog with the goal of introducing more up to date, efficient drive technology for their isostatic pr

THE MOOG EAS SYSTEM INCREASES ACCURACY, EFFICIENCY, AND PRODUCTIVITY FOR FREY AND CO. - 2

The Outcome The Moog EAS improved the repeatability and accuracy of the EasyISO press series, and it also proved easy to use. Overall, the system reduced noise levels on the basis that the EPU delivers power only when it is needed, which also greatly improved energy efficiency by more than 40 % and also helped reduce operational costs. In terms of the requirements of the isostatic press market, by replacing the hydraulic system on Frey’s press series with the Moog EAS resulted in increased productivity, higher quality ceramic parts as well as a more stable production process. The EPU’s...
