Accurate measurement with high-speed quality control with PMX It all comes down to the "right amount" of power.
The more effort, asked powder presses, the higher the quality of the produced molded parts. Accurate control requires precise measurement of pressure.
The company Dorst Technologies in the design of a new series of powder presses chose the measuring platform from HBM PMX, specially designed for industrial applications.
Dorst Technologies (Cohelan see) is one of the market leaders in the development of machinery and systems for the production of ceramic and powder metallurgical products. Customers of Dorst Technologies is a leading suppliers of machinery and systems for the production of ceramic and powder metallurgical products, including automotive suppliers, manufacturers of pottery, tools and companies specializing in medical technologies.
The new model EP 70 M is a powerful 70-ton powder press driven by servomotor, pressing ferrous metal powder into a solid product, for example a toothed wheel. "It is very important in this production process to a separate area of the gears, hub, disc, teeth – all have the same density. The better this occurs automatically, the higher quality molded parts," explained Herbert Gröbl, head of development management technologies Dorst Technologies. The density distribution is important because of the details, after pressing, are subjected to specialized heat treatment, and sintering. Uneven density distribution can cause cracks in the molded parts and impair their functional properties.
Accurate measurement, precise control.
The density distribution in turn depends on the power distribution of the stamping machine which acts on the metal powder through the mold. Thus, the forces acting on the individual fields have during the process is continuously monitored for accurate control and immediate correction of any deviations......
