Hilma-Roemheld GmbH (Hilchenbach, Germany), a global provider of systems for the industrial manufacturing, assembly, clamping and drive industries, has introduced magnetic clamping technology for molds and dies that complies with the EN 289 standard for plastic and rubber molding machines. It is the main focus at this year's DKT/IRC International Rubber Conference in Nuremberg, Germany, from June 29 to July 2.
Roemheld points out in its release that the Hilma magnetic clamping plates in the M-TECS series are currently the only ones that meet the new version of the European standard, which went into effect in January 2014. They comply with safety requirements related to mold monitoring, power supply, magnetization and emergency stopping at performance levels D and E.
The new controller is available for all magnetic clamping plates in the M_TECS series. They belong to the quick clamping system, which allows dies and molds of any size, geometry and weight to be rapidly positioned and clamped. Roemheld offers a variety of quick clamping systems that are designed for use at varying operating temperatures up to 240°C. All magnetic clamping plates are available with an optional integrated heating unit and are delivered in custom sizes and geometries.
Roemheld notes that the magnetic clamping systems can be easily retrofitted to existing vertical or horizontal injection molding machines, mold carriers and transfer molding. The combined use of long and square poles takes full advantage of both technologies—the high force concentration of the long poles and the inexpensive design of the square poles.
Setup times are reduced to just a few minutes, making it convenient for job shops and companies that do a lot of small-series manufacturing. Using magnetic force to clamp the mold reduces the risk of an accident because the machine operator does not come into direct contact with the hot working surfaces.
