Demag demonstrates its surgical precision through the IntElect
Demag Hamilton Ltd. will demonstrate its IntElect machine at Interplas trade fair held in Birmingham. The machine is designed to the production of precision components for medical, diagnostic and pharmaceutical applications under cleanroom conditions.
An IntElect 50-45 with a clamping force of 500 kN, the smallest model of the IntElect series will be shown in Septemeber at Interplas 2011. The machine will be seen during production of control knobs with a diameter of 3.5 mm made of polyacetal (POM) for hearing aid devices in a cycle time of 10 seconds. Precise and sensitive drives and automation integrated in the machine make possible to manuafacture medical micro compnents with absolute reproducibility and zero-defect production, in the case of control knobs, mouldings weighing a mere 10 milligrams and having a shot weight of only 280 milligrams.
The production cell has been designed and developed by Sumitomo (SHI) Demag and its partners. Stamm AG of Hallau from Switzerland designed and built the four-cavity cold runner mould with a tunnel gate that is responsible for the production of particularly challenging micro mouldings from a wide variety of different plastic materials and uses a number of machines supplied by Sumitomo (SHI) Demag.

Another partner, Max Petek Reinraumtechnik of Radolfzell from Germany made the cell, built according to cleanroom standards, and the laminar flow with the filter fan unit purifies the air brought in from the outside, and provides a constant laminar air flow above the mould mounting space of the machine, which prevents particles from entering to guarantee ISO 7 production environment of a cleanroom class. Integration of the six-axis robot from Yaskawa Europe GmbH into the injection moulding machine is made by German specialist in automation solutions, MAi GmbH & Co. KG of Küps. Design and configuration of the robot ensure a complete, fully automatic visual inspection within the cleanroom production cell and make the susceptible mouldings less likely to become contaminated during unloading, inspection and packaging.
Work of high-quality specialists resulted in a flexible and economical machine with NC5 efficeint controling system and large tie bar clearances, linear guidance for maximum platen parallelism, outstanding reproducibility and process capabilities as well as high levels of reliability and availability.
The IntElect 50-45, presented during Interplas is fitted with a 14 mm screw for plasticization of small volumes of material with low shot weights. The patented activeLock non-return valve is designed to prevent any material back flow over the screw tip, that ensures a precise and consistent shot volume over a large number of cycles. Resulted products are of high quality, this mainly applies to precision mouldings with very low shot weights, such as the hearing aid device component. Combining the comprehensive monitoring of closing force during mould movement and the fast NC5 machine control system, the highly sensitive activeQ mould protection system is designed to effectively protect the, often expensive, mould against wear or damage.
The IntElect smart is produced by Sumitomo (SHI) Demag produces at its centre of excellence for electric machine technology in Wiehe in Thuringia, Germany. The IntElect smart is available in eight clamping forces of between 500 and 4,500 kN. Sumitomo (SHI) Demag will also present the IntElect and other machines during a special press breakfast held on on Wednesday, 19 October 2011 at 08.00 a.m. at Fakuma 2011.
