New Maplan "ERGO" Molding Press Promotes Shop Ergonomic Advantages and Productivity

Hanover Park, Illinois. A newly engineered "Ergo" rubber molding press was recently introduced by Maplan GMbh at Europe's K-2004 Rubber Show that will improve manufacturing productivity and contribute to the overall improvement in shop environment, announced David Duginski, president of Maplan/Starlinger North America, Inc.

The "Ergo" was designed to meet user needs for a top-injection rubber molding press who had expressed interest in machine concepts with lower working height without pits or platforms. Maplan engineered their "Ergo" series of rubber molding presses that also solved past attempts to reduce other problems that arose, including: an excessive number of moving parts, inadequate mold support, extremely long nozzles tips, nozzle leakage, and other shortcomings.

The new "Ergo" presses are finding acceptance with manufacturers of elastomer-molded products including the automotive and transportation industry, for farm vehicles, the aviation industry, in the manufacture of pipe couplings, sporting goods, in the making of appliances, and for all markets where rubber-molded components are an integral part of the finished product.

Three models are currently available in the Maplan "Ergo" press series: the MTF 1500/250, MTF 4000/400 and the MTF 4000/650.
Redesigning the clamp unit of the Ergo presses to lower the working height, Maplan engineers were also able to reduce the number of moving parts and maintain the maximum platen support. The combination of a lower working height and the reduction in the number of moving parts serve to increase the speed and reliability of the clamping unit.

The press is equipped with the Maplan FIFO "First-in, First-Out" screw/ram injector that delivers uniformly plasticized and metered-size shot. A constant L/D ratio guarantees the homogenous preparation of the compound. A bonus benefit of the Maplan Fifo injector is the short distance from the pot chamber to the nozzle that reduces the pressure lost during the injection sequence.

Standard equipment for Maplan Ergo presses include: a Maplan PC400 microprocessor control where all process parameters can be set digitally on the control panel, a linear positioning system for the clamping and injection side, five temperature control zones, a separate control panel for manual operation, a cooling unit for plasticizing the cylinder and injection pot, a safety light curtain in the front side of the mold area, and more.

Standard optional equipment available to increase productivity and to meet specific customer specifications include: a Maplan PC4000-plus microprocessor control, hydraulic upper and lower ejectors, heating and cooling devices for the plasticizing cylinder, injection chamber and screw, a vacuum pump, automation devices that include a front and rear center-plate shuttle, an upper and/or lower-side shuttle brushing device, and much more.

Basic specifications and dimensions for the Maplan "Ergo" MTF 4000/400, pictured here, are:
