Foil Extrusion

It is particularly important to feed the media in a uniform volume stream into the die at the production of high-quality flat and blown films. Compared to an extruder, which has to generate a high pressure to fill the die, a gear metering pump performs this function with higher accuracy and with a low-pulsation volume flow. From the energy consumption point of view, it is recommended to have the extruder focused plasticizing. This process design leads to directly increased product quality due to reduced thermal stress of the melt.

Today's ever thinner films present a particularly complex task for the manufacturing process. For decades Mahr gear metering pumps have been established in this process. High efficiency based on pressure stability are achieved by matching the pump to the process.
