Our company is a high technology enterprise which produces melt pumps (melt metering pump, melt gear pump, ZB-B). We are in the State Department of Overseas Scholar Pioneer Park of Zhengzhou High&New Technology Industries Developments which has convenient transportation and excellent surroundings. We have accumulated abundance experiences on the application technique of melt pump since we introduced advanced technology from foreign nations. Recently, according to the development trend of world melt pump application technology, we make extensive research on the pumps' operational performance, practical function, equipment structure, control technology and have achieved regular achievement. Melt pump is mainly used in high temperature and high viscosity polymer melt transport, turbo, measurement. Foreign countries widely apply in plastic, resin, rubber extrusion, such as granulation, film, pipes, plate, etc. With the increasing development of mechanical industry, melt pump is increasingly accepted and applied by domestic.
