Melt gear pump in plastic extrusion processing of universal application

Supercharging screw melt gear pump makes the working pressure drop , resulting in reducing the shear stress melting temperature. In 7.69MPa pressure may drop about 6 ℃, which for a high viscosity , heat-sensitive molding materials is very important . In the production of LLDPE blown energy efficiency is improved. In actual production , LLDPE blown film the energy efficiency achieved in the 3 ~ 6kg / (kw.h) range , and for a Melt pump for extruder mounted on the extruder , the energy efficiency is up to 16kg ( kw.h).

Has broad applicability to External melt pump combination obtained so that the device can be benign with a wide field of application , in fact, such a device can be a variety of different plastics processing, and produce a variety of products , especially when machining difficult materials and manufacturing precision products, it can bring out their strengths, such as due to the role of regulator melt extrusion gear pump reduces volatility , so this combination is particularly suitable for the production of high-precision equipment thin thin products, such as PET, PS, PP and PA contour oriented film , because the volatility of these materials are particularly sensitive to pressure and flow for multilayer coextruded films. This product each film are very thin , in order to reduce product cost, recycled material sandwiched between layers . So it 's more difficult process , and the creation of co-extruded melt gear pump head was to provide a stable flow rate to ensure the accuracy of component layers , particularly the city to ensure the existence of adequate impermeable interlayer between agents or adhesive.
