PET sheet extrusion melt pump
The melt pump is mainly used for the transportation, pressurization, and metering of high-temperature and high viscosity polymer melts. Its main function is to pressurize and stabilize the high-temperature melt from the extruder, and maintain a stable flow rate of the melt into the extruder head. Nowadays, melt gear pumps have been widely used in production processes such as chemical fibers, granulation, plastic films, sheets, plates, profiles, pipes, wires and cables, and wire drawing.
PET extrusion melt pump
The melt pump adopts a unique volumetric design, suitable for the transportation, pressurization, and metering of high-temperature and high viscosity polymer melts, making it unaffected by changes in pressure, temperature, and viscosity. The pump provides pressure between the extruder and the mold, and can match the parameters of the extruder to provide a uniform melt with increased output and strict tolerance requirements. It is generally installed between the outlet of the extruder and the head, and is widely used in polymer extrusion molding such as granulation, film, pipe, plate, and sheet materials. It can also be installed in pipelines to transport high viscosity pure materials.
PC sheet melt pump for extrusion
After a series of hot processing and surface treatment such as high-temperature quenching, tempering, quenching and tempering, nitriding, carburizing, carbonitriding, and polishing, the sheet extrusion melt pump has characteristics such as high temperature resistance, high pressure, high wear resistance, and corrosion resistance, which strengthens the requirements for high torque and low shear of the pump body. The pump body has high smoothness characteristics, and the self-lubricating system and inlet and outlet flow channels have been optimized, making it more suitable for PC Extrusion of transparent products such as PMMA and PVC thermosensitive materials. The hardness of the product can reach 62-68HRC, which can greatly meet the requirements of customers for different working conditions.
Plastic sheet extrusion melt pump
The PC sheet extrusion melt pump adopts high-precision gear clearance, which can effectively reduce the pressure of the material barrel, reduce the friction between the screw and the material barrel, reduce the load of the gearbox thrust bearing, and effectively solve the problem of exhaust and overflow of the extruder during the extrusion process. The pump adopts filling sealing and mechanical spiral sealing methods, effectively preventing the occurrence of glue leakage. It has characteristics such as high temperature resistance, high pressure, high wear resistance, and corrosion resistance, which strengthen the requirements for high torque and low shear of the pump body. The pump body has high smoothness characteristics, and the self-lubricating system and inlet and outlet flow channels have been optimized. Linear flow channel design is adopted to effectively reduce the residence time of materials in the pump, enabling the material to achieve excellent plasticization effect and achieve stable and balanced extrusion.
