Application of HAIKE Melt Pump in WPC Production Line

Wood-plastic profile production line is mainly used for PVC + wood flour, the production of kicking angle, door line, door line, louver, photo frame, frame, door frame, door cover, window cover, Extrusion and other profiles. The production line adopts the original WPC process and formula, according to the different profile sections, different purposes, design a different proportion of products, use different specifications of WPC special twin screw extruder, with Hypertherm special melt pump. Traction machine Unique technology, stable work, good reliability, great traction. Vacuum stereotypes with a special eddy current Cooling System for easy cooling stereotypes to meet the production needs of wood-plastic profiles. Cutting device and profile traction speed synchronization, design, stable operation, automatic cutting, and equipped with dust recovery device.

HAIKE WPC WPC Melt Pump is mainly used for conveying, pressurizing and metering high temperature and high viscosity polymer melt. Its main function is to pressurize and stabilize the hot melt from the extruder, keeping the melt flow accurately and steadily into the extruder head. Today, the melt gear pump has been widely used in chemical fiber, granulation, plastic film, sheet, sheet, profiles, pipe, wire and cable, drawing, composite extrusion and other production lines, Machinable materials cover most of the polymer Materials such as PE, PC, PP, PVC, HIPS, PS, PA, TPUR, fluoropolymers, polysulfones, polyesters, thermoplastic elastomers, rubber and thermal adhesives. Ocean Branch melt pump is a positive displacement conveyor equipment, high-precision gear gap and volume structure design, so that a stable and balanced extrusion possible, chemical fiber, granulation, plastic film, sheet, sheet, , Wire and cable, drawing, composite extrusion and other production lines have been widely used, and achieved good results:

1. To achieve a stable extrusion, extrusion products to improve dimensional accuracy, reduce scrap rate. In the extrusion process, the uneven feeding of materials, barrel and head temperature fluctuations, pulsating speed and other phenomena is difficult to avoid. The use of melt gear pump can eliminate feeding system feeding error, can greatly reduce the upstream process of transmission fluctuations, rapid access to stable working conditions, improve the dimensional accuracy of extruded products, reduce scrap rate.

2. To increase production, reduce energy consumption, low temperature extrusion, extend the life of the machine. Since the extruder is equipped with a polymer melt pump, the decompression function of the extruder is transferred to the gear pump, and the extruder can work under the condition of low pressure and low temperature, the leakage flow is greatly reduced, and the output is increased. Gear pumps create head pressure more effectively than extruders and reduce backpressure on the extruder, allowing the screw to withstand the axial forces and prolonging service life.

3. With linear extrusion characteristics, to facilitate the coordination of downstream equipment. As the gear pump leakage less, the pump capacity and speed of the basic linear relationship between the gear pump speed changes, the flow can know exactly, because it can determine the upstream and downstream equipment and gear pump synchronization work speed, the use of gear pump Entrance and exit of the collection of pressure, temperature and other information to achieve the entire extrusion process online monitoring and feedback control.
