ABS Extrusion Melt Pump

In the production of ABS luggage sheets and profiles, the combination of ABS extrusion melt pump and single plate screen changer has become the key to achieving high efficiency, stability, and premium quality. These two core devices work synergistically to solve industry pain points such as pressure fluctuations, impurity defects, and downtime losses, providing reliable technical support for high-end ABS luggage manufacturing.

ABS extrusion melt pump

The ABS extrusion melt pump serves as the pressure stabilization and metering core of the extrusion line. Designed for ABS’s high viscosity and processing temperature (240-280℃), it features precision-machined gears that minimize pressure fluctuations to within ±1% . This eliminates thickness unevenness and surface defects like "shark skin" on luggage sheets, ensuring consistent dimensional accuracy (±0.05mm tolerance) . By taking over pressure-building tasks, it reduces extruder backpressure by 30%-50%, cutting energy consumption by 15%-25% and boosting production capacity by 20%-35% . Its optimized flow channel design prevents ABS thermal degradation, maintaining product toughness.

Polymer melt pump

Paired with the single plate hydraulic screen changer, the system achieves continuous purification of ABS melt. Equipped with 50-150 mesh filters, it effectively removes carbides, metal particles, and undissolved impurities from raw materials (including recycled materials) . The hydraulic-driven switching takes only 1-2 seconds, enabling non-stop production and avoiding waste from traditional shutdowns . Its compact structure fits seamlessly into luggage extrusion lines, with reliable sealing to prevent melt leakage even under 30MPa pressure .

Together, these devices elevate ABS luggage quality by ensuring uniform thickness, defect-free surfaces, and stable mechanical properties. For manufacturers, they reduce scrap rates from 8%-15% to below 2%, extend equipment lifespan by 30%, and lower operational costs . As essential components for high-precision ABS extrusion, they empower businesses to compete in the premium luggage market.
