As the core equipment in the extrusion production of polymer materials, melt pump is mainly characterized by the following performance:
I. High-precision control capability
Accurate measurement of flow
The quantitative delivery of melt is realized through the precision gear meshing structure, and the rotational speed can be adjusted accurately to control the flow rate, which ensures that the thickness of the extruded products (e.g., sheet, pipe) is uniform and consistent, and significantly reduces the scrap rate.
Stabilized pressure output
effectively suppresses pressure pulsation of the extruder, provides continuous and stable melt pressure, reduces dimensional tolerance caused by pressure fluctuation, and improves product consistency.
II, excellent stability and adaptability
High-temperature and high-pressure resistance
Adopting high-temperature tool steel and other special materials, it can withstand high-temperature environments of hundreds of degrees, and maintains stable operation in high-pressure extrusion of high-viscosity melts, such as plastics and rubber.
Wide material adaptability
Optimized design of sealing system and runner structure can handle all kinds of polymers from low viscosity to high viscosity (such as PP, PVC, silicone) to adapt to different production needs.
III. Energy efficiency and reliability
Reducing energy consumption and equipment load
Reducing extruder load through stable melt transport reduces energy consumption per unit of production; meanwhile, the optimized gear design reduces shear heat, further saving energy.
Extend equipment life
Wear-resistant gears and reinforced seal design, combined with corrosion-resistant materials (e.g., high-temperature tool steel), ensure long-term stable operation in continuous production and reduce maintenance costs.
Advantages of Structural Design
Compactness and Ease of Maintenance
Modular design has a small footprint and supports horizontal, vertical and other multi-directional installation; the dead-end-free design of the flow channel reduces material residue and facilitates cleaning and maintenance.
Enhanced sealing and lubrication
The special lubrication runner design is suitable for elastomer materials, combined with multi-layer sealing technology, completely preventing the leakage of high-temperature melts and guaranteeing production safety.
