Polymer Melt Gear Pumps: Essential for These Applications!

As the “precision steward” for high-viscosity melt transfer, polymer melt gear pumps deliver stable pressure control and uniform flow output, making them widely adaptable across polymer material processing scenarios. Their core applications primarily include:

1. Plastic Extrusion Molding Industry (Core Application)

Covering nearly all plastic extrusion scenarios from daily goods to industrial components:

Pipe/Profile Extrusion: Ensures uniform wall thickness and dimensional accuracy for PVC drainage pipes, PPR water supply pipes, aluminum-plastic composite pipes, window/door profiles, and specialty extrusions through stable melt delivery.

Film/Sheet Extrusion: Including PE cling film, PET packaging film, PP decorative sheets, etc. Precise melt flow control ensures uniform film thickness and smooth, wrinkle-free surfaces.

Cable Sheathing Extrusion: PVC/PE insulation and sheathing layers for wires and cables. Ensures consistent coating thickness, enhancing insulation performance and service life.

Special Product Extrusion: Processes PC lampshades, acrylic sheets, plastic welding rods, etc., accommodating high-viscosity melts while improving material plasticization uniformity.

2. Chemical Fiber and Textile Industry

Plays a critical role in synthetic fiber production: Used in the spinning process for filaments/staple fibers like polyester, nylon, and polypropylene. It stably conveys molten polymer (e.g., PET chip melt) to spinning components, ensuring uniform fiber fineness, meeting strength requirements, and reducing fiber breakage.

3. Rubber Processing Industry

Supports continuous production of rubber products: Primarily used in the extrusion molding of rubber seals, hoses, and tire treads. It enables stable conveying and pressure control for viscous melts like natural and synthetic rubber, enhancing the density and dimensional stability of rubber products.

4. Composite Materials and Modified Plastics

Meeting Demanding Material Blending and Molding Requirements:

In the production of glass-fiber reinforced plastics (e.g., PA6 + glass fiber) and flame-retardant modified plastics, it works with extruders to achieve uniform mixing of melt and additives while maintaining stable output pressure, ensuring consistent performance of modified materials.

5. Other Specialized Polymer Processing

Covering high-value-added applications:

For processes like hot-melt adhesive extrusion, fluoroplastic (corrosion-resistant specialty plastic) molding, and medical-grade plastic processing (e.g., PP IV tubing feedstock), it meets stringent production requirements for specialty materials through high-precision delivery and exceptional temperature resistance and wear resistance.
