micro extruder melt pump

The Micro Extruder Melt Pump is a melt conveying device specifically designed for small or micro extruders, primarily used for pressurizing, stabilizing, and accurately metering high-temperature, high-viscosity polymer melts. Below is a detailed introduction to the Micro Extruder Melt Pump:

I. Functional Characteristics

Pressure Boosting & Stabilization: The Micro Extruder Melt Pump significantly enhances the pressure of the melt while maintaining its stability, which is crucial for improving the quality of extruded products.

Precise Metering: Leveraging high-precision gear clearance and volumetric construction, the pump ensures accurate metering of the melt, minimizing errors in the production process.

Versatile Applicability: It is compatible with various high-temperature, high-viscosity polymer melts such as PE, PP, PET, PVC, and is widely used in the extrusion molding processes of plastics, resins, rubbers, and other industries.

II. Structure & Materials

Structural Composition: The Micro Extruder Melt Pump typically comprises a pump casing, front and rear covers, gear shafts, sliding bearings, and shaft seals. It operates by intermeshing gears to form a working volume for melt conveyance.

Material Selection: Key components like the pump body and gears are often made of high-temperature tool steel or nitrided steel to ensure stability and durability in high-temperature, high-pressure environments.

III. Application Areas

The Micro Extruder Melt Pump is widely applied in small or micro extruder production lines, particularly excelling in the following areas:

Pelletizing & Film Production: During plastic pelletizing and film production, it provides stable melt flow rates and pressures, ensuring product quality.

Pipe & Sheet Extrusion: It plays a vital role in the extrusion molding of pipes and sheets, enhancing production efficiency and product precision.

Laboratory & Research & Development (R&D): Due to its small size and portability, it is also frequently used in laboratories and R&D settings for extrusion testing and process research of high-molecular-weight materials.

IV. Purchase & Maintenance Recommendations

Purchase Recommendations: When selecting a Micro Extruder Melt Pump, prioritize products from reputable manufacturers. Pay attention to performance parameters (e.g., working pressure, flow range, materials) and after-sales service quality. Choose the appropriate model and specifications based on actual needs.

Maintenance Recommendations: Regular maintenance and servicing are crucial for ensuring long-term stable operation. It is recommended to periodically inspect the pump's seal integrity, lubrication system, and temperature control system. Promptly clean and replace worn parts. Additionally, adhere to operating procedures and safety regulations to prevent equipment damage or accidents caused by improper operation.

In summary, the Micro extruder hot melt dosing pump plays a significant role in small or micro extruder production lines, notably enhancing production efficiency and product quality. When selecting and using this equipment, comprehensive consideration should be given to product performance, after-sales service, and maintenance requirements.
