cap pe foam extruder melt pump and screen changer

The melt pump and screen changer for the PE foam cap extruder are vital components in the extruder production line, each fulfilling critical functions. Below is a detailed introduction to both:

I. Melt Pump for PE Foam Cap Extruder

1. Functions and Applications

The melt pump is primarily used for pressure boosting and stable flow delivery of medium to high-viscosity polymers in extruders. In the production line of the PE foam cap extruder, the melt pump ensures the stability and consistency of the melt during transportation, thereby enhancing product quality and production efficiency.

2. Technical Features

High Temperature and Pressure Resistance: Capable of operating under high temperature (e.g., 350°C) and pressure (e.g., 35MPa) conditions, meeting the specific needs of the PE foam cap extrusion process.

Optimized Flow Channel Design: Prevents dead zones within the flow channel, reducing material residue and improving product quality.

Improved Gear Parameters: Enhanced gear parameter design ensures more stable output pressure with lower pulsation rates, suitable for precision extrusion.

Excellent Material Quality: Made from high-temperature alloy steel and other premium materials, it boasts good wear resistance and long service life.

Versatile Installation Methods: Offers suitable installation options based on varying customer site conditions, ensuring flexibility and practicality.

II. Screen Changer for PE Foam Cap Extruder

1. Functions and Applications

The screen changer is primarily used for melt filtration in extrusion lines, removing impurities and contaminants from the melt to ensure product purity and quality. In the PE foam cap extruder, the screen changer enables filter screen replacement without halting production, maintaining continuity and stability in the production process.

2. Technical Features

Integrated Design: Adopts an integrated design to optimize equipment space and energy consumption, enabling filter screen replacement without stopping the machine.

Superior Material Quality: The main body of the screen changer is crafted from specially formulated alloy materials through rigorous forging, surface heat treatment, and precise metalworking processes, ensuring stability and durability.

Excellent Sealing Performance: A well-designed sealing structure prevents leakage and penetration under high temperature and pressure conditions, effectively reducing screen changing resistance.

Alternating Operating Mode: Utilizes an alternating operating mode to guarantee continuous and stable material flow during screen changing, ensuring reproducibility of process parameters.

High Pressure and Temperature Resistance: The screen changer possesses high pressure and temperature resistance, enabling stable operation under harsh conditions.

In conclusion, the melt pump and screen changer for the PE foam cap extruder play crucial roles in the extrusion production line. Through their synergistic effect, they ensure product quality and production efficiency. When selecting and using these components, it is essential to configure and select them based on specific production requirements and operating conditions.
