2026-02-03 Thermosensitive PVC Melt Gear Pump for Extrusion
In the field of plastics processing, PVC (polyvinyl chloride) is widely used in the production of pipes, sheets, films, and other products due to its excellent properties. However, PVCs thermosensitive nature results in a narrow processing window, making it highly sensitive to temperature fluctuations. Localized overheating can easily cause decomposition, carbonization, or even the formation of scorch, severely impacting product quality and production line continuity. Addressing this industry challenge, Batte Machinery leverages its deep understanding of material properties and extensive techn
2026-01-29 Precision Extrusion Melt Gear Pump for PVC
In the field of plastics processing, polyvinyl chloride (PVC) is widely used in the large-scale production of various products such as pipes, sheets, films, and profiles due to its excellent mechanical properties, corrosion resistance, and cost advantages. However, PVCs inherent heat-sensitive nature creates an extremely narrow processing window. It exhibits high sensitivity to temperature fluctuations during processing, making it prone to decomposition and carbonization due to localized overheating. This can lead to charring defects, severely compromising the final products appearance and per

2025-12-26 TPU extrusion melt pump and single plate screen changer
TPU extrusion melt pumps and screen changers are critical equipment in the TPU production process, performing the vital functions of pressurization, pressure stabilization, metering, and impurity filtration respectively. Function: Typically installed between the extruder outlet and the die head, the TPU extrusion melt pump primarily pressurizes, stabilizes, and meters the TPU melt. This ensures stable and precise delivery of the TPU melt to the die head, thereby guaranteeing product quality and dimensional accuracy. Features: TPU melt pumps operate under high-pressure (40MPa) and high-viscosit
2025-12-24 Plastic extrusion melt gear pump
Plastic extrusion melt pumps are critical equipment used in the plastic extrusion molding process for conveying, pressurizing, and metering high-temperature plastic melts. Working Principle A plastic extrusion melt pump is a positive displacement conveying device primarily composed of a pump housing, drive gear, and driven gear. The tooth profiles of the two gears, the pump body, and the side cover plates form the pumps feed zone, conveying zone, and discharge zone. When the gears rotate in the specified direction, the melt enters the gear tooth pockets in the feed zone. As the gears turn, the

Melt pumps (melt gear pumps) play a central role in sheet extrusion production lines by stabilizing pressure and flow while enhancing plasticization quality. They are compatible with extrusion processes for various sheet materials including PP, PE, PET, PVC, and ABS, and are particularly suited for high-precision sheet production scenarios demanding wide widths and strict thickness tolerances. Precise Flow and Pressure Stabilization The extruder screws conveying action exhibits periodic fluctuations. The melt pump utilizes the volumetric delivery characteristic of gear meshing to control extru

PE water-ring pelletizing melt pumps are predominantly gear-type melt pumps, serving as the core supporting equipment for PE water-ring pelletizing production lines. Installed between the extruder outlet and the pelletizing die, they are specifically engineered to accommodate the high-temperature, high-viscosity characteristics of PE melt. The following sections provide a detailed overview from three perspectives: core functions, key features, and selection and maintenance: Core Function Pressure and Flow Stabilization for Granulation Precision: When PE melt exits the extruder, pressure and fl
2025-12-13 Why has the melt pump outlet pressure decreased?
The core reasons for reduced melt pump outlet pressure can be categorized into three types: insufficient feed supply at the inlet end, pump body malfunction, and reduced load at the outlet end. Detailed analysis follows: Insufficient Feed Supply at the Feed End Extruder Feeding/Plasticizing Abnormalities: Material shortage in the extruder hopper, screw wear reducing conveying capacity, or poor raw material plasticization (low temperature, excessive moisture content) can cause material shortage on the melt pumps suction side, preventing sufficient pressure buildup.
