Single-plate screen changer configuration
The configuration of the single-plate screen changer must be selected based on specific process requirements, including core components and parameters. The key configurations include the following:
Core Components
Main Structure: Utilizes flexible pressure-activated sealing technology to ensure the seal automatically activates and compensates with melt pressure, suitable for high-viscosity materials.
Hydraulic System: Compatible with a accumulator hydraulic station to achieve rapid screen changing (2-5 seconds), enabling uninterrupted operation without material leakage.
Heating Method: Options include external heating plates, internal heating tubes, or thermal fluid heating to meet different material temperature requirements (up to 300°C).
Technical Parameters
Working Pressure: ≤50 MPa, suitable for melt viscosities of 100–40,000 Pa·s.
Filter Precision: Filter mesh size can be selected according to requirements.
Selection Criteria
Consideration should be given to factors such as production capacity, material composition, and equipment pressure. For example:
Highly corrosive materials require corrosion-resistant materials.
Mobile applications can be configured with a mobile cart integrated with a hydraulic station and electrical control system.
Typical application scenarios include direct connection between the extruder and mold, supporting dual-station alternating operation to enhance production efficiency.
