Functions, Attributes, Applications, Advantages, and Core Components of Dry Press Molded Pulp Shaping Machine
1. Functions
The dry press molded pulp shaping machine (also known as the pulp molding shaping machine) is primarily used for hot-press shaping of molded pulp products (pulp-molded items). It enhances shape stability, surface smoothness, and improves product strength and aesthetics.
2. Attributes
Processing Method: Hot-press molding
Applicable Materials: Semi-finished pulp-molded products (dried molded pulp items)
Temperature Control: Adjustable (typically 100–300°C)
Pressure Control: Hydraulic or pneumatic system with adjustable pressure
Automation Level: Manual, semi-automatic, or fully automatic
3. Applications
Packaging Industry: Used for producing eco-friendly molded pulp packaging, such as electronic product liners, food packaging, and cosmetic trays.
Industrial Cushioning Materials: Manufactures shock-absorbing molded pulp products as alternatives to plastic foam.
Disposable Tableware: Shapes pulp-molded items like plates, bowls, and cup holders.
4. Advantages
Eco-Friendly and Energy-Efficient: Utilizes biodegradable pulp materials, meeting environmental standards.
Enhanced Product Quality: Improves surface smoothness and structural density, increasing strength and durability.
High Adaptability: Capable of shaping molded pulp products of various forms and sizes.
High Production Efficiency: Automated models enable continuous production, boosting output capacity.
5. Core Components
Heating System: Electric heating plates, thermal oil heating, or steam heating devices to provide shaping temperature.
Pressure System: Hydraulic or pneumatic cylinders to deliver stable pressure for uniform shaping.
Mold System: Upper and lower molds (male and female dies) that determine the final shape of the product.
Temperature Control System: PID controllers or PLC systems for precise and stable temperature regulation.
Transmission System: Servo motors, lead screws, or hydraulic drives to control mold movement and pressure application.
Frame Structure: High-strength steel or aluminum alloy framework to ensure stability and durability.
The dry press molded pulp shaping machine is a key piece of equipment in pulp-molded production, widely used in the eco-friendly packaging industry for its efficiency, energy-saving features, and environmental benefits.
