The fully automatic polyethylene hot and cold pressing production line is designed for the batch molding of large polyethylene products. It integrates automatic mold transfer, hot pressing, cold pressing, mold opening, part handling, inspection, and finished-product transfer into one automated system.
Centered on 4,600-ton servo hot-press and cold-press molding machines, the line is equipped with mold-changing trolleys, gantry manipulators, vacuum suction cups, automatic positioning, and AGV transfer systems. All stations operate in coordination, enabling continuous automated production from material loading to finished-product offloading.
PRODUCT DESCRIPTION
Mold loading → Automatic transfer → Automatic cover plate placement → 4,600-ton servo hot pressing → Automatic mold changing → 4,600-ton servo cold pressing → Automatic mold opening → Ejection → Vacuum suction cup part removal → Product inspection → AGV transfer → Mold return
4,600-ton Servo Hot-Press Molding
After the mold automatically enters the hot press and completes positioning, the equipment executes the following steps in sequence according to the set program:
Rapid mold closing → Slow mold closing → Pre-pressing → Heating → Stepped pressure application → Pressure holding
Process parameters such as pressure, temperature, speed, position, and pressure-holding time can be set according to product requirements, meeting the hot-press molding process needs of different polyethylene products.
4,600-ton Servo Cold-Press Setting
After hot pressing is completed, the mold-changing trolley automatically transfers the mold to the cold press to complete rapid mold closing, slow mold closing, pressure application, and pressure-holding setting.
After cold pressing is completed, the mold is automatically transferred to the mold-opening station. The gantry manipulator removes the cover plate, the ejection mechanism raises the product to a specified height, and the vacuum suction cups automatically complete part removal.
1. Automatic connection between hot pressing and cold pressing: The 4,600-ton hot press and the 4,600-ton cold press form a continuous molding system.
2. Automatic transfer of large molds: The mold-changing trolley automatically completes mold push-in, pull-out, positioning, and station transfer.
3. Servo process control: Supports multi-stage molding processes such as pre-pressing, stepped pressure application, and pressure holding.
4. Automatic gantry pick-and-place: Automatically completes the pick-and-place of mold cover plates and the gripping of molded products.
5. Automatic detection and alarm: A product inspection system can be configured to provide timely alarms when abnormalities are detected.
6. AGV automated logistics: After finished products reach a set quantity, they can be automatically transferred to the unloading area by AGV.
7. Continuous cyclic production: The mold automatically returns to the cleaning and loading station, reducing manual handling and process waiting.
Suitable for the batch production of large polyethylene products, thermoplastic material products, and other products requiring hot-press molding + cold-press setting processes.
The hydraulic press tonnage, worktable size, heating system, mold-changing system, manipulator, and AGV logistics system can be customized according to product size, mold weight, molding pressure, temperature, production cycle time, and automation requirements.
