Multi-Size Double PE Paper Cup Forming Machine

The Multi-Size Double PE Paper Cup Forming Machine is engineered for continuous production of double-side PE coated paper cups with multi-diameter and multi-height configuration capability on a unified forming system.

The machine is designed for production environments requiring stable output across multiple cup specifications while maintaining consistent sealing integrity on both inner and outer PE layers. The forming system integrates synchronized mechanical coordination and controlled thermal distribution to ensure stable performance during long-cycle operation.

Unlike single-specification forming systems, this solution supports structured production flexibility, enabling manufacturers to respond to diversified product requirements without compromising forming accuracy or sealing stability.

Multi-Material Compatibility
Supports Double PE coated paper, PLA, and water-based barrier coated materials for wider application coverage.

Stable Ultrasonic Sealing System
High-frequency ultrasonic bonding ensures consistent side seam strength and reliable moisture resistance while preserving surface print quality.

Fast Size Changeover System
Modular mold structure enables efficient specification switching, improving production flexibility and reducing downtime.

Heavy-Duty Mechanical Transmission System
Open cam and synchronized gear structure ensure stable mechanical timing and long-term operational precision under continuous production.

Automated Lubrication & Maintenance Design
Integrated oil circulation system reduces manual maintenance requirements and improves wear resistance of key mechanical components.

The equipment is structured as a multi-module forming system with coordinated mechanical and thermal units:

Paper feeding module: Ensures stable sheet alignment and synchronized feeding rhythm.

Rotary forming platform: Multi-station mechanical coordination for sequential cup forming.

Thermal control module: Distributed heating zones for controlled sealing stability.

Cam transmission system: Maintains synchronized motion accuracy across forming stages.

Output and stacking system: Automatic cup alignment and structured collection.

This architecture ensures stable process continuity across long production cycles.

Blanks Induction: Pre-cut paper cup blanks are fed via synchronized vacuum suction into the primary forming station where the ultrasonic system welds the vertical seam.

Bottom Integration: Bottom-roll paper automatically indexes into the punching matrix, cutting and inserting the bottom disk into the formed cone.

Localized Heating & Knurling: Focused hot-air stages pre-heat the bottom lip before a mechanical knurling tool applies uniform pressure to form a permanent, leak-proof moisture barrier.

Top Lip Curling: The cup rim undergoes a regulated dual-stage curling process to create a smooth, rigid top edge, after which finished cups are pneumatically discharged into the counting stacker.

The system supports structured configuration based on production requirements:

Each machine is validated through structured inspection processes:

This ensures stable forming performance under continuous production conditions.
