Fully Automatic High-Speed Paper Cup Forming Machine

The Fully Automatic High-Speed Paper Cup Forming Machine is designed for continuous and stable production of paper cups with consistent forming accuracy and sealing performance. It integrates paper feeding, ultrasonic side sealing, bottom forming, rim curling, and automatic stacking into a synchronized production system.

The machine is engineered for long-hour industrial operation, maintaining stable performance under continuous load conditions. It supports single and double PE coated paper materials and is suitable for different cup sizes used in beverage and food packaging applications.

The overall design focuses on stable mechanical coordination, precise forming control, and consistent output quality during long production cycles.

Stable High-Speed Output Performance
The machine operates at 120–160 cups per minute depending on cup specifications and paper conditions, with synchronized motion control across all forming stations to maintain consistent output.

Precision Servo Feeding System
Servo-driven feeding ensures accurate paper positioning before forming, reducing alignment deviation and improving forming stability.

Ultrasonic Sealing Stability
Ultrasonic bonding technology ensures uniform sealing strength on PE coated paper without overheating, maintaining stable seam quality during continuous production.

Controlled Forming Accuracy
The forming system adopts coordinated mechanical structure design to maintain stable cup geometry and reduce dimensional deviation during long production cycles.

Reinforced Bottom Forming System
The bottom sealing structure applies controlled pressure design to ensure stable bonding strength and consistent structural integrity.

Continuous Operation Design
The machine frame and transmission system are engineered for stable long-hour operation with reduced vibration and consistent mechanical performance.

Paper Feeding: Servo-controlled feeding system delivers pre-cut PE coated paper into the forming section with precise alignment.

Side Sealing: Ultrasonic system bonds the cup seam with controlled energy output to ensure stable sealing strength.

Bottom Paper Positioning: Bottom paper is accurately positioned for precise forming alignment.

Bottom Forming: Controlled pressure system ensures stable bonding and structural consistency of the cup base.

Rim Curling: The rim forming unit shapes the cup edge evenly to improve rigidity and uniformity.

Automatic Stacking Output: Finished cups are automatically stacked for efficient downstream packaging.

The machine adopts a distinct desktop layout that isolates the mechanical drive mechanics from the forming mold stations.

Lower Compartment: All heavy transmission gears, longitudinal shafts, and high-precision cylindrical indexing cams operate within a sealed oil bath, protecting them from paper dust and moisture.

Upper Open-Top Layout: Allows technicians to perform rapid maintenance, clean the working stations effortlessly, and execute complete mold-changeovers within short operational windows.

The machine is widely applied in the production of paper cups used in:

It supports standardized production and customized cup specifications.

Sini Machinery maintains strict compliance with CE and ISO9001 international manufacturing benchmarks. Every mechanical shaft is CNC-machined from high-strength alloy steel and subjected to specialized heat treatments to maximize wear resistance and prevent long-term thermal deformation. Precision casting ensures exact fit-tolerances across multi-station indexing assemblies.

Factory Verification: Prior to shipment, each machine undergoes a rigorous 48-hour continuous stress test under full capacity to guarantee that vibration dampening, automated sensors, and pneumatic cycles operate flawlessly upon arrival at the client facility.
