Product Overview
The Energy-Saving Double PE Paper Cup Machine is an industrial forming system designed for continuous production of double-side PE coated paper cups used in hot and cold beverage applications.
The machine integrates a segmented thermal control system and synchronized mechanical transmission architecture. Heating output is distributed according to forming stages rather than constant full-load operation, allowing stable production while optimizing energy utilization during long-cycle manufacturing.
For large-scale paper cup production environments, the system supports consistent sealing performance, stable forming accuracy, and controlled operating cost across multi-shift production schedules.
Key Features & Technological Advantages
Dual-Station Ultrasonic Side Sealing System
High-frequency ultrasonic bonding technology is applied to achieve instant sealing of double PE coated paper. This ensures strong seam integrity, water-tight performance, and stable output quality even under continuous high-speed operation.
Open-Cam Precision Drive System
The machine adopts a heavy-duty open-cam transmission structure with an integrated oil circulation lubrication system.
Compared with chain-driven systems, it provides
• Improved transmission stability
• Reduced mechanical wear
• Higher long-term timing accuracy
• Lower maintenance requirements
Servo-Controlled Paper Feeding System
A servo-driven feeding system precisely controls web advancement during punching and forming processes. This minimizes material waste and improves raw material utilization efficiency.

Working Process Overview
The machine operates on a rigid cast-iron frame structure to ensure vibration stability and long-term precision.
Blank Feeding & Side Sealing: Paper blanks are automatically fed and sealed using ultrasonic bonding.
Bottom Forming: Bottom discs are punched and inserted with controlled alignment.
Localized Heating & Knurling: Targeted heating softens PE layers, followed by mechanical knurling for sealing reinforcement.
Top Curling & Output: Cup rims are shaped through multi-stage curling before automatic stacking and discharge.
Industrial Applications
This versatile, high-stability equipment supports the global food packaging supply chain by manufacturing a wide range of secure commercial containers:
Condensation-Resistant Cold Cups: Designed for iced beverages, sodas, and ice cream tubs, preventing the outer paper walls from softening in humid or freezing environments.
Thermal-Insulated Hot Cups: Engineered to withstand high-temperature liquids without structural breakdown or aromatic interference.
High-Fat Dairy & Yogurt Tubs: Delivers tight, uniform seam integration to meet strict liquid-retention requirements for dairy packaging.

Frequently Asked Questions
Q: How does the machine achieve up to 20% energy savings?
A: Energy reduction is driven by our segmented, zoned heating elements combined with an optimized mechanical drive. Instead of utilizing energy-intensive hot-air arrays, heat is applied locally and precisely at the exact sealing zones, lowering overall electrical draw.
Q: Can a single machine manufacture multiple cup sizes?
A: Yes. The machine features a modular design framework. By exchanging the forming mandrels, knurling heads, and curling dies, a single machine can be configured to produce cup volumes ranging from 2 oz up to 16 oz to match your specific engineering drawings.
Q: What are the maintenance advantages of the open-cam system?
A: The open-cam mechanism runs within a continuous oil-recirculation loop that cools and lubricates all internal load-bearing parts automatically. This design eliminates manual greasing routines, reduces operational downtime, and protects food-grade paper from lubricant exposure.
