Product Overview
The Medium Speed Single PE Paper Cup Machine is an industrial forming system designed for stable and continuous production of single-side PE coated paper cups.
It integrates paper feeding, thermal sealing, bottom forming, knurling reinforcement, rim curling, and automatic stacking into a synchronized mechanical cycle. Each forming station operates under fixed timing control, ensuring stable geometry consistency during long production runs.
This model is designed for manufacturers requiring controlled output, predictable production scheduling, and flexible cup size adaptation without compromising forming stability.
Unlike basic forming equipment, this system is engineered around mechanical synchronization precision, ensuring stable performance under continuous 24-hour industrial operating conditions.
Core Product Advantages
High-Stability Open-Cam Drive System
The machine adopts an open-cam indexing structure with heavy-duty gear transmission, replacing chain-based systems. This ensures stable mechanical timing, reduces wear, and lowers long-term maintenance requirements.
Hot Air Side Sealing System
Imported hot air technology ensures uniform thermal distribution across the PE coating, achieving firm sealing without damaging paper structure and preventing leakage risk.
Precision Micro-Lubrication System
An automated oil-mist lubrication system delivers controlled lubrication to moving components, reducing contamination risk on finished cups while extending mechanical service life.
PLC Control with Touchscreen Interface
A programmable logic controller (PLC) manages full-cycle operation. Real-time data including speed, output, and system status is displayed on a multilingual touchscreen for simplified monitoring and control.
Vertical Rotary Multi-Station Structure
The compact rotary layout ensures consistent synchronization across all forming stages while optimizing factory floor space utilization.

Machine Structure
Paper feeding and positioning system
Side sealing and thermal bonding unit
Bottom forming and pressure system
Knurling reinforcement module
Rim curling and automatic stacking system
Each module operates under a unified mechanical timing system to maintain stable synchronization across the full production cycle.
Working Principle
The production cycle follows a fixed mechanical sequence:
Automatic paper feeding → side seam thermal sealing → cylindrical cup forming → bottom paper insertion and pressing → structural knurling reinforcement → rim curling → automatic stacking output
All stages are synchronized by a central cam drive system, ensuring identical forming timing across continuous cycles.
Applications
This system is suitable for:
- Hot beverage paper cups (coffee, tea, milk drinks)
- Cold drink paper cups for food service operations
- Takeaway beverage packaging production lines
- Medium-scale cup manufacturing facilities
- Flexible multi-size production environments
Custom Engineering Options
The machine can be configured according to production requirements:
• Cup size tooling configuration
• Heating system adjustment (thermal / ultrasonic options)
• Electrical system customization
• Output stacking configuration
• Production line integration interface
Manufacturing Standard Control
Production follows structured engineering control systems covering:

Packaging & Delivery
For international transportation, each machine is protected with:
Anti-corrosion surface treatment
Shock-resistant protective wrapping
Structural fixation for transport stability
Reinforced export wooden packaging
All units are secured to maintain mechanical alignment during long-distance shipment.
Frequently Asked Questions
Q: How does this machine prevent cup bottom leakage?
A: Sini Machinery resolves bottom leakage by using a dual-stage bottom pre-heating system combined with a rigid mechanical cam-driven knurling tool. This ensures uniform thermal bonding and precise pressure distribution across the entire circumference of the cup bottom, delivering a reliable seal.
Q: Can this machine handle both Single PE and Double PE coated paper?
A: This specific model is structurally optimized and thermally tuned for Single PE coated paper, which is ideal for hot drinks. For Double PE paper applications, which require ultrasonic sealing for the side seam, please review our specialized Double PE machine series.
Q: How long does it take to change molds for a different cup size?
A: A complete mold swap and calibration take approximately 4 to 8 hours by a trained technician. The modular design of our stations allows operators to swap the mandrels, bottom cutters, and curling dies efficiently, minimizing operational downtime.
Q: What regular maintenance is required to maintain the 70-90 pcs/min speed?
A: Daily maintenance involves clearing paper dust from the optical sensors and checking the automated oil-mist levels. Weekly checks include inspecting the hot air nozzles for debris and verifying cam lubrication. Adhering to this routine ensures the machine maintains its rated speed continuously without premature mechanical wear.
