What Is a Capping Machine?

A capping machine also known as Capper is a high-precision packaging device designed to securely tighten or seal various types of caps, ensuring consistent torque, leak prevention, and product integrity. It is an essential component in automated packaging lines across the food, cosmetics, pharmaceutical, and chemical industries.

1. Core Functions

  • Automatic Capping: Automatically positions, places, and tightens caps, increasing production efficiency.

  • Adjustable Torque Control: Adapts to different cap materials, ensuring secure sealing without damaging bottles or caps.

  • Leak & Tamper Prevention: Maintains product safety and integrity.

  • User-Friendly Operation: Touchscreen or PLC control for easy parameter adjustments.

  • Multi-Bottle Compatibility: Supports round, square, and irregular containers.

  • Line Integration: Seamlessly connects with filling, labeling, and inspection equipment for fully automated production.

2. Types of Capping Machines

By Mechanism:

  • Mechanical: Rotary head or arm; suitable for screw caps and CRC caps.

  • Pneumatic: Air cylinder-driven torque; suitable for dropper caps and pump heads.

  • Servo-Controlled: Programmable precision torque; ideal for high-end cosmetic closures.

  • Friction-Based: Soft rollers for gentle grip; suitable for spray caps or flexible lids.

  • ROPP (Roll-On): Rolls threads on aluminum wine caps; forms tamper-evident rings.

  • Press Capping: Vertical pressure sealing; suitable for flip-off vial caps.

By Automation Level:

  • Manual: Hand-fed, low-cost; suitable for laboratories or small-batch production.

  • Semi-Automatic: Automatic capping with manual feeding; suitable for SMEs.

  • Fully Automatic: Automatic bottle feeding, capping, and discharge; ideal for high-speed lines.

  • Integrated Multi-Function Systems: Combines filling, capping, and labeling; saves space and improves efficiency.

Cap & Container Compatibility

  • Cap Types: Screw caps, ROPP aluminum caps, dropper caps, pump heads, spray caps, flip-off vial caps, decorative perfume caps.

  • Container Types: Plastic bottles, glass bottles, metal cans, small pharmaceutical vials (2–30ml), wine bottles (50–1000ml), irregular cosmetic containers.

  • Adaptable Clamping & Torque Systems: Ensures stable and secure capping for different bottle shapes and materials.

Special Applications & Custom Solutions

  • Perfume Bottles: Glass bottles with spray pumps or decorative caps; require gentle torque and precise alignment. ZONESUN provides 30–100ml integrated filling, capping, and labeling solutions.

  • Wine Bottles & ROPP Caps: Roll-on threading creates tamper-evident seals; ZONESUN offers multi-head ROPP systems with interchangeable tooling.

  • Pharmaceutical Vials & Ampoules: Aluminum cap pressing over rubber stoppers; GMP-compliant integrated filling, stoppering, and capping systems with optional vision inspection.

Expandable Features & Line Integration

  • Cap Sorting Systems: Vibratory bowls and elevators for automatic feeding.

  • Bottle Orientation Modules: Automatic unscramblers ensure smooth capping.

  • Production Line Integration: Connects with filling, labeling, coding, and inspection machines.

  • Smart Control Systems: PLC + HMI with torque feedback and error detection.

  • Vision Inspection: Real-time monitoring of cap presence, alignment, and sealing integrity.
