Automatic Capping Machines
Ensuring a leak-proof and tamper-evident seal is critical for product integrity and consumer safety. Harsiddh Unimach provides a comprehensive range of high-performance Automatic Capping Machines engineered to handle diverse closure types, including screw caps, ROPP caps, press-on caps, and measuring cups. Our machinery is designed for seamless integration into high-speed bottling lines across the pharmaceutical, cosmetic, beverage, and chemical industries.
Our Capping Machine Range
- Automatic Rotary Capping Machine: High-output systems utilizing multi-head configurations for consistent torque and high-speed sealing of plastic and glass bottles.
- Automatic ROPP Capping Machine: Specifically designed for aluminum roll-on pilfer-proof (ROPP) capping, ideal for the pharmaceutical and liquor industries.
- Automatic Screw Capping Machine: Features adjustable torque heads to securely fasten plastic screw caps without damaging the threads or the container.
- Automatic Measuring Cup Placer: A specialized unit that precisely places and presses measuring cups onto filled and capped bottles.
- Automatic Linear Capping Machine: A versatile, easy-to-adjust solution for lines that handle a wide variety of bottle shapes and cap sizes with minimal changeover.
Salient Features
- Precision Torque Control: Equipped with magnetic or mechanical torque clutches to ensure every cap is tightened to the exact specification, preventing leaks or over-tightening.
- No Bottle – No Cap System: Intelligent sensors prevent cap wastage and machine jams by ensuring a cap is only released when a container is detected.
- cGMP Compliant Build: Manufactured from high-grade SS 304 with a matt finish and SS 316 contact parts, meeting stringent global hygiene standards.
- Universal Compatibility: Effortlessly handles various container materials (PET, HDPE, Glass) and closure types (Screw, Flip-top, ROPP, CRC).
- Automatic Cap Feeder: Includes a bulk hopper and vibratory or centrifugal elevator to orient and feed caps automatically to the capping head.
- Synchronized Operation: Integrated PLC and HMI allow for precise speed synchronization with upstream filling and downstream labeling equipment.
- Safety Interlocks: Features acrylic safety guards and emergency stops to ensure operator protection during high-speed operation.
Frequently Asked Questions
How do you prevent damage to the caps during the tightening process?
Our machines utilize adjustable magnetic torque clutches. Once the pre-set tightness is reached, the head slips, ensuring the cap is secure without scuffing the plastic or stripping the threads.
What happens if a bottle is missing on the conveyor?
Every Harsiddh Unimach capping machine is equipped with a "No Bottle – No Cap" sensor. If no bottle is detected at the pick-up station, the machine will not release a cap, preventing wastage and potential jams.
How difficult is it to change parts for a different bottle size?
The machines are designed for rapid changeover. Usually, only a few parts like the star wheel and bottle guides need to be replaced. These are tool-less or require minimal tools, allowing for a complete changeover in under 20 minutes.
Is the machine compatible with different cap shapes, like flip-tops or CRC?
Yes. By using specialized cap feeders (vibratory bowls) and custom-designed capping chucks, our machines can handle child-resistant closures (CRC), flip-top caps, and even non-standard geometric shapes.
