Cap Tightening Machine

The fully automatic Cap Tightening Machine sets pre-threaded caps onto the bottle opening and then screws it to a pre-set level of torque. This is achieved with an adjustable torque tightening head. Accuracy on the level of torque applied is ensured through the use of Magnetic Clutch System.


  • Equipped with adjustable torque magnetic tightening head
  • Automatic cap feeding system using a cap hopper (vibrating bowl with adjustable vibration frequency) to accommodate regularly-shaped caps
  • Intermittent capping operation
  • Cam-controlled timing and operation sequencing for consistent and reliable performance
  • Main drive protected by a safety clutch mechanism
  • Capping speed can be adjusted through electronic control
  • No bottle, no capping operation
  • Machine body cover and conveyor made of stainless steel 304
  • Sanitary conveyor design for easy cleaning and maintenance

Output rate:

  • up to 70 bottles per minute (bpm) for single head and 120 bpm for double head


  • ideal for 10ml – 500ml regularly-shaped glass and sturdy plastic bottles


  • Pharmaceutical, Cosmetic, Veterinary, Chemicals, Beverage
