4 HEAD Screw Capping Machine Assembly in West Bengal

Frequently Asked Questions

• What is a 4 HEAD Screw Capping Machine Assembly?

  It is an automatic four-head capping machine and assembly used to tighten and seal screw-type caps on bottles at high speed in continuous packaging lines.

• Which industries commonly use this machine?

  Pharmaceutical, food and beverage, edible oil, cosmetic, agrochemical, and chemical plants use four-head screw capping machines for medium to high production volumes.

• How does this differ from a single-head machine?

  A four-head machine can cap multiple bottles simultaneously, giving significantly higher output and better line efficiency compared with single-head units.

• What is the typical production capacity?

  Four-head screw capping machines are generally designed for medium–high speeds, with output commonly several thousand bottles per hour depending on bottle size and cap type.

• What types of caps are supported?

  The assembly is suitable for plastic or metal screw caps and can be configured with different chucks and change parts to suit various cap diameters.

• Which bottle types can be handled?

  It can work with PET, HDPE, glass, and similar bottles, provided their neck finish and height are within the adjustment range of the machine.

• How does the 4-head screw capping operation work?

  Bottles are conveyed under the four capping heads; each head descends, grips the cap, applies preset torque, and then returns while the conveyor indexes the next set of bottles.

• How is torque and bottle height adjusted?

  Torque is usually set through mechanical or clutch-based systems on each head, while a height-adjustable column allows alignment of the heads with different bottle heights.

• Can one machine handle multiple bottle and cap sizes?

  Yes, by changing chucks, star wheels, guides, and adjusting height and format settings, the same machine can run multiple bottle and cap combinations.
