Automatic Bottle Lug Capping Machine
Reliable Vacuum Sealing for Food & Beverages
The Harsiddh Automatic Bottle Lug Capping Machine (HLC-100) is the industry standard for sealing glass jars and bottles with “twist-off” caps. Ideal for jams, sauces, pickles, honey, and juices, this machine provides the consistent torque necessary for long shelf-life products. Its robust, vibration-free design ensures trouble-free performance in high-volume production environments across the food, pharmaceutical, and chemical sectors.
Reliable Operational Workflow
The machine manages a continuous, high-speed automated cycle with mechanical precision.
Sequence of Operation:
- Index-Feed Entry: Containers are indexed into the rotary star wheel via a mechanical stopper that manages incoming flow.
- Synchronized Pick-up: As jars pass the delivery chute, they pick up a pre-oriented lug cap from the vibratory feeder.
- Lug Sealing: The capping head engages with the cap, applying a specific torque to “lock” the lugs onto the bottle threads.
- Fault Detection: Continuous sensors scan for “No Bottle” or “No Cap” scenarios, triggering an instant motor halt to prevent errors.
- Discharge: Sealed jars are moved smoothly along the SS slat conveyor for downstream sterilization, labeling, and secondary packaging.

Frequently Asked Questions
How does the machine ensure a vacuum-tight seal for food preservation?
For products that require long shelf lives, the Harsiddh Automatic Lug Capper can be equipped with a Steam Injection System. By injecting steam into the headspace of the jar just before capping, it displaces the air. Once the jar cools, the steam condenses, creating a vacuum seal that preserves the freshness and safety of the food.
Can the machine handle different jar sizes and cap diameters?
Yes. The machine is designed for high flexibility. It can accommodate a wide range of jar heights and diameters (typically from 30mm to 100mm cap sizes). The capping belts and guide rails are easily adjustable, and changeover parts like the cap chute and star-wheels can be swapped quickly to handle different production runs.
How does the automatic cap feeding and orientation work?
The machine features an integrated Cap Elevator or Vibratory Bowl Feeder. This system automatically sorts the lug caps, ensures they are facing the correct direction, and feeds them into the capping zone. The "No Jar – No Cap" sensor prevents cap wastage by ensuring a closure is only released when a container is in position.
What is the construction quality and production speed of this machine?
As a cGMP-compliant model, the machine is built with a robust SS 304 stainless steel frame. All parts that come into contact with the jars or caps are made from corrosion-resistant materials. Depending on the configuration (Linear or Rotary), the machine can achieve speeds ranging from 30 to 120 jars per minute, making it suitable for high-speed food processing lines.
