Lug capping machine

Types of lug capping machines

The lug capping machine is designed to apply food-grade metal caps with internal coatings to glass bottles. According to different production demand, there are various types of this machine.

• Manual lug capping machines

  The manual capper is a machine that manually places the cap on the bottle. This machine usually has no power and only used human strength to push the control lever to put the cap on the bottle. It is an inexpensive option for small, start-up companies or those looking to cap bottles in lower volumes. Although it may not be practical for larger volume bottling lines where speed is essential, it does offer the ability to cap bottles of any shape and size.

• Pedal lug capping machines

  The pedal-operated capping machines allow the operator to position the bottle and the cap, and with a simple press on the foot pedal, the cap is applied to the bottle. This machine gives operators a safe and efficient capping method and reduces the physical exertion required compared to hand capping.

• Manual lever lug capping machines

  The manual lever-operated capping machines are similar to the manual push models but allow for more leverage and capping force by using a manual lever. This type of machine is affordable and efficient for small production but not practical for high-volume bottling lines.

• Electric lug capping machines

  The electric lug capping machine is more efficient than manual/air machines, which offers more production efficiency. This machine can be adjusted to cap 200-300 bottles/hour depending on the staff's operational skills, production line layout, and other factors. It is energy-efficient, saving physical power during production compared to manual and air-powered machines.

• Pneumatic lug capping machines

  The pneumatic capping machine is ideal for limiting the potential of dust entering the machine and bodily injury. It provides a higher production capacity than manual and electric machines and is faster in bottling lines. This machine is perfectly used in the food, beverage, and chemical industries.

Specification and maintenance of lug capping machines

Specifications

• Production speed: The production speed of lug capping machines can vary depending on the model, features, and size. Generally, manual machines operate at a speed of 10-25 bottles per minute, while semi-automatic machines can handle 30-60 bottles per minute. The speed of fully automatic lug capping machines is much faster, ranging from 100-300 bottles per minute.
• Applicable bottle sizes: The applicable bottle sizes of lug capping machines also vary by machine type. Generally, manual machines can cope with bottles with 26mm-48mm diameter lids. Semi-automatic and fully automatic machines can adapt to more extensive and larger bottles, including those that are not round in shape.
• Material and power: Standard stainless steel is usually used for the main body and parts of the lug capping machine. The power sources of these machines include electric, pneumatic, and hydraulic power, which may vary depending on the specific model and type.

Maintenance

• Clean and maintain: Clean the machine surface and parts to remove any dirt and residues. Use a mild detergent and warm water to clean the machine, then dry it thoroughly. Be careful not to wet the electrical components.
• Lubrication: Lubrication is required for moving parts such as gears, bearings, etc. Lubricating oil or grease should be applied according to the instructions to ensure smooth operation.
• Check the working state of the machine: Regularly check the fastening state of the parts, belts, etc. to ensure that they are not loose or worn. If any parts are loose or worn, adjust or replace them in a timely manner.
• Pay attention to the environment: Keep the operating environment of the lug capping machine clean and tidy, away from dust, moisture, flammable and explosive substances, etc., to avoid damaging the machine.
• Regular maintenance: Develop a regular maintenance schedule to check and repair key parts of the machine on a regular basis, such as replacing lubricants, cleaning and adjusting, etc., to extend the service life of the machine.

Uses of the lug capping machine

The lug capping machine is used for various applications in the food and beverage industry. Here are some of them:

• Sealing Glass Bottles: This machine is commonly used to seal glass bottles containing carbonated beverages such as beer, soda, sparkling water, and soft drinks. It ensures that the bottle caps are securely fastened, maintaining the beverage's freshness, carbonation, and shelf life.
• Food Jar Sealing: The lug capper is employed in food processing and packaging industries to seal jars containing preserved fruits, pickles, sauces, condiments, caramel sauce, jams, and other food products. It provides an airtight seal that helps preserve the food's quality and prevents contamination.
• Cider and Kombucha Bottling: In the production of cider, kombucha, and other fermented beverages, the lug capping machine is used to cap the bottles after fermentation and flavoring. It ensures proper sealing during distribution and retail.
• Small-Batch Craft Bottling: Some craft breweries, wineries, and food artisans use lug capping machines for small-batch bottling. This applies to when they want to produce limited editions, homemade beverages, or gourmet food products that require lug caps for branding or quality control.

How to Choose Lug Capping Machines

When purchasing a bottle capping machine for the bottles of goods produced, there are several things to keep in mind, including the materials, types, sizes, customization possibilities, and delivery and logistics solutions of the machines.

One of the most crucial aspects to take into account is the machine's production capacity per hour or per day because it must meet the bottle capping demand in the production line. Capping speed, adjustable settings for encapsulation volume and feeding speed, and the number of workers required to operate the machine all have an impact on the production rate. Capping speeds of 30 to 100 bottles per minute are typical for semi-automatic machines, while 250 to 600 bottles per minute are typical for automatic machines. Choose a machine that suits the number of bottles that need to be capped in a day to avoid bottlenecks in the production line or unnecessary expenditure on a machine that is too large for the requirement.

Check that the capping machine's bottle compatibility—that is, the sizes, shapes, and materials it can cap—matches the bottles used in the production line. For instance, glass bottles require a different type of cap than plastic ones, and irregularly shaped bottles may need customized bottle grip to hold the bottle while capping.

The amount of maintenance needed by the capping machine is also an important factor to consider in determining whether it is cost-effective to purchase. Consider the machine's maintenance requirements, including any necessary periodic part replacements and the availability of repair services. Determine whether the machine's operating manual and documentation are readily available and if staff training will be necessary.

Finally, the machine's cost and the shipping expenses from the seller's location to the destination should be taken into account to stay within budget and avoid any additional costs or delays in shipping. The machine's warranty period and its coverage under insurance during shipping are also essential to understand in case of any damage during transit. Having clarity on the delivery and logistics will help to cap the bottles of goods at stock and sell them to gain profit.
