CHOOSE BY CAPPING METHOD

Choose the Right Lug Cap Capping Method

Match the capping process to your metal lug cap, glass jar, product and sealing requirements.

Standard Twist-Off Capping

Applies and tightens compatible metal lug caps when a dedicated vacuum capping process is not required.

Mechanical Vacuum Capping

Uses mechanical vacuum extraction during capping for suitable jars and products without a steam process.

Steam Vacuum Capping

Combines steam treatment and twist-off cap application for compatible jars, caps and filling processes.

BEFORE CHOOSING A MACHINE

Key Details for Machine Selection

Accurate jar and cap information helps determine machine compatibility and the right line configuration.

Jar & Neck Dimensions

Jar material, body diameter, height, neck finish and opening size.

Metal Lug Cap

Cap diameter, lug structure, liner design and physical samples.

Product & Filling Process

Product characteristics and whether filling is hot or cold.

Sealing Requirement

Standard cap application or a specified vacuum capping process.

Target Output

Required production speed and planned hours of operation.

Automation Level

Standalone capping or integration with filling, labeling and packing.

For accurate matching, provide physical jar and cap samples for testing.

FROM EMPTY JAR TO FINISHED PACKAGE

FREQUENTLY ASKED QUESTIONS

Lug Cap Capping Machine FAQ

Common questions about cap compatibility, vacuum sealing, jar sizes and production line integration.

What is the difference between a lug cap and a standard screw cap?

A metal lug cap engages with a compatible jar neck finish. Its lug structure, liner and jar finish must be checked together before selecting the capping equipment.

Does every lug cap capping machine create a vacuum?

No. A standard twist-off capper applies and tightens the lid. Vacuum sealing requires suitable equipment, packaging materials and a compatible mechanical or steam process.

Can one machine handle different jar and cap sizes?

Some machines support adjustments or change parts for different formats. The actual range depends on jar dimensions, cap design and the selected machine.

How can the finished seal be checked?

The inspection method depends on the product and closure. Relevant checks may include cap placement, closing torque, leakage and vacuum level.

Can lug cap capping be integrated into a complete line?

Yes. A suitable system can connect jar feeding, filling, cap feeding, capping, inspection, labeling and case packing.

What information is needed for a custom recommendation?

Provide your product details, jar and cap samples, filling process, target output, sealing requirements and available space.
