Automatic Vacuum Twist-Off Jar Capping Machine
The ZONESUN ZS-XG240 is an automatic vacuum capping machine for compatible glass jars with twist-off caps measuring 38–82 mm in diameter. It combines mechanical vacuum extraction with adjustable constant-torque capping, at a speed of up to 40 bottles/min.
The physical vacuum chamber extracts air without steam injection. The machine supports suitable hot-fill and cold-fill packaging workflows and can be planned between filling and labeling stations.

Machine Details
PLC Touchscreen Control
Multilingual controls provide access to operating settings and monitoring of speed and vacuum levels, with interlocking safety protection.
Vacuum Capping Head
Adjustable constant-torque capping and slip protection help control cap tightening.
Mechanical Vacuum System
Extracts air mechanically rather than using steam injection.
Physical Vacuum Chamber
Provides the enclosed vacuum environment used during jar closing.
Key Features and Benefits
- Mechanical vacuum extraction: creates the vacuum environment without introducing steam.
- Controlled cap tightening: adjustable constant torque supports consistent closing for the configured lid.
- 38–82 mm cap range: accommodates compatible twist-off lid formats with suitable tooling.
- Hot- and cold-fill workflows: supports configuration around the required filling process.
- PLC operation: combines parameter settings and operating monitoring through the touchscreen.
- Line integration: can be arranged with upstream filling and downstream labeling equipment.
How Vacuum Jar Capping Works
- Present the filled jar: supply the jar and lid according to the configured handling arrangement.
- Position the jar: bring it into the capping station.
- Extract air: the mechanical system establishes vacuum in the chamber.
- Tighten the lid: the capping head closes the compatible twist-off cap at the selected torque.
- Discharge: transfer the closed jar to subsequent handling or labeling.
How to Select Your Jar Capping Setup
- Jar: glass container dimensions, neck finish and sample photos or drawings.
- Cap: diameter, lug design, liner and supplier closing specifications.
- Product: contents, fill temperature and headspace.
- Closing requirements: target vacuum, torque and seal inspection criteria.
- Production line: required output, conveyor arrangement and available voltage.
Frequently Asked Questions
What is the ZS-XG240 used for?
It vacuum-caps compatible glass jars using twist-off lids, combining mechanical air extraction and controlled cap tightening.
Does it use steam injection?
No. The listed system uses mechanical vacuum extraction and a physical vacuum chamber.
What cap sizes does it support?
The specified cap diameter range is 38–82 mm.
What is the capping speed?
The listed speed is up to 40 bottles/min.
Can it be used after hot or cold filling?
Both workflows are listed applications. Match the jar, lid liner, fill temperature and closing requirements to the planned setup.
Does vacuum capping replace product preservation processing?
Vacuum capping is a packaging step. Product preservation and shelf-life validation require the appropriate product-specific process; the capper alone does not establish these results.
Does it include the optional tracking press capper?
The tracking press capping machine is a separate optional purchase. It should be specified separately when required.
What should I send for a quotation?
Send jar and lid samples or drawings, the product and fill temperature, target vacuum and required output through the chat window.
