What This Capping Machine Page Helps You Decide
Most buyers do not only search for a machine model. They are trying to solve a packaging line problem: cap tightening, leakage, bottle stability, line connection or automation upgrade. This page helps you compare automatic capping machine options before requesting a quotation.
Which Capping Machine Fits My Cap?
Compare standard screw capping, angle-adjustable capping, servo lifting and claw-type servo capping according to your bottle and closure design.
How to Avoid Loose or Tilted Caps?
Understand how torque control, bottle gripping, cap alignment, guide rails and conveyor speed affect final capping quality.
Can It Connect with My Filling Line?
Plan the capping machine together with filling, sealing, labeling, coding and conveyor systems instead of treating it as a separate unit.
What Should I Send for Pricing?
Prepare bottle photos, cap photos, cap diameter, bottle height, target output and line layout so the capping machine supplier can quote accurately.
Choose the Right Capping Machine by Production Requirement
Instead of choosing by model number first, start from your bottle, cap and line requirement. This helps avoid loose caps, over-tightening, bottle shaking and unstable line connection.
Capping Machine Selection by Cap Type
Different closures need different capping methods. A screw cap capping machine, pump cap capping machine or trigger sprayer capping solution should be matched according to real samples, not only cap diameter.
Screw Caps
Suitable for standard bottle caps used in cosmetics, food, chemical, detergent and daily-use products. Four-wheel capping is commonly used for continuous production.
Pump Caps
Pump caps may require sample testing because the tube length, pump head direction and bottle stability can affect cap placement and tightening.
Flip-Top Caps
Flip-top caps need careful bottle positioning and stable cap alignment. The machine should avoid crooked caps and unstable tightening.
Trigger Sprayers
Trigger sprayers and special closures often need customized handling. Photos, drawings or samples are recommended before quotation.
Other Special Caps or Bottle Types?
If your cap type is not listed here, such as irregular closures, special bottle mouths, custom pump heads or non-standard cap structures, send us bottle and cap photos. LEKA can check the sample and recommend a customized capping machine solution.
Standard Capping Machine or Servo Capping Machine?
LEKA capping machines can be grouped into two main directions: standard capping machines for common screw cap applications, and servo capping machines for higher control, lifting adjustment or special cap handling.
Standard Capping Machine Series
Suitable for common screw cap bottles, daily chemical bottles, food bottles and general packaging line use.
This series focuses on stable bottle gripping, four-wheel capping and practical line connection. It is suitable when the cap structure is standard and the main requirement is reliable continuous capping.
Servo Capping Machine Series
Suitable for projects requiring servo lifting, claw-type capping, better control or enclosed protection.
This series is more suitable when the bottle height, cap structure or production environment needs stronger control. It can support servo-controlled lifting adjustment and claw-type servo capping according to the model.
Standard Capping Machine Model Options
The standard series is suitable for many screw cap bottle applications. It focuses on practical capping stability, bottle conveyance and integration with packaging lines.

What Affects Automatic Capping Machine Selection?
A reliable automatic capping machine is selected by packaging conditions, not only machine price. These factors help determine whether a standard capping machine, servo capping machine or customized capping solution is required.
Common Problems When Choosing a Bottle Capping Machine
Capping problems are often caused by the wrong match between cap type, bottle shape, torque setting, guide rail design and line speed.
Loose Caps and Leakage
If the cap is not tightened enough, the bottle may leak during transport, storage or carton packing.
Over-Tightened Caps
Excessive torque may damage bottle threads, deform the bottle neck or make the cap difficult to open.
Tilted or Misaligned Caps
If cap placement is unstable before tightening, crooked caps and rejected bottles may occur.
Bottle Shaking During Capping
Tall, slim or lightweight bottles may require better side guides, belt gripping or bottle holding design.
Wrong Model for Bottle Shape
Straight-mouth and slanted-mouth bottles may require different machine adjustment directions.
Unmatched Line Speed
If filling, capping, sealing and labeling speeds are not matched, the production line may stop or accumulate bottles.

More Than a Capping Machine Model List
A capping machine selection page should help buyers judge model fit, supplier capability, technical communication and after-sales support. This section brings the factory background, engineer review, certificates and service process together so customers can understand LEKA before sending an inquiry.
Factory-Based Packaging Machine Support
LEKA Pack Line works with buyers who need bottle filling, capping, sealing, labeling, coding and line coordination. For capping projects, this matters because cap tightening is affected by bottle shape, cap structure, conveyor layout and upstream filling speed.
Instead of treating the bottle capping machine as an isolated unit, LEKA reviews the bottle, cap, production output and line layout together before recommending LEKAXG standard or servo series models.
Reviewed from a Practical Machine Selection Perspective
This page is reviewed from the perspective of real capping machine selection: cap type, bottle stability, torque adjustment, conveyor connection, filling line speed and after-sales communication.
From Sample Review to Pre-Shipment Capping Test
For a bottle capping machine project, the real sample is more useful than only a written specification. LEKA can review bottle and cap samples, check the capping method, and confirm whether standard four-wheel capping, servo lifting or claw-type capping is more suitable.
For complete filling and capping line projects, we recommend line testing before shipment. This allows customers to check bottle feeding, filling, capping, sealing, labeling and conveyor flow before delivery.

Capping Machine FAQ
Common questions from buyers who are comparing automatic capping machines for bottle packaging lines.
Which LEKA capping machine model should I choose?
If your bottle uses a standard screw cap, LEKAXG-A or LEKAXG-C may be suitable. If your bottle has a slanted mouth or requires angle adjustment, LEKAXG-B is more relevant. If you need servo lifting adjustment or claw-type capping, consider LEKAXG-SF-A, LEKAXG-SF-B or LEKAXG-SF-C.
What is the difference between standard and servo capping machines?
Standard capping machines are suitable for many common screw cap applications. Servo capping machines are more suitable when the project requires servo-controlled lifting adjustment, claw-type locking, cleaner enclosed protection or more controlled setup.
Can the capping machine connect with a filling machine?
Yes. The capping machine can be connected with filling, sealing, labeling, coding and conveyor systems. For complete line projects, the machine speed and bottle flow should be matched across all equipment.
Can one capping machine handle different bottle sizes?
It depends on the size range, cap diameter, bottle shape and required adjustment method. Some projects can be handled through machine adjustment or change parts, but real bottle and cap samples should be checked first.
What information is needed for quotation?
Please provide bottle photos, cap photos, cap diameter, bottle size, product type, required output and whether you need filling, sealing, labeling or coding equipment together.
Is a servo capping machine always better than a standard capping machine?
Not always. A servo capping machine is useful when the project needs servo lifting, claw-type capping, better adjustment control or enclosed protection. For many standard screw cap bottles, a standard four-wheel capping machine may be more practical and cost-effective.
