Product Description

HU3020 Bottle Cap Laser Coding Machine for High-Speed Variable Coding and Traceability

Modern bottle cap production is no longer limited to printing a simple date, batch number or fixed production code. Beverage, dairy, food, alcoholic beverage and personal care manufacturers increasingly need every bottle cap to carry clear, permanent and sometimes unique information that can support production traceability, product identification, anti-counterfeiting and consumer marketing.

This change creates a more demanding production requirement. A Bottle Cap Laser Coding Machine must do more than simply create a visible mark on plastic. It must operate continuously with the cap feeding system, maintain stable coding quality at production-line speed, process changing data, verify the finished code and prevent incorrectly coded caps from entering the qualified product flow.

The HU3020 is designed around this complete production requirement. Instead of functioning as a standalone UV Laser Coding Machine, the HU3020 combines automatic cap feeding, vacuum conveying, position tracking, 355 nm UV laser coding, online vision inspection, automatic NG rejection and data communication into an integrated Bottle Cap Laser Coding System.

This enables manufacturers to move from an individual laser marking process toward a complete automated coding and traceability workflow.

Cap Feeding → Vacuum Conveying → Position Tracking → UV Laser Coding → Vision Inspection → NG Rejection → Data Traceability

The complete process is designed to keep bottle caps moving continuously while coding, inspection and quality control are completed automatically.

Automated Production Solution

Operational Process

01. Automatic Cap Feeding
A waterfall-type cap sorter continuously feeds caps into the Bottle Cap Laser Coding Machine, supporting up to 1800 BPM.

02. Vacuum Conveying
A 1750 × 70 mm vacuum conveyor stabilizes caps for consistent coding and inspection.

03. Position Tracking
Omron position tracking synchronizes cap movement with the laser trigger, enabling continuous flying marking without stopping each cap individually.

04. 355 nm UV Laser Coding
The 20W 355 nm UV laser supports Variable Data Laser Coding, including QR codes, Data Matrix and serial numbers. 

05. Online Vision Inspection
100% Online Vision Inspection verifies and decodes each marked cap. 

06. Automatic NG Rejection
The Panasonic PLC triggers air-blow rejection to remove defective caps automatically.

07. Data Traceability
USB and TCP/IP support data communication and Bottle Cap Traceability System integration.

8.Production Note
Actual continuous throughput depends on cap material, color, code content, vision criteria and final commissioning.

Advantages of HU3020

How to Ensure Every Code Is Reliable and Valid

Laser coding is only the first step in bottle cap identification. In high-speed production, manufacturers need to ensure that every code is correctly marked, readable and qualified before the product moves to the next process.

The HU3020 Bottle Cap Laser Coding System integrates an industrial Vision Inspection System after the UV laser coding process to verify each marking result in real time. Equipped with a Hikvision industrial color camera, Computar industrial lens and controlled lighting system, the system can inspect and decode QR codes, Data Matrix codes, characters and other variable information after QR Code Laser Marking.

Through 100% Online Vision Inspection, the system identifies missing codes, unclear markings or unreadable information automatically. When an abnormal result is detected, the Panasonic PLC controls the solenoid valve air-blow mechanism to remove the defective bottle cap from the production flow.

This creates a complete quality-control process:Laser Coding → Vision Inspection → Result Judgment → Automatic NG Rejection

By combining coding, inspection and rejection in one automated process, HU3020 helps manufacturers maintain stable production quality and provides reliable data support for future Bottle Cap Traceability System integration.

Application

Bottle Cap Coding Applications Across Multiple Industries

The HU3020 Bottle Cap Laser Coding Machine is designed for plastic bottle caps used in beverage, bottled water, dairy, alcoholic beverage and personal care production. With Plastic Bottle Cap Laser Coding, manufacturers can apply permanent characters, batch numbers, serial numbers, QR codes, Data Matrix codes and other variable information to different cap colors and application scenarios.

Typical applications include production traceability, anti-counterfeiting, anti-diversion and promotional coding. For inside-cap applications, QR Code Laser Marking can also support consumer campaigns while reducing the risk of codes being scanned before purchase.

Because cap materials, pigments, cavity structures and coding positions vary between products, HND LASER recommends testing actual customer samples before finalizing the UV Laser Coding Machine parameters and production-line configuration.
