Labels shifting when applying several labels to smart cards and RFID hang tags? The three-head parallel labeling solution explained

Labels shifting when applying several labels to smart cards and RFID hang tags? The three-head parallel labeling solution explained

In the garment RFID traceability and smart card manufacturing industries, large cards often need several RFID labels or information labels applied to the same surface. Conventional single-head labelers struggle with poor registration accuracy and limited throughput when applying multiple labels at the same time. Achieving efficient, accurate RFID labeling is therefore a key concern for many printing and card manufacturing companies.

Industry pain points in simultaneous multi-label application

Large cards (for example 300-600mm in length and width) can shift slightly during high-speed conveying because of machine vibration or material inertia. Applying different labels at several inline stations not only adds equipment and floor space but also accumulates positioning error, which leads to wrinkled or misaligned labels. The three-head parallel labeling solution applies several labels in a single pass, physically reducing process steps and effectively solving the industry-wide problem of poor multi-label registration.

The WZ-125F three-head parallel labeling solution

To meet this demand, Wanzhi Automation developed the WZ-125F automatic three-head card labeling machine. The machine uses high-accuracy two-side supported labeling heads together with an extended one-piece stainless steel frame; at 800Kg, it keeps conveying stable at high speed and holds labeling registration within ±0.5mm. For output, the label dispensing speed reaches 60M/min and overall capacity is about 1000-1400 cards/min. The machine also comes standard with automatic sheet feeding and separating plus a downstream automatic stacking and collecting mechanism, so a full stack of cards is loaded in one go and the line runs with minimal manual intervention, greatly improving continuous operation on RFID labeling lines.

Practical tips and selection criteria

In practice, the configuration should follow the label layout process for each card. The labeling heads on the WZ-125F use a modular design and can be specified with 2 to 6 heads, so one machine covers several card products. For small and medium card printers, we recommend choosing three or four heads according to the label count in day-to-day orders, and making full use of the independent touch screen industrial PC to adjust parameters separately, which allows fast program switching and one-touch storage and shortens changeover time.

FAQ

How is vibration avoided when labeling large cards at high speed?

The extended one-piece stainless steel frame brings machine weight to 800Kg and, together with the high-accuracy two-side supported labeling heads, absorbs vibration during high-speed operation and keeps labeling stable.

How can programs be switched quickly between products when applying multiple labels?

The machine is equipped with an independent touch screen industrial PC, each head’s parameters can be adjusted separately, and programs can be stored and recalled with one touch, so changeover between products is quick and simple.

Can the labeling heads be upgraded later if capacity requirements increase?

Yes. The WZ-125F uses a modular head design, so heads can be added or removed later as order volumes change; 2 to 6 heads can be specified, giving one machine multiple uses.
