In apparel RFID traceability and smart card manufacturing, large cards often need several RFID labels or anti-counterfeiting pressure-sensitive labels applied. Conventional single-head equipment hits a capacity bottleneck on such multi-area work, and multiple passes cause alignment deviation. Breaking through the efficiency problem of simultaneous multi-label application on large cards is a focus for many printing and card processing plants.

A multi-head synchronous approach breaks the large-card labeling bottleneck

For simultaneous multi-label application on the flat faces of large-format cards, multi-head parallel operation has gradually become the industry consensus. When a conventional automatic labeling machine handles cards hundreds of millimeters long and wide with a single head applying labels in sequence, the material path is long and the relative position accuracy between labels is hard to guarantee. Wanzhi Automation therefore developed the WZ-125G automatic four-head card labeling machine. Designed for RFID-embedded hang tags and large cards, it applies labels to several areas of a card in one pass using multiple heads working in sync, eliminating several line steps, greatly saving floor space and equipment investment, and providing an efficient pressure-sensitive labeling solution for high-volume card production.

WZ-125G core specifications and architecture

Technically, the WZ-125G’s core is its high-accuracy, high-stability hardware architecture. It uses high-accuracy two-way supported labeling modules with a one-piece, long, heavy-duty stainless steel frame, and the machine weighs 900Kg. This heavy design suppresses offset and vibration during high-speed material travel and holds positioning accuracy at ±0.5mm, meeting strict quality control requirements. On capacity, maximum label dispensing speed reaches 60M/min and overall throughput is about 1,200~1,600 cards/minute (varying with label spacing). The machine also handles a wide range of card sizes: large cards 300mm to 600mm in length and width work without frequent machine changes. Standard automatic sheet feeding and rear automatic stacking and receiving mechanisms enable continuous production with no manual intervention.

Practical selection points and industry application advice

In selection and application, companies should plan sensibly around the characteristics of their orders. For apparel RFID hang tags, access control cards and furniture hang tags, we suggest focusing on the following points:

  • Modular configuration: the number of labeling heads can be increased or reduced flexibly, and machines with 2 to 6 heads can be custom-built to the card label layout, giving high equipment reuse.
  • Ease of operation: an independent industrial touch-screen control panel supports independent adjustment of each head’s parameters and program storage, so changeover between card models is easy.

The Wanzhi technical team advises companies introducing this kind of labeling machine to evaluate card size, label count and expected throughput together in order to match the right multi-head parallel solution.

FAQ

How is multi-head alignment accuracy ensured when labeling large cards?

The machine uses high-accuracy two-way supported labeling modules and a 900Kg heavy-duty frame, which effectively reduces vibration at high speed and keeps positioning accuracy at ±0.5mm when several heads work in sync.

What affects the machine’s actual throughput?

Overall throughput varies between about 1,200 and 1,600 cards/minute, depending mainly on the label spacing and the actual card size; the smaller the label spacing, the more cards pass per unit time.

If order demand grows later, can the number of heads be upgraded?

Yes. The machine uses a modular head design supporting flexible addition or removal of 2 to 6 head groups, so companies can add heads as needed for later multi-category card orders to raise throughput.
