Introduction: throughput and accuracy challenges in multi-label labeling of large cards
As RFID traceability in apparel and smart access cards become more common, demand is growing for applying multiple labels to large flat cards. Conventional single-head labeling, however, struggles to meet mass-production requirements, while multi-station transfer adds cost and defect rates. When selecting a labeling machine, balancing throughput and accuracy for simultaneous multi-label application has become a challenge for many manufacturers.
Problem analysis: process challenges and solutions for large-card labeling
Large cards, such as RFID hang tags measuring 300~600mm in length and width, often suffer from labeling misalignment caused by material wobble during multi-label application, as well as frequent manual loading and unloading. Multi-head synchronous parallel labeling was developed to address these issues: it applies labels at several positions in a single pass, greatly reducing line steps. For such process challenges, Wanzhi Automation developed a modular multi-head synchronous high-speed labeling solution that integrates automatic sheet feeding, parallel multi-head labeling, and automatic collection, providing an efficient automation path for batch card processing.
Technical analysis: advantages of the WZ-125F automatic three-head card labeling machine
Take the WZ-125F automatic three-head card labeling machine as an example; it demonstrates solid technical performance in RFID labeling. First is the balance between throughput and accuracy: maximum label dispensing speed reaches 60M/min with throughput of about 1000-1400 cards/min. The elongated one-piece stainless steel frame, with a dead weight of 800Kg, works with high-precision dual-side-supported labeling heads to suppress vibration during high-speed conveying and keep labeling positioning accuracy stable at ±0.5mm. Second is a high degree of automation and flexibility: automatic material separation and loading plus a rear automatic stacking collection mechanism allow a full stack of cards to be loaded at once for unattended operation. In addition, the labeling heads use a modular design, with 3 heads standard and 2~6 heads available as an option, so companies can adjust capacity dynamically to order demand.
Selection considerations: choosing the right machine for a large-card line
When selecting a labeling machine of this type, the Wanzhi Automation technical team recommends that companies focus on three areas. First, throughput and scalability: assess current order volumes and future growth, and choose a machine with modular head expansion. Second, running stability: labeling large cards places high demands on frame rigidity and head support structure, so examine machine weight and guide design. Third, loading and unloading integration: choose a model with automatic sheet feeding and stacking collection to reduce manual intervention costs. This solution is widely used in apparel RFID traceability, smart card manufacturing, and paper printing and converting.
FAQ
Can the number of labeling heads on the WZ-125F be increased later?
Yes. The machine uses a modular head design with 3 labeling heads standard, and up to 6 heads can be added later as required by the card label layout process and throughput needs.
How is ±0.5mm accuracy maintained when labeling large cards at high speed?
The machine uses an elongated one-piece stainless steel frame with a dead weight of 800Kg and high-precision dual-side-supported labeling heads, effectively reducing frame vibration and drift during high-speed material travel and thereby safeguarding labeling accuracy.
Is setup complicated when switching between card specifications?
No. The machine has an independent touch-screen industrial control panel, parameters for each head group can be adjusted independently, and programs can be stored with one touch. When switching products, simply recall the corresponding program; setup is quick and simple.
