Engineered for high-speed throughput and uncompromising precision.
The transition from manual labor to high-frequency ultrasonic sealing and AI-integrated quality control.
In the modern manufacturing landscape, Wrapper Packing Machines have evolved from simple wrap-around tools to sophisticated "Smart Cell" systems. Today's global market demands machines that can handle multiple substrates—BOPP, PVC, and specialized laminates—at speeds exceeding 30,000 units per hour. Manufacturers are no longer just looking for hardware; they are seeking Information Gain through data-integrated machinery.
Technological bifurcation has led to two distinct routes: Heat Sealing, ideal for high-volume, cost-effective card packaging (8,000-12,000 pcs/hr), and Ultrasonic Sealing. The latter offers superior aesthetic finishes and hermetic seals without thermal degradation, reaching throughputs of 30,000 pcs/hr—a specialty of Wentong's R&D department.
As a Shenzhen-based leader, Wentong leverages the "Silicon Valley of Hardware." Our proximity to world-class sensor manufacturers, PLC suppliers (Siemens/Mitsubishi), and high-grade steel processors ensures a lead time that is 30% faster than European counterparts without compromising on the 5S standard or ISO certifications.
Where precision engineering meets AI-driven predictive maintenance.
Integration of servo-motor driven feeding systems with micro-millimeter precision. Wentong’s current line of step-by-step feeding die-cutting machines utilizes this to eliminate material waste.
Implementing CCD camera systems for "Single-mode visual positioning." This allows the machine to "see" print errors on the fly and adjust the cutting or wrapping path in real-time.
Predictive maintenance where the machine alerts the operator before a component fails. Cloud-based production monitoring for multi-factory synchronization.
High-security packaging for banking and telecommunications, requiring non-contact ultrasonic sealing to protect delicate chips.
Automated mounting and gluing for children's books, ensuring non-toxic adhesive application and durability for heavy use.
Transitioning from manual roll-handling to automated roll-to-sheet production for air and liquid filtration media.
Established in 2008, Wentong has over 20 years of experience in developing and manufacturing of smart card machines and post-press equipment. We have been committed to constantly growing and improving our products and service to meet all our customer’s requirements for production of children’s books, board books, paper cards and plastic cards.
Our wide range of products includes die cutting machine, card collating machine, card punching machine, SIM card production machine, board book mounting and gluing machine, automatic packaging machine, ultrasonic welding system, and more.
Located in the Guangming District of Shenzhen, China, our factory covers 5,000 square meters. The facility is meticulously divided into processing, assembly, and display areas, strictly adhering to 5S standards. This environment empowers our professional R&D team and assembly engineers to innovate high-quality solutions that balance price, performance, and durability.
Your success is built on our support infrastructure.
We provide video demonstrations and paper samples before contract signing. Our process ensures that the machine you receive is calibrated exactly to your substrate specifications.
One-year full warranty. We offer equipment installation, debugging, and comprehensive staff training. Consumables like belts and gluing rollers are always in stock for immediate dispatch.
Heat sealing uses thermal contact to melt the film, which is cost-effective for standard plastic cards. Ultrasonic sealing uses high-frequency vibrations to create a molecular bond, which is faster (up to 30k pcs/hr), creates a cleaner seal, and is safer for heat-sensitive electronics like SIM cards.
Our machines use PLC-controlled servo systems combined with visual positioning (CCD). This ensures that even if the print on the sheet is slightly offset, the cutting die adjusts its position to maintain accuracy within ±0.1mm.
Yes, Wentong specializes in customizable solutions. Our mounting and gluing machines are adjustable for various thickness and dimensions typical of children's "board books" and "learning cards."
We provide remote video guidance, dispatch engineers for on-site commissioning, and maintain a robust inventory of spare parts in Shenzhen for global air-express delivery.
