In the rapidly evolving telecommunications landscape, the demand for precision-engineered SIM card making machines has shifted from simple mechanical punching to high-speed, multi-functional automated systems. As global connectivity expands toward 5G and IoT integration, Wentong Machinery Co., Ltd. stands at the forefront of this technological revolution. Established in 2008 with over 20 years of technical heritage, our focus remains on providing "Information Gain"—the competitive edge that allows our clients to achieve sub-micron precision and unmatched throughput.
Our roadmap emphasizes the integration of Smart Card Lines with "Cyber-Physical Systems," ensuring that every machine we supply is not just a tool, but a data-generating asset capable of predictive maintenance and real-time efficiency monitoring.
Located in the heart of the Guangming District, Shenzhen, our 5,000-square-meter facility is a beacon of modern engineering. We implement strict 5S standards across processing, assembly, and testing zones to ensure absolute reliability.
Unlike standard suppliers, Wentong integrates invention patents and utility model patents directly into our production lines. Our team of skilled electricians, fitters, and R&D engineers work in synergy to customize solutions for complex card geometries.
Operating across Southeast Asia, Europe, Africa, and North America, we provide a robust supply chain that mitigates geopolitical risks through localized support and rapid-response spare parts inventory.

Global card manufacturers face a dual challenge: increasing production speed while maintaining the structural integrity of the SIM card's delicate IC chip. Our holistic solutions address these through specialized equipment:
Our automatic magnetic stripe laying machines and tape laying systems ensure high-adhesion precision, critical for financial-grade SIM cards and hybrid multi-function cards.
From commercial industrial die-cutting to book inner page precision, our machinery handles diverse substrates—including paper, plastic, and multi-layered composites—with zero deformation.
Incorporating 20kHz+ ultrasonic welding, our automated packaging lines achieve hermetic seals that protect internal circuitry from environmental degradation, ensuring a 10-year operational life for the end product.
Navigating international standards (ISO/IEC 7810, 7816) is paramount. Wentong provides comprehensive support to ensure your facility meets local regulatory and quality benchmarks. We offer equipment installation, debugging, and training services globally.
Our high-speed automated packaging lines, equipped with ultrasonic sealing, can achieve up to 30,000pcs/hour, depending on the material and card size.
We use high-grade alloy steel dies and servo-driven feeding systems that ensure a tolerance within ±0.05mm, meeting the strict requirements of modern mobile devices.
Yes, our equipment is designed with adjustable pressure and temperature controls, allowing seamless switching between PVC, ABS, PET, and eco-friendly paper-based cards.
We provide remote technical diagnostics via video, dispatch local engineers for complex setups, and maintain a 12-month full-service warranty for all new installations.
