High-efficiency equipment designed for the next generation of SIM and ICC manufacturing.
Transforming Telecommunications Infrastructure through Advanced SIM Manufacturing
In the rapidly evolving landscape of global telecommunications, Custom SIM Making Machines have transitioned from simple mechanical punchers to high-precision integrated systems. As 5G penetration increases, the demand for SIM cards with higher memory capacity and embedded security features (eSIM/iSIM) is surging. Wentong Machinery is at the forefront of this shift, providing factories with modular solutions that can adapt to both traditional physical card production and modern embedded chip integration.
Our global commercial footprint spans from Southeast Asian tech hubs to European secure printing facilities, ensuring that our machinery meets the diverse localized needs of telecom operators and banking institutions. We don't just sell machines; we provide a roadmap for digital transformation in the card manufacturing sector.
Enabling seamless production for international telecom standards across Africa, Asia, and North America.
Integrated systems that ensure the physical integrity and data security of SIM card modules.
Optimized for 24/7 industrial operations with minimal downtime and maximum throughput (8000+ pcs/hour).
Energy-efficient motor systems and material waste reduction technologies built into every unit.
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 factory is located in Guangming District, Shenzhen, China. It covers an area of about 5,000 square meters. The workshop is divided into processing area, assembly area, machine display area and product display area. Strict implementation of the 5S standard allows employees to work in a safe and comfortable space.
Our commitment to R&D and the future of automated SIM production.
Focusing on high-speed card punching, magnetic stripe laying, and ultrasonic welding. Our current machines like the WT-011ZDCKJ represent the peak of mechanical-digital synergy, offering 0.01mm precision in card dimensions.
We are currently integrating AI-driven visual inspection systems that detect card defects in real-time. IoT connectivity allows factory managers to monitor machine health and production statistics remotely via mobile dashboards.
Transitioning toward full "Dark Factory" capabilities where SIM making machines operate autonomously, from raw material intake to final chip programming and laser engraving, fully integrated with global telecommunication security protocols.
How our custom SIM making machines serve specific regional markets.
Ideal for mass SIM card production for mobile network operators (MNOs) requiring high-volume daily output with zero-error rates in chip embedding.
Specially configured machines for EMV banking cards, ensuring strict adherence to Visa and Mastercard physical card standards.
Support for national ID card and driver's license production, integrating secure holographic overlays and tamper-proof die-cutting.
