High-Speed Production & Micron Precision
The MLCC Ultra-Fast Tape Casting Machine is engineered for the next generation of capacitor manufacturing. By supporting casting speeds up to 120 m/min and maintaining a thickness range of 1–20 μm, it provides the high-throughput capabilities required for large-scale industrial lines. The precision thickness control (±3–5% accuracy) ensures that every dielectric layer is uniform, which is vital for the electrical performance and reliability of high-layer count MLCCs.
Advanced Web Handling & Tension Control
Stable material handling is guaranteed by a dual-shaft unwinding and rewinding configuration, supporting roll diameters up to φ500 mm and 250 kg load capacities. To prevent the stretching or cracking of ultra-thin ceramic green tapes, the system utilizes an active tension control loop that restricts fluctuations to within ±1.5% FS, ensuring the physical integrity of the material even at maximum speeds.
High-Efficiency Thermal Management
The drying system features air nozzles blowing from both the top and bottom of the chamber, reaching temperatures up to 120°C. This dual-sided airflow ensures even solvent evaporation and prevents skinning or warping. With drying lengths adjustable between 6 and 36 meters, the thermal profile can be finely tuned to match specific slurry formulations and carrier film speeds.
Safety and Static Elimination for Electronic Materials
Static electricity is a major risk in high-speed casting. Our system incorporates explosion-proof static elimination bars at critical stations (unwind, head, traction, and rewind) to protect the sensitive ceramic layers. Furthermore, the machine is CE-certified and equipped with emergency stop switches and a robust 280 kW power system featuring moisture-proof wiring for long-term operational safety.
Seamless Automation Integration
Designed with the "smart factory" in mind, this machine is fully compatible with downstream automation, including precision cutting, punching, and laminating systems. The integrated electrical architecture allows for real-time data monitoring and synchronization, making it the ideal centerpiece for a modern, automated MLCC production facility.

Frequently Asked Questions
How does the machine maintain accuracy at 120 m/min?
High-speed accuracy is achieved through a combination of high-precision casting heads, real-time laser thickness monitoring (optional), and ultra-stable tension control systems that eliminate vibration and web fluttering.
Is the drying system suitable for organic solvent slurries?
Yes. The drying chamber is equipped with an explosion-proof static removal system and specialized ventilation to safely handle organic solvents while maintaining high thermal efficiency up to 120°C.
Can the machine handle ultra-thin tapes below 5 μm?
Absolutely. The machine is specifically designed for the 1–20 μm range. The ±1.5% FS tension fluctuation control is critical for preventing the breakage of sub-5 μm tapes during high-speed handling.
Does the 280 kW power system require special installation?
The system is designed for industrial facility integration. It features moisture-proof wiring and advanced leakage protection to ensure longevity in manufacturing environments where chemical vapors or humidity may be present.
What is the modular drying length capacity of this system?
The drying section features a modular design customizable from 6 to 36 meters, utilizing air nozzles blowing from both top and bottom to ensure even solvent evaporation.
What safety certifications and static protections are included?
The machine is CE-certified, featuring emergency stop controls, 280 kW leakage protection, and explosion-proof static elimination bars positioned at the unwind, head, traction, and rewind stations.
