High Precision Film Casting for MLCC Manufacturing
Our MLCC tape casting machine is engineered to produce ultra-thin, uniform ceramic layers with precise thickness control from 1-30μm (within 3-5% tolerance). With guide roller surface roughness ≤ Ra 0.8S and casting width accuracy ≤ ±1.5 mm, the system ensures smooth slurry spreading essential for high-density MLCC production. The ultrasonic web guiding system with swing roller correction provides exceptional film positioning accuracy, critical for consistent electrical properties in multilayer ceramic capacitors.
Advanced Heating and Drying Technology
The machine features a high-efficiency over-roll combined with suspended drying tunnel design for uniform, rapid tape drying. Six independent drying zones with PID temperature controllers and inverter-controlled airflow ensure precise thermal management. Bottom plate heating combined with hot air circulation creates uniform temperature distribution, while the modular design allows easy extension of drying chamber length to accommodate different production requirements and material formulations.
Variable Thickness Control for Diverse Applications
With precise control over film thickness ranging from 1-30μm, this tape caster supports production of various MLCC types with specific electrical properties and capacitance values. This versatility allows manufacturers to tailor ceramic tapes for different industry applications, from consumer electronics to automotive and industrial systems. The consistent thickness control is crucial for achieving reliable performance in compact, high-capacitance components.
Smooth Surface Quality and Defect Prevention
The tape casting process produces ceramic films with exceptionally smooth surfaces and minimal defects such as air bubbles, uneven texture, or irregularities. This surface quality is essential for achieving high-quality multilayer ceramic substrates that deliver optimal electrical and mechanical performance. The automated slurry spreading and tension control systems work together to eliminate common manufacturing defects that could impair component reliability.
Automated Process Control and Monitoring
Advanced automation systems control critical parameters including casting speed, slurry viscosity, and substrate tension, ensuring consistent production with minimal human intervention. Real-time monitoring systems track all process variables, providing immediate feedback and maintaining optimal operating conditions. This level of automation reduces errors, improves production efficiency, and ensures consistent quality across extended production runs.

Frequently Asked Questions
What is tape casting in ceramics?
Tape casting is a manufacturing process that produces thin, flat ceramic sheets by spreading slurry onto a moving carrier. The solvent evaporates in controlled drying chambers, leaving flexible green tape that can be cut, stacked, and fired to create multilayer electronic components like MLCCs.
What tape to use for ceramics?
For ceramic tape casting, specialized carrier films (typically PET or silicone-coated papers) are used to support the ceramic slurry. These tapes must have appropriate surface properties to ensure smooth release and uniform thickness during the casting and drying processes.
What is ceramic casting?
Ceramic casting refers to various forming techniques that shape ceramic materials, including tape casting (thin sheets), slip casting (complex 3D shapes), and investment casting. Each method produces different ceramic forms for specific electronic and industrial applications.
What is the difference between slip casting and tape casting?
Slip casting uses porous molds to create 3D ceramic shapes through capillary action, while tape casting spreads slurry on flat surfaces to produce uniform thin sheets. Tape casting is ideal for flat multilayer components like MLCCs, whereas slip casting suits complex-shaped ceramics.
What is the film thickness range of this MLCC tape casting machine?
This precision tape casting machine supports a film thickness range of 1-30 μm within a 3-5% tolerance, making it suitable for high-density MLCC manufacturing with highly consistent electrical properties.
What safety and monitoring systems does the equipment include?
The system is equipped with Japan RIKEN combustible gas detectors for continuous solvent concentration monitoring with automatic alarms/shutdown, explosion-proof motors in the oven zones, and optional inline thickness measurement offering real-time 2D/3D coating maps.
