MLCC Casting M/C
High-speed ceramic film casting line with turret auto-splicing for non-stop continuous casting at both ends.
High-speed ceramic film (green sheet) production equipment that coats ceramic slurry onto release film (PET) and dries it with hot air. Turret and auto-splicing functions on the unwinder and rewinder keep the line running continuously and stably without stopping.

Configuration & detailed specifications
Turret Unwinder
Auto splicing changes bobbins without stopping. Left/right taper chucking with auto turret.
Infeed Part
The suction wrap angle achieves high tension, and an FFU (fan filter unit) supplies clean air. A static eliminator bar removes static from the incoming film.
Coater Part
Off-roll die coating. Lead roll tilting is controlled by 4-axis servos to compensate left/right thickness deviation. A VUV (vacuum + ultrasonic + vacuum) USC dry cleaner removes fine particles.
| USC head pressure | 15 ± 3 kPa |
|---|---|
| USC head vacuum | -0.5 ± 0.3 kPa |
| Effective cleaning distance | Max 600 mm |
| Nozzle gap | Manual 1.5 – 2.0 mm (TBD) |
Horizontal vs. Inclined Coating
Inclined coating is recommended for 10 or more chambers or when high tension is required — the larger suction roll wrap favors tension control. Horizontal coating is more stable with respect to slurry viscosity requirements.
Dry Chamber
Electric sheath heaters with hot-air circulation. Nozzles combine counter-flow (#1–3), touch-roll (#4–5) and slitter (#6–8) types. Optional waste-heat recovery saves energy.
Outfeed · CPC · EPC
The CPC prevents lateral drift right after the dryer, and the EPC aligns the final winding with edge deviation within 1 mm. Integrated thickness/defect detector + label printer.
Turret Rewinder
Non-stop winding with auto splicing. EPC edge deviation within 1 mm.
Clean Booth + Safety Clamp
Double clean booth at the coater and a clean booth at the exit winder. Magnetic safety clamps block doors from being forced open during operation.
Thickness Gauge + Defect Detector
Detects pinholes, thickness and defects in real time during casting to ensure quality. Measurement data logging supports process optimization and cost reduction.
