The equipment requires a 3-phase 380 V / 50 Hz power supply and compressed air at 0.5-0.7 MPa for safe operation. The drying oven operates at temperatures up to 120°C, necessitating proper ventilation and thermal management.
- Power and Air Supply Requirements: The machine requires a 3-phase 380 V / 50 Hz power supply and compressed air at 0.5-0.7 MPa for safe operation.
- Drying Oven Thermal Limits: The drying oven operates at temperatures up to 120°C, requiring adequate ventilation and thermal management to prevent overheating.
- Coating Thickness Control: Coating thickness is adjustable from 40 to 200 μm with a precision of ±3 μm, requiring careful micrometer adjustment to maintain uniformity.
- Substrate Tension and Alignment: Substrate tension is adjustable up to 60 N with a rewinding accuracy of ±0.5 mm, necessitating precise tension control to avoid web distortion.
This procedure outlines the safe and effective operation of the coating machine, from setup to coating. It covers essential steps for achieving consistent coating results.
Required Equipment: PLC touch screen control panel, Micrometer adjustment mechanism, Compressed air supply (0.5-0.7 MPa)
- Verify utilities
Verify that the 3-phase 380 V / 50 Hz power supply and compressed air at 0.5-0.7 MPa are connected and stable. - Set coating parameters
Set the desired coating mode (continuous or intermittent) and coating thickness (40-200 μm) using the PLC touch screen. - Thread substrate
Thread the substrate through the guide rollers, ensuring proper tension and alignment with the deviation correction device. - Adjust drying temperature
Adjust the drying oven temperature to the required level (up to 120°C) and allow it to stabilize. - Start coating process
Start the coating process and monitor the coating thickness and web tension, making fine adjustments as needed. - Monitor drying and rewinding
Monitor the drying section and rewinding accuracy, ensuring the substrate remains aligned and the coating is uniform.
What is the coating thickness range and accuracy of the Atomfair-TC309 Tri-roll Transfer Coating Machine?
The Atomfair-TC309 supports a slurry-dependent coating thickness of 40 to 200 μm with a coating accuracy of ±3 μm (edge error ±5 μm). Thickness is adjusted via stepless manual adjustment with a micrometer display precision of 1 μm, enabling precise metering for lab and pilot coating processes.
Can the Atomfair-TC309 handle both continuous and intermittent coating, and what are the implications for substrate tension control?
Yes, the Atomfair-TC309 supports both continuous and intermittent coating modes with a maximum mechanical speed of 5 m/min. It features substrate tension control up to 60 N (adjustable) and a deviation correction device to ensure stable tape running, which is critical for maintaining coating uniformity during mode transitions and intermittent operation.
What are the utility and infrastructure requirements for installing the Atomfair-TC309?
The Atomfair-TC309 requires a 3-phase 380 V / 50 Hz power supply with a maximum power consumption of 30 kW, and compressed air at 0.5 to 0.7 MPa. The oven length is 4.5 m (3 sections × 1.5 m, customizable) with drying temperatures adjustable from room temperature to 120 °C, and the overall machine footprint is L6600 × W1200 × H1600 mm with a net weight of approximately 2 tons.
The Atomfair-TC309 tri-roll transfer coating machine delivers ±3 μm coating accuracy with a 40–200 μm wet thickness window, dual-mode continuous/intermittent operation, and a 4.5 m three-zone hot-air oven, making it a versatile pilot-scale tool for slurry-based web coating. Its 330 mm guide roll width and 5 m/min max speed suit R&D and small-batch production, though the 30 kW power draw and 0.5–0.7 MPa compressed air requirement demand dedicated lab infrastructure.
Positive
- High coating accuracy with precision metering: Comma knife metering with a 1 μm micrometer display achieves ±3 μm coating accuracy (edge ±5 μm), enabling reproducible thin-film deposition for electrode or functional layer applications.
- Dual-mode operation with tension control: Freely switchable continuous and intermittent coating modes, combined with substrate tension control up to 60 N and a deviation correction device, ensure stable tape running and precise pattern registration during pilot runs.
Trade-offs
- Requires compressed air and high power supply: The machine needs a 0.5–0.7 MPa compressed air supply and a 3-phase 380 V / 50 Hz connection drawing up to 30 kW, which may not be available in standard lab settings without dedicated utilities.
- Coating thickness is slurry-dependent: Achievable wet coating thickness is limited to 40–200 μm and varies with slurry rheology, so users must validate process parameters for each new formulation to maintain the stated accuracy.
