PRODUCT FEATURES

1. High precision coating performance

·Roller system optimization design: using a combination of chrome plated steel rollers or silicon rubber rollers, the coating thickness can be controlled within a range of 5-200 μ m, with a uniformity error of ≤± 2%, and supports the preparation of nanoscale ultra-thin coatings.

·Multi mode coating: support forward coating, reverse coating, comma roll coating and other modes, and adapt to different viscosity materials such as solution, slurry, lotion (viscosity range 1-10000cP).

2. Intelligent process control

·Full process automation: equipped with PLC control system, supports custom coating parameters (such as roller speed, coating gap, slurry supply rate, etc.), can preset more than 15 sets of process programs, and automatically completes the substrate conveying, coating, drying (optional) and other processes after one click start.

·Precise temperature control system: The coating roller can be equipped with a heating/cooling module (temperature range: room temperature -150 ℃, accuracy ± 1 ℃), suitable for coating temperature sensitive materials (such as hot melt adhesive and thermosetting resin).

3. Flexible environment adaptation

·Wide width substrate compatibility: Standard coating width of 300mm, optional 500mm wide width machine, supporting roll (roll diameter ≤ 300mm) or sheet (* * size 500mm × 500mm) coating.

·Multi scenario scalability: Can be integrated into clean workshops (supporting * * 5 levels of cleanliness), or configured with local purification modules to meet high cleanliness coating requirements (such as microelectronics and medical fields).

4. Humanized design and safety guarantee

·Visual operation interface: equipped with a 7-inch color touch screen, real-time display of parameters such as roller speed, coating thickness, temperature, and remaining slurry amount, supporting historical data export (USB interface).

·Safety protection mechanism: equipped with roller overload protection, emergency stop button, slurry leakage monitoring * * and other functions to ensure the safety of operators.

·Maintenance convenience: The roller system adopts a quick detachable structure, and cleaning and replacing the rollers can be completed within 15 minutes. Combined with an automatic cleaning module (optional), it further improves efficiency.

5. Scalability and compatibility

·Optional upgrade module:

·Online detection component: can be equipped with beta ray thickness gauge and laser roughness gauge to monitor coating thickness and surface flatness in real time;

·Drying and curing system: Integrated infrared drying oven (temperature range: room temperature -200 ℃) or UV curing module to achieve coating drying integration;

·Automatic winding device: supports automatic tension control of the coil (tension range 5-50N), suitable for continuous coating process.
