High-Temperature Infrared Drying Lab Coating Machine

Infrared Drying Coating Machine for High-Temperature Film Research - TOB-RVCH-300

Product Overview and Ideal Applications

The TOB-RVCH-300 is an infrared drying coating machine for high-temperature film research. It is widely used in various kinds of high-temperature coating research - ceramic films, crystal films, battery material films, and special nano films - and it is designed to adapt to the future development of science and technology for film formation under high-temperature conditions.

The machine coats in the flat-plate mode with a standard film applicator: the applicator is driven by a motor across the substrate, so the coating speed is stable and adjustable. The coating stroke (300 mm) and the coating speed (0-120 mm/s) are set steplessly in the touch screen, the coating thickness is adjusted within the 0-6 mm range, and the coating accuracy is ±3 µm - with an optional 1 µm dial indicator for finer thickness reading.

The substrate is held on a vacuum aluminum plate (L365 mm x W200 mm x H23 mm). Copper foil, aluminum foil, and similar substrates can be placed or removed quickly, and the substrate is adsorbed without deformation. Vacuum is provided by the built-in oil-free vacuum pump (1 unit) or by connecting the machine to an external vacuum source.

After coating, the film is dried in the same machine by infrared heating. Large-area infrared heating ensures high-precision uniform temperature in the chamber, and the heating and drying system covers room temperature to 130 °C with a digital display temperature controller and an accuracy of ±1 °C. Because the machine is compact - L560 mm x W420 mm x H370 mm, 50 kg - it can also be used inside a glovebox, for research on films that must be handled in a controlled atmosphere. All parameters are set conveniently through the PLC and touch screen control.

Ideal for:

• High-temperature coating research - ceramic films, crystal films, battery material films, and special nano films.
• Laboratories that coat and dry in one compact machine, with infrared drying across room temperature to 130 °C.
• Research performed inside a glovebox, where the machine's small dimensions and convenient operation save space.
• Processes that coat copper foil, aluminum foil, and similar substrates held flat on a vacuum aluminum plate without deformation.
• Experimental work that requires stable, motor-driven coating with the stroke and coating speed set steplessly on the touch screen.

Where the Coater Fits in High-Temperature Film Research

In high-temperature film research, coating and drying form one sequence: the film-forming material is prepared as a slurry or dispersion, coated onto a substrate at a controlled thickness, and dried to form the film. Both the substrate and the drying conditions influence the resulting film, so equipment that performs coating and drying on one machine - with each parameter set accurately - helps keep experiments comparable.

The TOB-RVCH-300 performs this sequence on a single machine:

1. Substrate placement: the substrate - copper foil, aluminum foil, or another film substrate - is placed on the vacuum aluminum plate and held flat by vacuum, supplied by the built-in oil-free vacuum pump or an external vacuum source. The substrate is adsorbed without deformation.
2. Parameter setting: the coating stroke (300 mm, stepless) and the coating speed (0-120 mm/s, stepless) are set in the touch screen, and the required coating thickness is set on the standard film applicator within the 0-6 mm adjustable range.
3. Coating: the applicator is driven by the motor along the stroke at the set speed, coating the substrate in the flat-plate mode.
4. Drying: the infrared heating system dries the film in the chamber, from room temperature up to 130 °C, with the temperature set on the digital display temperature controller (±1 °C accuracy). Large-area infrared heating keeps the chamber temperature uniform.
5. Removal and evaluation: the coated and dried film is taken off the vacuum plate for characterization or the next process step.

For films that are sensitive to air or moisture, the machine can be operated inside a glovebox, so the same coating and drying sequence can be carried out in a controlled atmosphere.

Key Engineering Characteristics of the TOB-RVCH-300

1. Large-Area Infrared Heating with High-Precision Uniform Temperature: The machine adopts large-area infrared heating, ensuring high-precision uniform temperature in the chamber. The heating and drying system covers room temperature to 130 °C with a digital display temperature controller and an accuracy of ±1 °C.
2. Flat-Plate Coating with a Motor-Driven Applicator: The machine uses the flat-plate coating mode with a standard film applicator. The applicator is driven by a motor, so the coating speed is stable and adjustable.
3. Stepless Stroke and Speed Settings in the Touch Screen: The coating stroke is 300 mm, set and adjusted steplessly in the touch screen; the coating drive is motor-driven, with the coating speed also set and adjusted steplessly in the touch screen within the range of 0-120 mm/s (e.g., for lithium iron phosphate slurry).
4. Vacuum Aluminum Plate for Deformation-Free Substrate Holding: The vacuum aluminum plate measures L365 mm x W200 mm x H23 mm. Copper foil, aluminum foil, and similar substrates can be placed or removed quickly, and the substrate is adsorbed without deformation. Vacuum is supplied by the built-in oil-free vacuum pump (1 unit) or by an external vacuum source.
5. Standard Film Applicator with High Coating Precision: The standard film applicator provides high coating precision and adjustable coating thickness - the scraper thickness is adjustable within 0-6 mm, the coating accuracy is ±3 µm, and an optional 1 µm dial indicator is available for finer thickness reading.
6. Coating Width 100 mm (Can Be Enlarged): The standard coating width is 100 mm and can be enlarged. Optional scraper bars and other metering devices are available for manual coating.
7. Glovebox-Compatible and Space-Saving: The machine can be used inside a glovebox. Operation is convenient, and the small dimensions - L560 mm x W420 mm x H370 mm - save space.
8. PLC + Touch Screen Control: The machine is controlled by PLC and touch screen, making the setting of each parameter convenient.

Configuration Options

• Coating width: standard 100 mm; can be enlarged.
• Metering devices: optional scraper bar and other metering devices (manual coating).
• Vacuum source: built-in oil-free vacuum pump (1 unit), or connection to an external vacuum source.
• Thickness reading: optional 1 µm dial indicator.

The final configuration for a given order is defined at order confirmation.

Practical Operating Recommendations

• Substrate and vacuum: place the substrate on the vacuum aluminum plate and turn on the vacuum (built-in oil-free vacuum pump or an external vacuum source). The substrate is adsorbed without deformation; confirm that it lies flat before coating.
• Setting the coating parameters: set the coating stroke (300 mm, stepless) and the coating speed (0-120 mm/s, stepless) in the touch screen, and set the required coating thickness on the standard film applicator within the 0-6 mm adjustable range.
• Coating: the applicator is driven by the motor along the stroke at the set speed. The coating speed is stable and adjustable, so runs made with the same settings can be repeated.
• Drying: set the drying temperature on the digital display temperature controller (room temperature to 130 °C, accuracy ±1 °C). Large-area infrared heating keeps the chamber temperature uniform during drying.
• Thickness verification: the coating accuracy is ±3 µm; an optional 1 µm dial indicator can be fitted when a finer thickness reading is needed.
• Glovebox use: the machine can be used inside a glovebox; check the glovebox working space against the machine dimensions (L560 mm x W420 mm x H370 mm) before installation.
• Utilities: the machine runs on 220 V / 50 Hz with a power of 1.5 kW; confirm the supply at the installation site before commissioning.
• Cleaning after use: keep the machine and the vacuum plate clean; wipe with a soft cloth moistened with alcohol (see Maintenance and Precautions).

Maintenance and Precautions

1. Frequently wipe the machine with a soft cloth moistened with alcohol to keep it clean.
2. Apply oil to the moving parts for lubrication, to keep movement smooth.
3. If the machine will not be used for a long time, wipe the surfaces of the moving parts clean and spray anti-rust oil on the surfaces for protection.
4. Periodically check the screws, nuts, pins, and other fasteners at each position of the machine to prevent loosening, and to eliminate machine quality accidents and personal injury accidents.
