Automatic Film Coating and Drying Machine

Automatic Coating and Drying Machine for High-Temperature Film Research - TOB-VCH-300X200

Product Overview and Ideal Applications

The TOB-VCH-300X200 is an automatic coating and drying machine. This product is widely used for various high-temperature film-coating research applications, including ceramic thin films, crystalline thin films, battery-material thin films, and specialty nano thin films. It is well suited to keep pace with future developments in science and technology requiring film formation under high-temperature conditions.

Coating uses the flat-plate coating mode with motor-driven scraper coating, so the coating speed is stable and adjustable. The coating travel of approx. 300 mm and the coating speed of 0-120 mm/s are steplessly set and adjusted via the touch screen, the scraper thickness is adjustable from 0 to 6 mm, and the coating precision is ±3 μm - with an optional 1 μm dial indicator with digital display for finer thickness reading.

The substrate is held on an aluminum vacuum flat plate measuring L 415 mm x W 250 mm x H 23 mm. The vacuum aluminum chuck allows quick placement and removal of copper foil, aluminum foil, etc. Vacuum is provided by the built-in oil-free vacuum pump (1 unit included) or by connection to an external vacuum source, with no substrate deformation during adsorption, and the machine comes standard with a film applicator - coating width 100 mm, with optional 150 mm or 200 mm applicators (maximum coating width 200 mm) and optional wire-wound rod and other metering devices for manual coating.

After coating, the film is dried by the heating and drying system, which covers room temperature to 130 °C with a digital temperature controller of ±2 °C accuracy; large-area uniform heating ensures high-precision temperature uniformity inside the chamber. The machine can be used inside a glove box, and its compact footprint - approx. L 560 mm x W 470 mm x H 370 mm, 38 kg - saves space. All parameters are set conveniently through PLC control with the touch-screen interface.

Ideal for:

• High-temperature film-coating research applications - ceramic thin films, crystalline thin films, battery-material thin films, and specialty nano thin films.
• Research that requires film formation under high-temperature conditions, keeping pace with future developments in science and technology.
• Laboratory work where coating and drying are carried out on one compact machine that can be used inside a glove box and saves space.
• Substrates such as copper foil and aluminum foil that must be held flat on a vacuum aluminum chuck, with no substrate deformation during adsorption.
• Processes that require flat-plate coating with motor-driven scraper coating at a stable and adjustable coating speed, with all parameters set via the PLC touch-screen interface.

Where Coating and Drying Fit 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 under controlled temperature to form the film. Ceramic thin films, crystalline thin films, battery-material thin films, and specialty nano thin films all depend on this sequence - and the equipment is well suited to keep pace with future developments in science and technology requiring film formation under high-temperature conditions.

The TOB-VCH-300X200 performs this sequence on a single machine:

1. Substrate placement: copper foil, aluminum foil, etc. are placed on the vacuum aluminum chuck and held flat by vacuum, supplied by the built-in oil-free vacuum pump or an external vacuum source - with no substrate deformation during adsorption.
2. Parameter setting: the coating travel (approx. 300 mm, stepless) and the coating speed (0-120 mm/s, stepless) are set and adjusted via the touch screen, and the coating thickness is set on the standard film applicator within the 0-6 mm scraper thickness adjustment range.
3. Coating: the scraper is motor-driven along the travel at the set speed in the flat-plate coating mode, so the coating speed is stable and adjustable.
4. Drying: the heating and drying system dries the coated film from room temperature up to 130 °C, with the digital temperature controller holding an accuracy of ±2 °C; large-area uniform heating ensures high-precision temperature uniformity inside the chamber.
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 used inside a glove box, so the same coating and drying sequence can be carried out in a controlled atmosphere - with easy operation and a compact footprint that saves space.

Practical Operating Recommendations

• Substrate and vacuum: place the copper foil, aluminum foil, etc. on the vacuum aluminum chuck; vacuum is supplied by the built-in oil-free vacuum pump (1 unit) or an external vacuum source, and there is no substrate deformation during adsorption. Confirm that the substrate is held flat before coating.
• Parameter setting: set the coating travel (approx. 300 mm, stepless) and the coating speed (0-120 mm/s, stepless) via the touch screen; the machine is controlled by PLC with a touch-screen interface, convenient for setting all parameters.
• Coating thickness: adjust the scraper within the 0-6 mm range; the coating precision is ±3 μm. Where a finer thickness reading is needed, use the optional 1 μm dial indicator with digital display.
• Drying: set the drying temperature within room temperature to 130 °C on the digital temperature controller (accuracy ±2 °C); large-area uniform heating ensures high-precision temperature uniformity inside the chamber.
• Coating width selection: the standard film applicator provides a coating width of 100 mm; optional 150 mm or 200 mm applicators are available (maximum coating width 200 mm), and optional wire-wound rod and other metering devices can be used for manual coating.
• Glove box use: the machine can be used inside a glove box; check the glove box working space against the machine dimensions (approx. L 560 mm x W 470 mm x H 370 mm, 38 kg) 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.
• Care and safety: wipe the equipment regularly with a soft cloth moistened with alcohol, lubricate moving parts, apply anti-rust oil for extended idle periods, and check fasteners periodically (see Maintenance); during operation, hands or other body parts must not be inserted into moving parts or working danger zones (see Cautions).
