Small Laboratory Automatic Film Coating Drying Machine

Product Overview

This small laboratory automatic film coating drying machine combines precision flat-bed coating with controlled heated drying in a compact laboratory platform. Motor-driven coating provides stable, adjustable movement, while the supplied film applicator supports controlled coating thickness. A vacuum aluminum plate holds copper foil, aluminum foil, and other substrates securely during processing without deformation.

The equipment is designed for high-temperature film research involving ceramic films, crystal films, battery-material films, and special nanofilms. Its compact dimensions allow transfer through a glove box pass-through chamber, making it suitable for controlled-atmosphere workflows. The unit can also be operated inside a glove box when connected to an external vacuum pump.

Large-area uniform heating supports accurate temperature uniformity throughout the chamber, while the digital temperature controller provides controlled drying from room temperature to 130°C. PLC and touch-screen operation simplify parameter setting, helping laboratories maintain repeatable coating and drying conditions during demanding materials research.

Key Features

• Compact Glove Box Compatible Design: The small footprint allows the equipment to pass through a glove box transition chamber. Its compact external dimensions also help conserve valuable laboratory and controlled-environment workspace.

• Motor-Driven Flat-Bed Coating: The coating blade is driven by a motor to maintain stable movement across the substrate. Coating speed can be adjusted continuously through the touch screen for controlled process development.

• Adjustable Coating Speed: The coating speed range is 0 to 120 mm/s when processing materials such as lithium iron phosphate slurry. This adjustable range supports process optimization across different slurry and film research conditions.

• Precision Film Thickness Control: The supplied film applicator enables adjustable coating thickness, with a blade thickness adjustment range of 0 to 5 mm. Coating precision reaches ±3 μm, with an optional displayed 1 μm dial indicator available for enhanced measurement visibility.

• Vacuum Aluminum Substrate Plate: The vacuum plate rapidly accepts or releases copper foil, aluminum foil, and similar substrates. Vacuum fixation helps prevent substrate deformation during coating and supports stable positioning across the working area.

• Flexible Vacuum Supply: An oil-free vacuum pump is included and built into the equipment. When the unit is installed inside a glove box, an external vacuum pump is required to support the vacuum plate.

• Uniform Heated Drying: Large-area heating is used to promote accurate temperature uniformity inside the chamber. The drying system operates from room temperature to 130°C with temperature control accuracy of ±1°C.

• Touch-Screen PLC Control: PLC-based touch-screen control provides a convenient interface for setting coating speed, coating travel, and temperature-related operating parameters. Coating travel can be adjusted continuously through the control screen.

• Space-Efficient Laboratory Construction: The compact enclosure integrates coating, vacuum fixation, and heated drying functions in a 0.4 kW system. This configuration supports efficient use of bench space for laboratory-scale film preparation.

Applications

Technical Specifications

The maximum coating area is 200 mm in length by 100 mm in width, providing a defined working zone for laboratory-scale film preparation. Coating travel is set through the touch screen and can be adjusted continuously, allowing users to match the active stroke to the substrate size and formulation requirements. This is useful when the same research workflow involves multiple sample dimensions or coating lengths.

The motor-driven coating mechanism is designed to provide stable travel across the flat bed. The adjustable coating speed extends from 0 to 120 mm/s, with lithium iron phosphate slurry identified as a representative application material in the reference specifications. Because speed is adjusted through the touch screen, operators can establish repeatable process settings without relying on manual movement.

The standard film applicator is identified as a 100 film applicator in the supplied specifications. Other metering tools, including coating rods, can be selected for manual doctor-blade coating. This gives laboratories flexibility when comparing coating methods, testing different slurry behaviors, or adapting the equipment to specialized film formulations. The blade thickness adjustment range is 0 to 5 mm, while coating precision is specified as ±3 μm.

For applications requiring additional visible thickness measurement, a 1 μm dial indicator is available as an option. This provides a more detailed displayed measurement reference for users who need greater control when setting or monitoring the coating gap. The combination of adjustable blade thickness, selectable metering tools, and motorized travel supports structured process development rather than one fixed coating condition.

The vacuum aluminum flat plate measures 230 mm in length, 130 mm in width, and 30 mm in height. It is intended for rapid placement and removal of copper foil, aluminum foil, and other substrates. Vacuum fixation helps hold the base material in position during the coating pass and is designed to avoid deformation of the substrate. The equipment includes one built-in oil-free vacuum pump. For operation inside a glove box, the reference specifications require connection to an external vacuum pump.

The integrated heated drying system operates from room temperature to 130°C and uses a digital temperature controller. Temperature control accuracy is specified as ±1°C. Large-area uniform heating is used to promote accurate temperature uniformity within the chamber, supporting consistent drying conditions across the working area. This capability is relevant to high-temperature coating research involving ceramic, crystal, battery-material, and special nanofilm samples.

The power requirement is 220 V at 50 Hz, and rated power is 0.4 kW. The unit weighs 15 kg and has external dimensions of 375 mm in length, 225 mm in width, and 190 mm in height. These dimensions support bench-top deployment and transfer through a glove box transition chamber. PLC and touch-screen control provide the operating interface for convenient parameter setting, including coating travel and coating speed adjustments.
