Benchtop Slot Die Flat Plate Coater Battery Laboratory Coating Machine

Product Overview

This benchtop slot die flat plate coating system is designed for controlled surface coating of sheet substrates used in laboratory-scale materials development. Its primary coating method is slot die extrusion, with optional blade coating, four-sided film applicator coating, and wire rod coating processes. The equipment combines stable motorized movement, sealed material delivery, vacuum substrate fixation, adjustable coating thickness, and integrated heating in a compact laboratory platform.

The system supports lithium-ion battery electrode substrates, solar photovoltaic films, polymer conductive films, OLED materials, and other functional thin-film research. It is suitable for battery R&D laboratories, universities, pilot process development, advanced materials research, and controlled formulation testing where repeatable coating conditions are essential.

A rigid flat-plate structure, precision adjustment mechanism, enclosed syringe feeding path, and broad-area heating system help maintain consistent coating quality under demanding experimental conditions. Touchscreen and PLC control simplify parameter adjustment, storage, and repeat operation, while the compact footprint allows installation inside a glove box for controlled-atmosphere work.

Key Features

• High-Precision Slot Die Coating: The extrusion coating process delivers high coating precision and strong film-to-film consistency, supporting controlled deposition of battery and functional material slurries.

• Stable Motorized Coating Drive: Motor-driven movement maintains a steady, adjustable coating speed. The operator can set coating speed continuously through the touchscreen for controlled process development.

• Sealed Syringe Material Feeding: A plunger-driven stainless steel syringe provides enclosed material delivery with minimal exposure to outside interference. The controlled feed path reduces material demand and coating waste during small-batch experiments.

• Integrated Vacuum Fixation: The vacuum aluminum flat plate holds the substrate securely throughout coating. Built-in vacuum generation helps prevent substrate movement, wrinkling, or shifting during the coating pass.

• Adjustable Film Thickness: The coating head thickness can be adjusted from 0 to 5 mm, allowing researchers to configure the wet-film condition for different slurry viscosities, substrate types, and process objectives.

• Uniform Heating and Drying: A broad-area heating system promotes even temperature distribution within the chamber. Digital temperature control operates from room temperature to 130°C with temperature accuracy of ±1°C.

• Compact Glove Box Compatibility: The small benchtop configuration is convenient for glove-box installation and controlled-atmosphere processing. Its compact structure helps conserve valuable laboratory space while preserving automated coating functions.

• Fast Cleaning and Changeover: The coating die and feeding system can be removed and cleaned conveniently. This is valuable when processing multiple formulations or switching between active materials, binders, solvents, and conductive additives.

• PLC Touchscreen Operation: The control interface supports convenient parameter adjustment, storage, and process control. Operators can configure travel, speed, and heating conditions through a centralized touchscreen interface.

Applications

Technical Specifications

The equipment is supplied as a slot die flat plate coating system with a standard film applicator and plunger pump feeding unit. The following specifications cover the available travel variants and shared process capabilities.

The short-travel configuration is suited to compact samples, small electrode sections, and glove-box environments where available space is limited. Its approximately 250 mm stroke provides a focused working area for routine laboratory coating and formulation screening. The extended-travel configuration supports coating lengths from 0 to 800 mm and offers a larger vacuum plate for longer substrates or broader process trials.

Operation follows a straightforward sequence. First, the operator places the electrode or sheet substrate on the vacuum plate, switches on the equipment, and activates vacuum fixation. The substrate is held against the plate while the coating applicator is positioned on its surface. After the coating cycle starts, the motorized coating mechanism moves the applicator across the substrate automatically.

After coating, the operator removes the applicator and push rod, closes the heating cover, and sets the required heating temperature and time. The integrated heating system then supports drying under controlled conditions. Once drying is complete, the cover is opened, the coated substrate is removed, and the coating mechanism is returned to its original position.

For dependable operation, the coating head, machine body, and other working surfaces should be carefully wiped with a soft cloth moistened with alcohol before each work session. Precision areas such as the coating head and micrometer mechanism must be handled carefully and protected from impact. When adjusting the micrometer, both sides should be adjusted symmetrically and evenly.

Routine inspection should include screws, nuts, pins, and other fasteners at all equipment locations. Checking these components regularly helps prevent loosening and reduces the risk of coating-quality incidents. Cleaning and inspection are particularly important when the system is used with different slurry chemistries or in repeated experimental cycles.
