Bottom Heating Film Coating Machine

Product Overview

This bottom heating film coating machine is designed for high-temperature coating research involving ceramic films, crystal films, battery material films, and specialized nano films. Its integrated coating, vacuum fixation, and bottom heating functions support controlled film formation and drying in a compact laboratory system. The equipment is suited to research programs investigating future film-forming technologies under elevated-temperature conditions.

The system combines programmable coating movement with a vacuum aluminum plate and adjustable heating. Researchers can set coating speed, travel distance, heating temperature, and drying time through the touch-screen interface. This makes the unit suitable for electrode preparation, functional film development, advanced materials studies, and laboratory-scale process evaluation.

A precision micrometer blade, rigid sheet-metal structure, digital temperature control, and oil-free vacuum pump provide a practical foundation for repeatable work. The equipment is configured for laboratory environments where controlled coating thickness, stable substrate positioning, compact dimensions, and straightforward operation are important to daily research productivity.

Key Features

• Bottom Heating and Drying: The integrated vacuum plate heating system operates from room temperature to 150°C. A digital temperature controller provides temperature control accuracy of ±1°C for consistent drying conditions after coating.

• Micrometer Level Thickness Control: The adjustable blade has a thickness setting range of 0 to 5 mm and coating thickness control accuracy of 0.01 mm. This supports precise preparation of research films and electrode coatings.

• Adjustable Coating Speed: Coating speed can be adjusted from 0 to 120 mm per second. Researchers can match the coating motion to slurry behavior, target film thickness, and process development requirements.

• PLC and Touch Screen Control: PLC-based operation and a touch-screen interface make parameter setting and observation convenient. The coating stroke from 0 to 300 mm can also be set through the touch screen.

• Vacuum Substrate Fixation: The vacuum aluminum flat plate holds the substrate securely during coating. Rapid placement and removal help streamline sample preparation and reduce unnecessary handling.

• 100 mm Standard Coating Width: The standard coating device width is 100 mm, providing a practical working format for laboratory film and electrode research while maintaining a compact equipment footprint.

• Compact Structural Design: Overall dimensions of L550 mm × W350 mm × H320 mm help conserve valuable laboratory space. The three-dimensional geometric sheet-metal design provides a clean appearance and organized equipment structure.

• Integrated Vacuum Supply: One oil-free vacuum pump is included with the equipment. This provides a dedicated vacuum source for substrate fixation without requiring an additional pump selection for standard operation.

Operating Procedure

The operating sequence separates substrate fixation, slurry coating, and heated drying into clear stages. This arrangement allows researchers to prepare a sample, complete the programmed coating movement, and then apply the selected drying condition without transferring the coated substrate to a separate heating platform. The vacuum plate remains the central work surface throughout the process, supporting stable handling of aluminum foil, copper foil, and other research substrates within the stated dimensional ranges.

The adjustable coating speed range enables process development across different slurry formulations and film objectives. Lower speeds can be selected for process evaluation where controlled material deposition is required, while higher speeds support faster sample preparation when the formulation and target coating condition permit. Blade adjustment and coating stroke settings can be configured from the touch screen, allowing the operator to establish a repeatable starting point for comparative experiments.

The bottom heating function is particularly relevant to research programs that study drying and film formation at elevated temperatures. The digital controller displays the selected temperature, and the stated ±1°C control accuracy supports consistent thermal conditions between experiments. Because the heating system is integrated beneath the vacuum plate, the coated substrate can remain fixed during the drying stage, reducing additional movement during sample preparation.

The physical design is also suited to laboratories with limited bench space. The L550 mm × W350 mm × H320 mm footprint combines the coating mechanism, vacuum plate, heating system, controls, and included vacuum pump in a compact format. The rigid sheet-metal enclosure uses a three-dimensional geometric design that presents a clean, organized appearance while protecting the internal equipment structure during routine laboratory use.

Why Choose This Product

• Integrated Research Workflow: Vacuum fixation, programmable coating, adjustable blade control, and bottom heating are combined in one unit, reducing transfers between separate preparation stages.

• Repeatable Process Control: Adjustable coating speed, 0.01 mm coating thickness control accuracy, programmable 0 to 300 mm stroke, and ±1°C temperature control accuracy provide measurable process settings for comparative research.

• Substrate Stability: The vacuum aluminum flat plate helps hold electrode sheets securely during coating and drying, supporting consistent sample handling across aluminum foil and copper foil studies.

• Efficient Laboratory Footprint: Compact overall dimensions and the included oil-free vacuum pump simplify installation where bench space and equipment integration are important considerations.
