With the rapid development of new energy technology, from lithium battery separators, functional coating films, to high-performance thin film materials, an increasing number of processes are affectingCoating thickness, uniformity, and repeatabilityPropose strict requirements. The traditional manual coating method often has problems such as unstable operation, large thickness fluctuations, and poor sample consistency. In this context,Automated and controllable coating solutionIt is becoming a key tool for research and quality control.

As the flagship coating equipment of TQC Sheen brand under Industrial Physics,AB4400 Automatic Coating MachineEquipped with a heated perforated vacuum bed, digital temperature control, 0.1-500 mm/s coating speed, and a comprehensive parameter controllable coating mechanism, specially designed for preparing high-quality and reproducible coating samples.

New energy research and developmentWhy is it neededAB4400？

In the era of rapid evolution of new energy materials and high permeability membrane technology, from lithium battery separators to functional thin film coatings, each coating may affect subsequent performance indicators such as moisture permeability, weather resistance, and adhesion. Therefore, achieving repeatability, quantifiability, and traceability in the coating process has become a key link that must be overcome in research and quality control. And AB4400 can be easily achieved——

From research and development to quality control,AB4400 full coverage

In coating research and quality control, high standards mean that international standards, industry norms, and internal consistency management must be taken into account. AB4400 can achieve:

Compliant with coating standards such as ASTM D823, ensuring coating effectiveness from the source;

Automatically save coating parameters (speed, start and end positions, temperature, vacuum status) and enable reusable settings, achieving consistent parameters between equipment and batches;

Establish a standardized coating process to build a complete process from sample preparation, quality control sampling, to performance evaluation, seamlessly connecting coating development and quality control.

In this process, the R&D team can focus on material and formula innovation, while the production or QC team can rely on a unified coating platform to ensure sample consistency and reduce the variable of "coating differences".

Model differences and comparisons:AB4400 andAB4120 / 4220

In order to adapt to different laboratory configurations or coating requirements,There are other models to choose from for the TQC Sheen automatic coating machine line. Here is an overview of the main differences:

Based on specific application scenarios (such as new material development vs. standard coating quality control), substrate type, whether heating is required, and budget conditions, you can choose the model that suits you.

Regarding the vacuum testing bench:Integrated guarantee of coating

In the research and development of new energy membrane materials and high moisture permeable coatings, sample preparation often faces several challenges:Difficulty in stable positioning of substrate, thickness fluctuations caused by micro displacement of coating surface, uneven heating of thermosensitive substrate or film during coating process, and defects caused by vibration or shaking during coating processThe perforated vacuum adsorption bed equipped on AB4400 is specifically designed to address these issues.

Stable adsorption, eliminating substrate movement

A vacuum bed can firmly adsorb films, substrates, or coated plates onto the platform, effectively preventing micro displacement of the substrate due to vibration, manual operation, or sliding during the coating process. In this way, the coating roller or scraper maintains consistency between the starting and ending positions, ensuring more controllable and repetitive changes in coating thickness.

Heating and vacuum in one, suitable for functional thin film coating

The vacuum bed not only provides adsorption, but also has a built-in heating pad that can raise the substrate temperature to ambient temperature+100 ° C (up to+125 ° C). For lithium battery separators, functional thin film coatings, solar film encapsulation layers, etc., preheating the substrate or coating in a hot state can often improve adhesion, improve coating quality, and reduce defect rates. At this point, the dual function of heating and vacuum makes AB4400 particularly suitable for the development of new energy coatings.

In addition, the AB4400 adsorption pore size is only 1 mm, which will not affect the film and cause uneven coating due to adsorption. It ensures smooth adsorption without causing damage to the film material.

Improve thickness consistency and optimize subsequent testing processes

After coating is completed, subsequent thickness measurements, moisture or air permeability tests, and thermal cycling tests are all based on sample consistency. The stable adsorption of the vacuum bed, second level positioning, and programmable trajectory control (speed, start stop position) significantly improve the repeatability of sample preparation. In this way, R&D personnel can focus on materials, formulas, and coating structures themselves without worrying about variable interference caused by coating.

In short, the vacuum bed is the cornerstone of the coating and sample preparation process, and AB4400 is the solution that integrates the vacuum bed with automatic trajectory coating, high temperature control, and more.

Industrial Physics for YouSuggestions for lithium battery coating application

Whether you are developing high permeability membranes, functional coating materials, or looking to establish a stable coating measurement process, AB4400 (or its series models) can provide you with critical support. We suggest that you start from the following aspects:

• In the laboratory stagePrepare the coating sample using AB4400 and combine it with subsequent coating thickness testing (such as coating thickness gauge) and moisture/air permeability testing to quickly determine the formulation parameters.

• During the quality control phaseSolidify the coating process and establish daily sample preparation standards to eliminate testing deviations caused by inconsistent coating.

• In the preparation stage before large-scale trial production or productionBuild a coating platform using series models (such as AB4220) to achieve repeatable coating processes, replaceable personnel, and uniform parameters.

In the era of new energy and thin film coating, each layer of coating should be a controllable process node. Choosing TQC Sheen AB4400, a coating equipment with automation, repeatability, and controllability, is a solid foundation for your coating products and processes.
