1. Product Positioning & Main Applications

This compact vacuum coating machine is specially developed for continuous coating processes of cathode and anode electrodes of lithium-ion batteries. It is an ideal laboratory equipment for universities, research institutes and enterprises to conduct small-scale R&D and experimental tests. Besides battery electrode coating, it is also widely applicable for preparing ceramic films, crystal films, nano functional films and other special thin-film materials.

The whole machine adopts stainless steel structure with plastic-sprayed surface, featuring solid construction, excellent durability and user-friendly operation, perfectly adapting to frequent use in laboratory environments.

2. Core Technical Features & Performance Advantages

2.1 Transmission System: Stable & High-precision Operation

· Equipped with low-speed synchronous motors, delivering steady power output and avoiding uneven coating caused by speed fluctuation.

· Adopts imported high-precision ball screws and linear guide rails, which are standard configurations for high-end precision equipment. They ensure linear moving accuracy and smooth running without jitter or stalling during coating.

· The integrated precision transmission structure realizes micro-level positioning accuracy, laying a solid foundation for consistent and precise coating results.

2.2 Coating System: Reliable & Adjustable Coating Performance

· The coating doctor blade is made of premium SUS316L stainless steel, featuring outstanding corrosion resistance and wear resistance. It is compatible with various battery slurries including acidic and alkaline materials, and delivers neat edges and uniform coating layers.

· Adjustable coating thickness range: 0.01 ~ 3.5 mm, with an adjustment accuracy of 0.02 mm, meeting experimental requirements for ultra-thin to thick film coating.

· Maximum effective coating width reaches 100 mm, compatible with copper foils, aluminum foils and electrode sheets of common sizes for laboratory tests.

2.3 Heating & Drying System: Uniform & Efficient Drying

· Adopts forced hot air circulation drying system to realize homogeneous heating, effectively preventing coating cracking and material deterioration caused by local overheating.

· Digital temperature control system, adjustable from room temperature up to 150°C, with a high temperature control accuracy of ±1°C. It satisfies the drying process requirements of different slurries and coating materials.

· The heating platform is designed with optimized heat distribution, ensuring even temperature across the substrate and consistent drying effect.

2.4 Vacuum Adsorption System: Fast & Firm Substrate Fixing

· Built-in aluminum vacuum adsorption platform features light weight and good thermal conductivity. It can firmly hold substrates while facilitating heat transfer.

· Copper foils, aluminum foils and electrode sheets can be loaded and unloaded quickly without complex fixtures. The vacuum adsorption keeps substrates flat and fixed without displacement, wrinkles or warping during operation.

· Matched with an oil-free vacuum pump to provide stable vacuum suction, suitable for ultra-thin flexible substrates as well.

2.5 Humanized Design & Extra Functions

· Coating speed is digitally adjustable within 0 ~ 100 mm/s. Users can flexibly set the speed according to slurry viscosity, coating thickness and process requirements.

· Designed with a removable cover, which brings great convenience for daily operation, equipment cleaning and routine maintenance. Users can choose to work with or without the cover as needed.

· Built-in UV lamp module supports UV curing processes for special coatings, greatly expanding the application scope of the equipment.
