XIAMENDoctor Blade Coating Machine for Battery Electrode | Continuous Lab Coater TOB-KD200
Product Overview
The TOB-KD200 Doctor Blade Coating Machine is a high-precision continuous coating system designed for laboratory research and pilot-scale production of battery electrodes and functional films.
This machine adopts a continuous doctor blade (comma blade) coating method, enabling precise thickness control and excellent coating uniformity. It is widely used in the coating process of lithium-ion batteries, supercapacitors, nickel batteries, and other advanced energy storage materials.
Equipped with a dual-side hot air drying system, automatic tension control, and PLC intelligent operation, the TOB-KD200 ensures stable coating performance comparable to production-level equipment, making it an ideal choice for research institutions and industrial laboratories.
