Specializing in roll-to-roll coating equipment

CO-TECH is a global manufacturer of industrial coating equipment, which continuously pursues advancement of technology and development of innovative products to win customers' satisfaction and trust.
Secondary Battery Separator COATER
This facility blocks contact between the cathode and the anode in the secondary battery, thereby strengthening heat resistance and strength to stabilize the battery. It is a coating facility that produces a separator through which lithium ions in the electrolyte can pass. The coating method realizes double-sided simultaneous coating with nano coating, and can easily change the coating amount by replacing the bar and fine-adjust the coating amount by adjusting the rotation speed. In addition, surface treatment technology such as corona is applied so that it can be coated uniformly for porous substrates.



Secondary Battery Electrode COATER
This equipment is for the production of secondary batteries (lithium-ion polymer batteries). The active substances mixed in Cu-Foil or Al-Foil are continuously coated on the substrate at regular intervals and thickness using slot die head. The cathode material, which is a source of lithium, determines the capacity and average voltage of the battery, and the anode material serves to allow current to flow through an external circuit while storing and discharging lithium ions from the cathode. Currently, lithium-ion battery facilities focus on maximizing productivity by driving wide substrates at high speed, and our company has developed and applied various technologies to respond to this demand.

Release Film COATER
This facility is a coating facility that produces high-quality high-performance films such as MLCC, polarization film, and OCA. Anti-Vibration for ultra-fast, thin-film and wide-width production, film wrinkles, and scratch-resistant technologies are applied to produce optimal release films. Currently, it is increasing significantly as it is applied and expanded in various fields such as mobile phones, displays, and solar cells, and accordingly, the demand for release film coatingers is also increasing. Through the development of new technologies, CO-TEC Co., Ltd. strives to supply coating machines for stable, high-quality, and fast silicon release films, and designs and provides products with optimal conditions to meet customer needs.
