The coating die is often referred to as the "heart" of a coater—it is an essential component for high-speed, precision coating and a critical device for improving product quality and yield.

According to GGII (Gaogong Lithium Battery), with the rapid growth of the new energy vehicle industry, there is increasing demand for higher capacity and enhanced performance of power batteries. This, in turn, imposes stricter requirements on coating processes—covering speed, efficiency, yield, and cost. For example: coating speeds must reach 80–120 m/min; cleaning and changeover time should be less than 1 hour; setup time under 15 minutes; real-time monitoring and adjustment capabilities; and reduced commissioning costs.

This means that conventional coating technologies can no longer meet the demands of power battery manufacturers. Indeed, leading companies such as CATL and BYD have already begun integrating new processes and equipment into their production lines.

As an innovative enterprise focused on coating technology R&D since its inception, the company has always taken “making coating simple” as its core mission—continuously addressing the evolving needs of power battery manufacturers in coating processes and championing the domestic substitution of coating dies.

Looking back over nearly a decade of development, in a market once dominated by imported coating dies, the company has carved out a foothold for domestic alternatives through solid technical capabilities, reliable customized solutions, and responsive service—leading the Chinese die market toward continuous breakthroughs.

From early single-layer coating dies featuring differential threads, micrometers, and push-pull rod adjustments, to advanced dual-layer and fully automatic coating dies, the company’s technological capabilities have consistently advanced. These achievements reflect its unwavering commitment to innovation since founding and underscore its growing value proposition throughout its development journey.
