Against the backdrop of lithium battery manufacturing entering the TWh era, improving production capacity, yield, and consistency has become the core competitiveness of battery manufacturers. As the first critical process in electrode manufacturing, the quality of the coating process directly determines the battery’s energy density, safety, and cycle life.

Coating gaskets, also known as "baffles" or "cavity plates", are core precision tooling that determines coating width and edge shape. Installed on both sides of the coating die head, the contour accuracy, edge quality, and dimensional stability of their cavities are critical.

Product Features：

Special-shaped slits and trapezoidal cross-sections need to be processed, with both shape accuracy and hole-opening consistency guaranteed;

For ultra-thin gasket processing, flatness and thickness consistency of the gaskets must be ensured, with the overall thickness deviation not exceeding 0.003mm.
