Abstract
A method of manufacturing a shim for a die coater is disclosed herein. In some embodiments, a method of manufacturing a shim for a die coater, where the shim is applied to an electrode slurry die of the die coater and used for discharging an electrode slurry from the die coater, comprising milling a surface of a metal plate to prepare the shim. Using the method herein, it is possible to manufacture a shim for a die coater having a low thickness deviation by processing the shim for a die coater through a milling process.
Claims10
A method of manufacturing a shim for a die coater, where the shim is applied to an electrode slurry die of the die coater and used for discharging an electrode slurry from the die coater, the method comprising:
- milling a surface of a metal plate to prepare the shim,
- wherein the milling of the surface of the metal plate comprises cutting the metal plate to form a slurry discharge line defined by an open region between opposing surfaces of a first guide and a second guide, the open region having a downstream portion and an upstream portion, the upstream portion being wider along a lateral dimension than the downstream portion, the lateral dimension being perpendicular to upstream and downstream directions, and the open region extending to a discharge port along a downstream-most edge of the shim;
- and
- cutting a step along each of the opposing surfaces of the first and second guides such that the step extends along an entirety of the downstream portion of the open region between the upstream portion and the discharge port.
