Described herein are methods for texturizing metal, closed-end, cylindrical workpieces or capsules. A texturizing apparatus that includes a texturizing sector and a texturizing spindle tip is disclosed. The metal, closed-end, cylindrical workpieces or capsules are placed onto the texturizing spindle tip that includes a texture. A pressure is applied to the texturizing sector and the metal, closed-end, cylindrical workpiece or capsule, and the texturizing spindle tip is rotated against the texturizing sector to impart an image of the texturizing spindle tip texture to the metal, closed-end, cylindrical workpiece or capsule. The texturizing sector may include a smooth surface and a resilient material, and the texturizing spindle tip may include a textured surface and a non-resilient material. The texture of the metal, closed-end, cylindrical workpiece or capsule includes the imparted image of the texturizing spindle tip texture.
