IMPROVED SHOT PEENED PRESS PLATE AND METHOD OF PRODUCING SAME

摘要

Shot peening with a mixture of at least two sizes of shot can be used to obtain a textured finish press plate with desirable gloss features. The press plate is impacted with a mixture of shot having at least two different sizes to simultaneously obtain a texture and gloss control. A separate overblasting step to obtain a desired gloss uniformity is thereby avoided.
