Abstract
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.
Claims15
A press plate for producing decorative laminate having a textured surface formed by shot peening the surface simultaneously with a mixture of shot particles,
- the mixture of shot particles including a first quantity of shot comprising shot grades for imparting a texture to the surface and a second quantity of shot comprising shot grades for adjusting a gloss level of the surface of the plate.
A press plate for producing decorative laminate having a textured surface having at least 95% peened coverage by the simultaneous impact of a mixture of shot particles through no more than eight peening operations,
- the mixture of shot particles including a first quantity of shot comprising shot grades for imparting a texture to the surface and a second quantity of shot comprising shot grades for adjusting a gloss level of the surface of the plate.
A press plate for producing decorative laminate having a textured surface formed by shot peening the surface simultaneously with a mixture of ceramic shot particles,
- the mixture of ceramic shot particles including a first quantity of ceramic shot comprising shot grades for imparting a texture to the surface and a second quantity of ceramic shot comprising shot grades for adjusting a gloss level of the surface of the plate.
A press plate for producing decorative laminate having a textured surface having at least 95% peened coverage by the simultaneous impact of a mixture of ceramic shot particles through no more than four peening operations,
- the mixture of ceramic shot particles including a first quantity of ceramic shot comprising shot grades for imparting a texture to the surface and a second quantity of ceramic shot comprising shot grades for adjusting a gloss level of the surface of the plate.
