Abstract
Process for manufacturing a roll press jacket, wherein the roll press jacket includes a hollow cylindrical sleeve made of an castable elastomeric material containing at least one crystallization component, the sleeve has an interior cylindrical surface and an exterior cylindrical surface. The internal surface and the external surface have different hardness characteristics. The process includes using a cylindrical casting mold having an casting surface, the casting mold having a temperature which is maintained at a temperature colder than an elastomeric material being cast, casting a hollow cylindrical sleeve from the elastomeric material on the casting mold, the elastomeric material containing at least one crystallization component, providing the sleeve with an interior cylindrical surface and an exterior cylindrical surface, one of the internal or external surfaces being formed against the casting surface of the cylindrical casting mold, wherein the surface of the sleeve which is formed against the casting surface is harder than a surface which is not formed against the casting surface.
