PROBLEM TO BE SOLVED: To provide a manufacturing method of a cross-linked rubber molding having a superior compression set characteristic which can recycle materials in continuous molding by a melt process, and molding process.SOLUTION: A manufacturing method of a cross-linked rubber molding includes a first cross-linking step of getting a moldable first cross-linking body by cross-linking rubber compositions containing cross-linking rubber element partially, and a second cross-linking step of getting a second cross-linking body by cross-linking the first cross-linking body by ionizing radiation. Including an additional molding step forming the first cross-linking body between the first cross-linking step and the second cross-linking step is preferable. |
