Production of mold charge of elastomeric material containing magnetic oxide filler |
摘要 |
A method for preforming magnetic drum material involves the use of a hydraulic press and sleeve which in turn compresses the material and then cuts the material into a specific shape. This process is repeated until the material builds up in the sleeve to the required charge thickness. This method has improved the molding process by eliminating air and gas voids in the molded magnetic drum.
