<p>A method for manufacturing magnetic rollers and a system thereof relates to technology for manufacturing magnetic rollers for developing apparatus. The method for manufacturing a magnetic roller comprises the following steps: Step 1: determining number and shape of magnets required according to a desired magnetic field distribution diagram, and thereafter mounting the magnets around a cavity of a mold at corresponding positions required for attaining the desired magnetic field distribution diagram; Step 2: injecting materials for manufacturing the magnetic roller into the cavity of the mold for molding to manufacture the magnetic roller; at the same time, magnetizing the magnetic roller inside the mold so that the magnetic roller manufactured has a magnetic field distribution diagram identical to the desired magnetic field distribution diagram mentioned in Step 1. The system used in the method for manufacturing magnetic rollers comprises a mold, wherein the mold comprises a cavity and magnets; the magnets are distributed around the cavity of the mold according to a desired magnetic field distribution diagram. The advantages of the present invention are as follows: capable of integrally molding magnetic rollers, capable of attaining extremely complex magnetic field distribution diagrams, simple manufacturing process, short production cycles, high production efficiency, low production costs, energy-saving and so forth.</p> |
