Encapsulation process of rubber coated magnet is processed via vulcanization or injection molding technology. Vulcanization and injection molding technology is corresponding to vulcanized silicon rubber and thermo-plastic-rubber material (TPR), respectively. Injection molding technology of rubber coated magnet is belonging to overmolding process which involves 2 separate molds. The first mold produces a rubber part with cavity for the magnetic system. Magnetic system is then placed into the first rubber part. The assembly is subsequently inserted into the second mold where the second half of rubber part in injected, covering the magnetic system and fusing with the first half of the rubber part. For rubber coated magnet, injection molding technology is the more conventional encapsulation process compared with vulcanization technology due to the production efficiency, raw material cost, utilization rate of recycled material, and color flexibility. Even vulcanization technology is generally condemned for relatively higher cost, but vulcanized silicon rubber coating can serve more superior durability and slide resistance to rubber coated magnet.
