A sensor ring for sensing speed of vehicle in anti-lock brake system is provided to be manufactured by compound mixing the plastic resin and ferrite powder, so it is light, high elastic and low brittle. A sensor ring for sensing speed of vehicle in anti-lock brake system is made of mixing ingredient of metal and plastic resin. The sensor ring manufacturing method is comprised of steps: producing the compound by mixing the plastic resin and metal powder; injecting and molding the compound through the sensor ring form; magnetizing the object which is formed by injecting and molding. |
