A method for making distinguishable mark on objects includes a step of making an annular groove in an outer surface of an object; a step of connecting a ring in the annular groove, and a step of heating and shrinking the ring to shrink the ring which is securely engaged with the annular groove. The ring can be printed with brand name, specifications or module number.
