An unconventional injection-molded insulator for the corepiece of MnZn ferrite slider (recording head) is described. The features of this molded insulator are that it locks onto the corepiece and covers the sharp edges of the ferrite core. The purpose of the insulator is to prevent the copper wires of the coil from making contact with the fer (Image Omitted) rite corepiece. Without the use of an insulator this can occur frequently due to the copper wire's own insulation being stripped off or nicked while the coil is being wound onto the corepiece. The one-piece injection-molded insulator and runner, shown as top and side views in Fig. 1, has three distinct portions: the left half insulator 1, the hinged runner 2 and the right half insulator 3. In Fig. 2, there is a front and back view of one of the half insulators.
