The method of manufacturing a handle grip of a tool comprises the steps of: 1. to position a mandrel of a manufacturing machine and to inject plastic material to form an inner layer; 2. to release the positioning to leave positioning holes on the shaped inner layer, the inner layer then is processed by second time injection to completely envelop the inner layer with plastic and shape a middle layer; and 3. the middle layer being processed by third time injection to partially envelop the middle layer with plastic to thereby form an external layer with the middle layer partially exposed, and the handle grip of the tool with two colors in firm combining state being completed. On the handle grip made by these steps, the holes formed after taking off the mandrel of the manufacturing machine are holes for combining the stem of the tool; hence the holes made are not subjected to twisting and deformation, and is convenient for combining with the stem. Using this process, a handle grip of the tool with plural colors can be produced. |
