A method of injection molding material around the surface of an object. The method involves positioning the object within the cavity of a first mold and holding the object through the use of a plurality of clamping mechanisms. Material is injection molded about the surface of the object such that the material encompasses the object's surface except for points of contact between the clamping mechanisms and the object. A plurality of protrusions, formed of injection molded material and extending outwardly from the surface of the object, are formed during the injection molding process. Thereafter the object is removed from the first mold cavity and positioned within the cavity of a second mold. The object is secured within the second mold cavity through engagement of the outwardly extending protrusions with the second mold. Additional material is then injection molded about the surface of the object with the additional material encompassing the object except for points of contact between the outwardly extending protrusions and the second mold.
