Abstract
A combination structure is composed of a hard body having a hollow interior, at least one recess defined in one side of the hard body, a soft material filling in the at least one recess and at least one bulge emerged from the hard body. By filling the soft material inside the hard body and forming the bulge, the soft material is protected by the hard body from torque deformation and provides the anti-slide efficiency. A method for making the combination structure is to hold the hard body within a mold and inject soft material into the mold, thereby, the combination structure is achieved.
Claims8
A method for making a combination structure with different materials, the method comprising:
- providing a hard body with a hollow inner body and at least one recess defined in at least one side of the hard body;
- holding the hard body within a mold, wherein the mold has at least one cavity correspondingly aligned with the at least one recess;
- and
- injecting soft material in form of liquid into the mold until the soft material completely fills the at least one recess and the at least one cavity, wherein the soft material in the lat least one cavity performs at least one bulge after solidification.
A combination structure with two different materials comprising:
- a hard body having at least one recess defined in at least one side of the hard body;
- and
- a soft material filled inside the bard body and has a bulge emerged out of the hard body.
