  • Publication number: 20190184479
    Abstract: A grommet is configured to be secured onto a wiring harness even when the diameter of the wiring harness shrinks. The grommet includes a tubular body having an inner wall defining a through-hole which is dimensioned to hold the wiring harness. The grommet includes a hole configured to receive a soldering tip of a soldering iron. The hole is open at the outer surface of the first body member and closed by the inner wall, wherein the inner wall serves as a temporary barrier which prevents the soldering tip of the soldering iron from coming into direct contact with the wiring harness. Thus, the soldering tip can melt a portion of the inner wall to adhere the grommet to the wiring harness without damaging the wiring harness.

    Abstract: A method of producing a free standing PCD comprises forming a mass of combined diamond particles and precursor compound(s) for the metals of the metallic network by suspending the diamond particles in a liquid, and crystallising and/or precipitating the precursor compounds in the liquid. The mass is then removed from suspension by sedimentation and/or evaporation to form a dry powder of combined diamond particles and precursor compound(s). The powder is subjected to a heat treatment to dissociate and reduce the precursor compound(s) to form metal particles smaller in size than the diamond particles to provide a homogeneous mass. This is then consolidated using isostatic compaction to form a homogeneous cohesive green body of a pre-selected size and 3-dimensional shape.
