<p>A support structure (40) for a PCD element comprises a support (42) into which a plurality of PCD elements are locatable, and a plurality of sealing elements (48) for location in the support structure. Each sealing element (48) is configured to protect a non-leached portion of an associated PCD element during a leaching process, said support being formed from or coated with a polyketone based plastics material. A plurality of support structures (42) may be stacked on top of each other and a central support rod (52) is locatable in a central aperture (50) extending though the stack of support structures (42). A handle (54) may be attached to the central support rod (52) for ease of transporting the assembled support structure.</p> |
