ABSTRACT:
A plastic part forming apparatus includes a mold tunnel into which molten plastic is fed to form the plastic part. The mold tunnel is made from thermally conductive material and has a part shaping interior face which is non-reflective such that the interior surface has high capacity to absorb heat energy from the plastic fed into the mold tunnel. The thermally conductive material then dissipates the heat energy from the mold tunnel.
