A method for manufacturing an insulated conductive material, the method including providing a wire, applying a masking material to one or more regions of the wire, coating regions of the wire other than the one or more regions with an insulating material by, electrically charging the wire with a first charge polarity, providing a medium of electrically charged insulating material particles that are charged with an opposite polarity, passing the charged wire through the medium, whereby the insulating material particles bind areas of the conductive material other than the one or more regions, curing the insulating material particles, and applying a solvent to the masking material to thereby remove the masking material, wherein the cured insulated material particles are substantially unaffected by the solvent.

A skinning apparatus and a method of skinning a porous ceramic. The apparatus includes an axial skinning manifold. The axial skinning manifold includes a curved adaptive pipe to flow cement in a circumferential direction from an inlet at a first position and through an adaptive opening along an inner bend of the curve through a land channel disposed along the inner bend. The land channel emits the cement at a constant velocity from a land opening extending proximate the first position to a second position spaced apart from the first position. The land outlet emits cement at a constant velocity around the outer periphery of the porous ceramic to dispose a uniform skin thereon as the porous ceramic moves axially relative to the land outlet.

A die with alignment mechanism includes a die including a through-hole through which a traveling wire travels, a bearing member for rotationally moving the die in a circumferential direction of the traveling wire, and a movable member that moves the die so that a central axis of the through-hole is aligned with a travel direction of the traveling wire without inhibiting the rotational movement of the die produced by the bearing member when the travel direction changes in a direction orthogonal to the travel direction.
