A mechanical interlocking die has a first surface, a second surface, a plurality of extrusion features, and a plurality of channels. The first surface and the second surface each extend in a longitudinal direction. Each of the extrusion features includes a base portion extending in a cross-sectional plane from the first surface, wherein the cross-sectional plane is substantially normal to the longitudinal direction, and an arm portion extending at an angle in the cross-sectional plane from the base portion. Each channel extends at an angle to the longitudinal direction from the second surface, and is disposed between a pair of extrusion features.
