Arc-Type Tungsten Carbide Drawing Dies Introduction

Tungsten carbide drawing dies mold core work area is rendered "arc-type" and thus make metal tungsten carbide drawing dies mold core deformation in the region even more tortuous flow leads to unnecessary additional shear deformation and deformation work increased so that the drawing stress in general than the "straight" Carbide drawing dies mold core work area increases by 10 to 30%, but "straight" Carbide drawing dies mold core work area each contour line the slope is the same point so that when we determined the optimum cone half-angle α workspace when you can pull the metal with minimal stress and drawing "arc-type" Carbide drawing dies due to the curvature of each point of its contour line different and therefore can not make the whole Carbide drawing dies mold core work area there is an optimal workspace cone half-angle α.
