Material flows by backward extrusion permitting large deformation at high speed and thin-walled lightweight cylinders are produced. This process is more efficient than deep drawing

  • What Are The Advantages Of Using Deep Drawn

    The deep drawn solution eliminates issues associated with another method of enclosure manufacturing known as impact extrusion. The shortfall with impact extruded enclosures is that there is no draft angle along the sidewalls. This creates a challenge when assembling internal components or when using the enclosure as a mold.

  • Thermoforming Design Guidelines

    Deep parts and molded in textures require added draft . Parts designed to fully nest within each other should have 7 to 10 Degrees draft. Draw Ratio The draw ratio is the depth of the part divided by the narrower of width or length. In general the draw ratio should be restricted to 1 1. Deeper draw ratios can sometimes be accomplished utilizing
