The titanium material using a mold of a rigid

 Cutting - like a ttitanium valve punch in the desired shape punched out the hair department. Concentric shape of titanium, the maximum cutting thickness of 3.2 mm, the maximum thickness of the irregular shape of the wool is 1.3 mm. 1.3 mm thick titanium plate below, filling the mold with the soil to create a tolerance of 0.1 mm; But for titanium wins 3.2 meters below, shall tolerances down to ± 0.025 mm. Warming will reduce the thickness of titanium cutting edge cracks.
     Die should titanium plate aerospace investment castings having rigidity, the upper and lower guide post to maintain the exact relative positions of the mold. When the material thickness increase, such a requirement is more urgent. Less rigid process equipment will cause mold damage and cattle production sheet metal edge crack. Die cutting edge should be sharp, no uneven. Gap material mode of titanium, can be expected under aircaft investment ordinary copper mold with a gap, but the shear angle should be larger.
