Deep red photo selection method blanking die and die thermal insulation and electric heating to an aluminum plastic brittle transition temperature above

Pure eight key pieces often pass deep red 38mm diameter used in the manufacture of thin-walled tubes of 45mm length, blanking round billet diameter 13omm. To reduce cracking tendencies, aluminum and aluminum deep drawing process will be a key piece stamping tools plastic is heated to a brittle transition temperature. To reduce the impact and  Tungsten copper alloy  and delamination of the key blank blanking die was modified. Polishing the flat punch with a rounded "V"-shaped concave surface, the "V"-type concave. Aluminum blade to shear loads. Two deep red photo selection method blanking die and die thermal insulation and electric heating to an  sandblasted tungsten target  brittle transition temperature. With this tool on the flywheel screw press can be easily cleaned without generating cracks round billet and the blanking operation and less laborious. Pat sector found in a platinum sheet manufacturing, particularly during cold rolling, the occurrence of the event that the incorrect heat treatment of any form of recrystallized material will be suitable for deep drawing.
