One end is a round bar that transitions smoothly into a wide flat paddle at the other end, with the section changing from round to flat along the arm. The flat end can be machined with mounting holes or used as a clamping or connecting face, as is common on bicycle operating levers, support arms and connectors.<\/p>\n<p>Machining a round-to-flat transition from bar removes a lot of material; forging presses the changing section directly, with grain flow turning smoothly into the flat end, combining good material yield with strength. After hot forging, AFT can heat treat, CNC-machine mounting holes and faces, and finish the part by anodizing or shot blasting.<\/p>\n<h3>\u4e3b\u306a\u6a5f\u80fd<\/h3>\n<ul>\n<li>Round section

ends in a round boss suited to a pivot or spline connection; E-13 ends in a wide flat paddle suited to mounting holes or a clamping face. Both are arm-type forgings developed to customer drawings, and the choice of shape depends on how the part is assembled and loaded.<\/p>\n<h3>How is dimensional consistency controlled on a forging with a changing section?<\/h3>\n<p>Material flow varies greatly through the transition zone and must be precisely controlled by the die. AFT confirms fill at each section with QForm during die design, checks first, middle and last pieces in every production lot, reworks the die when wear causes dimensional drift, and measures key sections on CMM.<\/p>\n<h3>How are MOQ and lead time for the Bicycle Forging E-13 determined?<\/h3>\n<p>MOQ and lead time depend on part size, number of die sets, alloy and machining scope, and are confirmed in the quotation after drawing review. The typical sequence is die development, forged samples, sample approval and then mass production.
