Its arc-shaped body follows the outer edge of the brake disc, with several piston-bore bosses arranged along the arc and radial mounting ears at both ends. The arc shape fits large-diameter discs, and the multi-piston layout spreads clamping pressure so the pads load evenly.<\/p>\n<p>With several bore bosses along a slender arc, material must fill both the body and every boss during forging. Al Forge Tech (AFT) plans multiple forging stages and die sets for the shape (a monobloc caliper typically needs three die sets), confirms fill with QForm simulation, closed-die hot forges the body and completes T6 heat treatment in-house, then machines piston bores, fluid passages and mounting holes on 4.5-axis CNC.

Otherwise the body ends or bosses can underfill, or laps can form at the boss roots. AFT plans billet shape and preforms with QForm simulation, forms the part progressively with blocker, intermediate and finisher dies, and checks the form on first, middle and last pieces.<\/p>\n<h3>Which aluminum alloys are used for forged calipers?<\/h3>\n<p>Caliper material must balance strength, stiffness and sealing integrity after machining. 6061-T6 offers balanced machinability and corrosion resistance and is widely used; 7xxx alloys provide higher strength for high-load racing or performance calipers but need anodizing for corrosion resistance. AFT works with 2xxx, 6xxx and 7xxx alloys, and the final choice follows the customer&#8217;s performance targets and test standards.<\/p>\n<h3>Can you assess forging feasibility while the Forged Aluminum Automotive Multi-Piston Brake Caliper is still in design?<\/h3>\n<p>\u306f\u3044\u3002Al Forge Tech\u306f\u4e3b\u306bOEM\u30b5\u30d7\u30e9\u30a4\u30e4\u30fc\u3068\u3057\u3066\u6d3b\u52d5\u3057\u3066\u304a\u308a\u3001\u30a8\u30f3\u30b8\u30cb\u30a2\u306f\u30b3\u30f3\u30bb\u30d7\u30c8\u307e\u305f\u306f\u56f3\u9762\u6bb5\u968e\u3067\u8a2d\u8a08\u9069\u5408\u6027\u8a55\u4fa1(DFM)\u306e\u30d5\u30a3\u30fc\u30c9\u30d0\u30c3\u30af\u3092\u63d0\u4f9b\u3067\u304d\u307e\u3059\u3002\u3053\u308c\u306b\u306f\u3001\u8584\u3044\u808b\u9aa8\u306e\u8abf\u6574\u3001\u6025\u306a\u65ad\u9762\u5909\u66f4\u3001\u304a\u3088\u3073\u30e9\u30c3\u30d7\u3084\u30a2\u30f3\u30c0\u30fc\u30d5\u30a3\u30eb\u3092\u56de\u907f\u3059\u308b\u305f\u3081\u306b\u8a2d\u8a08\u3055\u308c\u305f\u89d2\u5ea6\u306e\u8abf\u6574\u306a\u3069\u304c\u542b\u307e\u308c\u307e\u3059\u3002QForm\u30b7\u30df\u30e5\u30ec\u30fc\u30b7\u30e7\u30f3\u306f\u91d1\u5c5e\u6d41\u52d5\u3092\u65e9\u671f\u306b\u4e88\u6e2c\u3057\u3001\u305d\u306e\u7d50\u679c\u306f\u5f53\u793e\u306b\u3088\u308b\u91d1\u578b\u8a2d\u8a08\u7d4c\u9a13\u3068\u6bd4\u8f03\u3055\u308c\u307e\u3059\u3002.<\/p>\n<h3>How do you keep the Forged Aluminum Automotive Multi-Piston Brake Caliper consistent from lot to lot?<\/h3>\n<p>Al Forge Tech runs incoming (IQC), in-process (IPQC) and final (FQC) inspection under IATF 16949:2016, supported by 4 Zeiss CMMs, hardness testers, a spectrometer and a fluorescent penetrant inspection line.
