The box-shaped body carries bosses and mounting ears, and the barrel extends diagonally upward from it as a mounting section for a hose, hydraulic cylinder or linkage. Body and barrel are forged in one piece with no separately welded or threaded extension.<\/p>\n<p>Where the barrel meets the body the section changes abruptly, and material must flow smoothly into the slender barrel during forging. Al Forge Tech (AFT) plans preform and finisher stages for closed-die hot forging so grain flow runs continuously from body into barrel. After heat treatment, the barrel bore, fluid passages and mounting holes are CNC-machined, and barrel angle and hole positions are verified on CMM.<\/p>\n<h3>\u4e3b\u8981\u529f\u80fd<\/h3>\n<ul>\n<li>Box-shaped body and angled barrel forged in one piece<\/li>\n<li>No welded or threaded extension interface<\/li>\n<li>Barrel bore, fluid passages and mounting holes CNC-machined<\/li>\n<li>Barrel angle and hole positions verified on CMM<\/li>\n<\/ul>\n<h2>Forged Aluminum Bicycle Brake Caliper (Extended Barrel) Specifications and Manufacturing Capability<\/h2>\n<div class=\"table-container\">\n<table class=\"table table-bordered table-striped\">\n<thead>\n<tr>\n<th>\u5546\u54c1<\/th>\n<th>\u8a73\u7d30<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>\u7522\u54c1\u985e\u5225<\/td>\n<td>Aluminum Forging Bicycle Parts<\/td>\n<\/tr>\n<tr>\n<td>\u7533\u8acb<\/td>\n<td>Bicycle hydraulic brake bodies (to brand design)<\/td>\n<\/tr>\n<tr>\n<td>\u4e3b\u8981\u904e\u7a0b<\/td>\n<td>\u9589\u5f0f\u71b1\u935b\u9020\uff08\u71b1\u935b\u9020\u58d3\u6a5f 600T\u20138,000T\uff09<\/td>\n<\/tr>\n<tr>\n<td>\u6750\u8cea<\/td>\n<td>Selected to customer specification; 2xxx, 5xxx, 6xxx and 7xxx series aluminum alloys available (e.g. 2014, 6061, 6082, 7075)<\/td>\n<\/tr>\n<tr>\n<td>\u71b1\u8655\u7406<\/td>\n<td>\u6839\u64da\u5408\u91d1\u8207\u5f37\u5ea6\u8981\u6c42\u800c\u63d0\u4f9b\u7684\u5167\u90e8 T4 \u8655\u7406\u65b9\u6848\uff088 \u5957\uff09\u53ca T6 \u4eba\u5de5\u8001\u5316\u8655\u7406\u65b9\u6848\uff087 \u5957\uff09<\/td>\n<\/tr>\n<tr>\n<td>\u4e8c\u6b21\u52a0\u5de5<\/td>\n<td>CNC \u52a0\u5de5\uff0852 \u53f0\u52a0\u5de5\u4e2d\u5fc3\u300130 \u53f0\u9291\u5e8a\uff09\u3001\u9291\u524a\u3001\u632f\u52d5\u78e8\u524a<\/td>\n<\/tr>\n<tr>\n<td>\u8868\u9762\u8655\u7406<\/td>\n<td>\u6309\u8981\u6c42\u9032\u884c\u967d\u6975\u6c27\u5316\uff08\u5305\u62ec\u786c\u967d\u6975\u6c27\u5316\uff09\u3001\u5674\u5c04\u7c89\u788e\u3001\u96fb\u5b50\u5857\u5c64\u6216\u5857\u6f06\u3002<\/td>\n<\/tr>\n<tr>\n<td>\u6aa2\u67e5<\/td>\n<td>Zeiss CMM (4 units), hardness testers, spectrometer, fluorescent penetrant inspection line<\/td>\n<\/tr>\n<tr>\n<td>\u5c3a\u5bf8\u8207\u516c\u5dee<\/td>\n<td>\u6309\u5ba2\u6236\u63d0\u4f9b2D\/3D\u5716\u7d19<\/td>\n<\/tr>\n<tr>\n<td>\u54c1\u8cea\u7ba1\u7406\u7cfb\u7d71<\/td>\n<td>IATF 16949:2016\u3001ISO 14001:2015<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h2>Forged Aluminum Bicycle Brake Caliper (Extended Barrel) Manufacturing Process<\/h2>\n<ol>\n<li><strong>\u7e6a\u5716\u8a55\u4f30\u8207 DFM<\/strong>\u6211\u5011\u78ba\u8a8d\u5408\u91d1\u3001\u8f09\u8377\u65b9\u5411\u548c\u95dc\u9375\u5c3a\u5bf8\uff0c\u7136\u5f8c\u57f7\u884c QForm \u6a21\u64ec\uff0c\u4ee5\u9810\u6e2c\u91d1\u5c6c\u6d41\u52d5\u548c\u7f3a\u9677\u98a8\u96aa\u3002.<\/li>\n<li><strong>\u8a2d\u8a08\u8207\u88fd\u9020<\/strong>\u9291\u5200\u7d44\u6578\uff08\u4f8b\u5982\uff0c\u963b\u65b7\u5200\u548c\u5b8c\u6210\u5200\uff09\u8996\u96f6\u4ef6\u7684\u8907\u96dc\u7a0b\u5ea6\u800c\u5b9a\uff0c\u9291\u5200\u8f2a\u5ed3\u5247\u4f7f\u7528\u4fbf\u651c\u5f0f3D\u6383\u63cf\u5100\u9032\u884c\u6aa2\u67e5\u3002.<\/li>\n<li><strong><a href=\"https:\/\/aft-forge.com\/zh\/forging-service\/hot-forging-service\/\">\u71b1\u935b\u9020<\/a><\/strong>600T\u20138,000T \u71b1\u935b\u9020\u58d3 Presses \u7684\u9589\u5f0f\u6210\u5f62\u6280\u8853\u5275\u9020\u51fa\u6301\u7e8c\u7684\u6676\u7c92\u6d41\uff0c\u4e26\u9075\u5faa\u96f6\u4ef6\u7684\u8f2a\u5ed3\u3002.<\/li>\n<li><strong>\u71b1\u8655\u7406<\/strong>T4 \u6eb6\u6db2\u8655\u7406\u548c T6 \u4eba\u5de5\u8001\u5316\u8655\u7406\u5747\u5728\u5ee0\u5167\u9032\u884c\uff0c\u53c3\u6578\u7531\u5408\u91d1\u548c\u5f37\u5ea6\u8981\u6c42\u8a2d\u5b9a\u3002.<\/li>\n<li><strong><a href=\"https:\/\/aft-forge.com\/zh\/forging-service\/aluminum-cnc-machining-services\/\">CNC\u52a0\u5de5<\/a> \u4ee5\u53ca\u5b8c\u6210<\/strong>\u5b54\u3001\u87ba\u7d0b\u548c\u63a5\u5408\u9762\u5747\u7d93\u904e\u6a5f\u68b0\u52a0\u5de5\uff0c\u7136\u5f8c\u6839\u64da\u9700\u8981\u9032\u884c\u62cb\u5149\u3001\u632f\u52d5\u62cb\u5149\u3001\u5674\u4e38\u6216\u967d\u6975\u6c27\u5316\u8655\u7406\u3002.<\/li>\n<li><strong>\u6aa2\u67e5\u8207\u904b\u8f38<\/strong>\u5c3a\u5bf8\u3001\u786c\u5ea6\u53ca\u5316\u5b78\u6210\u5206\u5747\u901a\u904e CMM\u3001\u786c\u5ea6\u6e2c\u8a66\u5100\u53ca\u5206\u5149\u5149\u5ea6\u5100\u9032\u884c\u9a57\u8b49\uff0c\u4e14\u6240\u6709\u6279\u6b21\u7684\u7522\u54c1\u5747\u9075\u7167 IATF 16949 \u7684\u6a19\u6e96\u9032\u884c\u8ffd\u8e64\u3002.<\/li>\n<\/ol>\n<h2>\u5e38\u898b\u554f\u984c<\/h2>\n<h3>What is the benefit of forging the barrel in one piece with the body?<\/h3>\n<p>If the barrel were welded or threaded onto the body, the joint could become a hydraulic leak path or weak point and would add assembly steps. One-piece forging forms barrel and body from the same material with continuous grain flow and no joint, and fluid passages can be machined straight through one part, reducing leak risk.<\/p>\n<h3>How are forging defects avoided where the slender barrel meets the body?<\/h3>\n<p>Abrupt section changes can obstruct flow and cause underfill or laps. AFT uses QForm to simulate how material flows into the barrel, designs a preform so enough material reaches the barrel first, then completes the body detail in the finisher die, checking the junction on first, middle and last pieces.<\/p>\n<h3>How do you keep the Forged Aluminum Bicycle Brake Caliper (Extended Barrel) 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. First, middle and last pieces of every lot are checked against the die; when wear causes dimensional drift, the die is reworked to keep the Forged Aluminum Bicycle Brake Caliper (Extended Barrel) stable across lots.<\/p>\n<h3>Can Al Forge Tech supply the Forged Aluminum Bicycle Brake Caliper (Extended Barrel) from forging through machining?<\/h3>\n<p>Yes. Forging, heat treatment, CNC machining, surface finishing and inspection are integrated in one facility: 52 CNC machining centers (40 four-axis and 12 4.5-axis), 30 lathes (14 with robotic loading), plus broaching, burnishing and centerless grinding. The Forged Aluminum Bicycle Brake Caliper (Extended Barrel) can be delivered as a forged blank, semi-finished or fully machined part.<\/p>\n<h3>How are MOQ and lead time for the Forged Aluminum Bicycle Brake Caliper (Extended Barrel) 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. Sharing your annual volume and call-off schedule helps us plan dies and capacity for the Forged Aluminum Bicycle Brake Caliper (Extended Barrel).<\/p>\n<h2>Request a Quote for the Forged Aluminum Bicycle Brake Caliper (Extended Barrel)<\/h2>\n<p>Developing a new Forged Aluminum Bicycle Brake Caliper (Extended Barrel) or converting an existing part to aluminum forging?
