Compact calipers like this are used as halves of two-piece calipers or in mechanical and single-piston caliper designs.<\/p>\n<p>The caliper body must stay dimensionally stable under braking. Forging keeps grain flow continuous between boss and body and gives a dense structure that is less prone to leaks after the piston bore is machined. After hot forging, Al Forge Tech (AFT) applies in-house T6 heat treatment, CNC-machines the bore, fluid passages and mounting holes, and inspects with fluorescent penetrant and CMM.<\/p>\n<h3>Key Features<\/h3>\n<ul>\n<li>Compact body and cylindrical boss forged in one piece<\/li>\n<li>Suited to two-piece caliper halves or single-piston designs<\/li>\n<li>Dense forged structure reduces leak risk after bore machining<\/li>\n<li>Fluorescent penetrant and CMM inspection<\/li>\n<\/ul>\n<h2>Forged Aluminum Bicycle Brake Caliper (Single Boss) Specifications and Manufacturing Capability<\/h2>\n<div class=\"table-container\">\n<table class=\"table table-bordered table-striped\">\n<thead>\n<tr>\n<th>Item<\/th>\n<th>Details<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Product category<\/td>\n<td>Aluminum Forging Bicycle Parts<\/td>\n<\/tr>\n<tr>\n<td>Application<\/td>\n<td>Bicycle disc brake calipers (two-piece halves, single-piston or mechanical designs)<\/td>\n<\/tr>\n<tr>\n<td>Primary process<\/td>\n<td>Closed-die hot forging (hot forging presses 600T\u20138,000T)<\/td>\n<\/tr>\n<tr>\n<td>Material<\/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>Heat treatment<\/td>\n<td>In-house T4 solution treatment (8 units) and T6 artificial aging (7 units), set by alloy and strength requirement<\/td>\n<\/tr>\n<tr>\n<td>Secondary machining<\/td>\n<td>CNC machining (52 machining centers, 30 lathes), deburring, vibratory finishing<\/td>\n<\/tr>\n<tr>\n<td>Surface finish<\/td>\n<td>Anodizing (including hard anodizing), shot blasting, e-coating or painting, as required<\/td>\n<\/tr>\n<tr>\n<td>Inspection<\/td>\n<td>Zeiss CMM (4 units), hardness testers, spectrometer, fluorescent penetrant inspection line<\/td>\n<\/tr>\n<tr>\n<td>Dimensions and tolerances<\/td>\n<td>Per customer 2D\/3D drawings<\/td>\n<\/tr>\n<tr>\n<td>Quality system<\/td>\n<td>IATF 16949:2016, ISO 14001:2015<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h2>Forged Aluminum Bicycle Brake Caliper (Single Boss) Manufacturing Process<\/h2>\n<ol>\n<li><strong>Drawing review and DFM<\/strong>: we confirm alloy, load direction and critical dimensions, then run QForm simulation to predict metal flow and defect risk.<\/li>\n<li><strong>Die design and manufacturing<\/strong>: the number of die sets (for example, blocker and finisher dies) is planned around part complexity, and die contours are checked with a portable 3D scanner.<\/li>\n<li><strong><a href=\"https:\/\/aft-forge.com\/forging-service\/hot-forging-service\/\">Hot forging<\/a><\/strong>: closed-die forming on 600T\u20138,000T hot forging presses creates a continuous grain flow that follows the part contour.<\/li>\n<li><strong>Heat treatment<\/strong>: T4 solution treatment and T6 artificial aging are performed in-house, with parameters set by alloy and strength requirement.<\/li>\n<li><strong><a href=\"https:\/\/aft-forge.com\/forging-service\/aluminum-cnc-machining-services\/\">CNC machining<\/a> and finishing<\/strong>: holes, threads and mating surfaces are machined, followed by deburring, vibratory finishing, shot blasting or anodizing as required.<\/li>\n<li><strong>Inspection and shipment<\/strong>: dimensions, hardness and chemical composition are verified with CMM, hardness testers and a spectrometer, with lot traceability kept under IATF 16949.<\/li>\n<\/ol>\n<h2>FAQ<\/h2>\n<h3>How do two-piece and monobloc calipers differ in forging?<\/h3>\n<p>A two-piece caliper is assembled from two halves, each simpler in shape, formed with fewer dies and easier to machine into bores and passages. A monobloc caliper is machined from a single forging, with a complex shape requiring multiple die sets but higher stiffness. AFT has production experience with both and can recommend based on the brand&#8217;s performance and cost targets.<\/p>\n<h3>How are piston bores kept leak-free?<\/h3>\n<p>Leaks usually come from internal porosity or surface defects on machined faces. Forged aluminum is dense, lowering the risk of internal porosity, and AFT inspects machined parts for surface defects on its fluorescent penetrant line and cleans fluid passages on its ultrasonic washing line. Bore size and surface roughness are measured with CMM and a surface roughness tester.<\/p>\n<h3>Can you assess forging feasibility while the Forged Aluminum Bicycle Brake Caliper (Single Boss) is still in design?<\/h3>\n<p>Yes. Al Forge Tech works mainly as an OEM supplier, and our engineers can give design-for-manufacturability (DFM) feedback at the concept or drawing stage, such as adjusting thin ribs, abrupt section changes or draft angles to avoid laps and underfill. QForm simulation predicts metal flow early, and the results are cross-checked against our die design experience.<\/p>\n<h3>Can the Forged Aluminum Bicycle Brake Caliper (Single Boss) be anodized or given other surface finishes?<\/h3>\n<p>Yes. Al Forge Tech offers anodizing (including hard anodizing), shot blasting, vibratory finishing, e-coating and painting, plus pickling and ultrasonic washing lines to clean parts after machining. Please note the finish type and film thickness on the drawing so machining allowances and cosmetic standards for the Forged Aluminum Bicycle Brake Caliper (Single Boss) can be evaluated together.<\/p>\n<h3>Is heat treatment for the Forged Aluminum Bicycle Brake Caliper (Single Boss) done in-house?<\/h3>\n<p>Yes. Al Forge Tech operates 8 T4 solution treatment units and 7 T6 artificial aging units on site, so the Forged Aluminum Bicycle Brake Caliper (Single Boss) can be solution treated, quenched and aged in the same facility before machining and inspection. Keeping heat treatment in-house removes inter-plant transport, reduces lead-time risk and keeps lot traceability within one quality system. Parameters are set according to the alloy grade and your specification.<\/p>\n<h2>Request a Quote for the Forged Aluminum Bicycle Brake Caliper (Single Boss)<\/h2>\n<p>Developing a new Forged Aluminum Bicycle Brake Caliper (Single Boss) or converting an existing part to aluminum forging?
