id=\"what-pressure-can-an-aluminum-cylinder-case-withstand\">What pressure can an aluminum cylinder case withstand?<\/h3>\n<p>Pressure capability depends on alloy, temper, wall thickness and housing design, so there is no single figure. For reference, AFT has impact extruded construction-machinery engine fuel filter housings and end caps with a design pressure range of 8\u201320 MPa. New projects must be validated against your design pressure, safety factor and test standard, and AFT can provide material and dimensional inspection data to support this.<\/p>\n<h3 id=\"how-are-the-hex-boss-and-threads-machined\">How are the hex boss and threads machined?<\/h3>\n<p>The hex boss can be formed to a near-net contour during impact extrusion or a subsequent forging step, then CNC-finished to the across-flats dimension. Threads, O-ring grooves and sealing faces at the open end are turned on lathes. AFT completes forming, heat treatment and machining in one facility and checks housings on a fluorescent penetrant inspection line to reduce leak risk in pressure parts.<\/p>\n<h3 id=\"how-do-you-keep-the-aluminum-cylinder-case-consistent-from-lot-to-lot\">How do you keep the Aluminum Cylinder Case 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 Aluminum Cylinder Case stable across lots.<\/p>\n<h3 id=\"what-information-do-you-need-to-quote-the-aluminum-cylinder-case\">What information do you need to quote the Aluminum Cylinder Case?<\/h3>\n<p>Please send a 3D model and 2D drawing, alloy grade and temper, critical tolerances, surface finish requirements, estimated annual volume and target delivery date. Complete data lets our engineers judge forging feasibility, the number of die sets and the machining scope for the Aluminum Cylinder Case at the quotation stage. If the design is still conceptual, a sketch is enough to start a DFM discussion.<\/p>\n<h3 id=\"can-al-forge-tech-supply-the-aluminum-cylinder-case-from-forging-through-machining\">Can Al Forge Tech supply the Aluminum Cylinder Case 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 Aluminum Cylinder Case can be delivered as a forged blank, semi-finished or fully machined part.<\/p>\n<h2 id=\"request-a-quote-for-the-aluminum-cylinder-case\">Request a Quote for the Aluminum Cylinder Case<\/h2>\n<p>Developing a new Aluminum Cylinder Case or converting an existing part to aluminum forging?
