left;\">How is straightness controlled on a long impact extruded tube?<\/h3>\n<p style=\"text-align: left;\">Straightness is affected by forming, quenching during heat treatment and machining. AFT keeps punch and die concentric in the tool design to limit run-out during forming, straightens after heat treatment where needed, and measures straightness and runout during turning and inspection. Please state the tolerance on the drawing so we can judge whether extra straightening or finishing steps are required.<\/p>\n<h3 style=\"text-align: left;\">How does impact extruding a long tube differ from a short one?<\/h3>\n<p style=\"text-align: left;\">A long tube needs a longer stroke and higher forming force, and the thinner and longer the wall, the more carefully metal flow must be controlled to avoid uneven walls or a ragged rim. AFT&#8217;s cold forging presses cover 260T\u20132,500T, and we select the press and decide whether staged forming or trimming of the open end is needed based on diameter, wall thickness and length.<\/p>\n<h3 style=\"text-align: left;\">Can the Aluminum Long Impact Extrusion Tube be anodized or given other surface finishes?<\/h3>\n<p style=\"text-align: left;\">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 Aluminum Long Impact Extrusion Tube can be evaluated together.<\/p>\n<h3 style=\"text-align: left;\">How are MOQ and lead time for the Aluminum Long Impact Extrusion Tube determined?<\/h3>\n<p style=\"text-align: left;\">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 Aluminum Long Impact Extrusion Tube.<\/p>\n<h3 style=\"text-align: left;\">Can you assess forging feasibility while the Aluminum Long Impact Extrusion Tube is still in design?<\/h3>\n<p style=\"text-align: left;\">\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<h2 style=\"text-align: left;\">Request a Quote for the Aluminum Long Impact Extrusion Tube<\/h2>\n<p style=\"text-align: left;\">Developing a new Aluminum Long Impact Extrusion Tube or converting an existing part to aluminum forging?
