Impact Extrusion Tube-4
描述
Aluminum Long Impact Extrusion Tube: Long Thin-Wall Tube with Stepped Sections
The aluminum long impact extrusion tube is a longer thin-walled round tube with a diameter step along its body. Al Forge Tech (AFT) cold impact extrudes the tube body and then machines the ends and stepped sections to drawing. Long tubes like this are common as shock absorber outer tubes, hydraulic or pneumatic cylinder barrels, telescopic outer tubes and long protective sleeves.
Long tubes demand even wall thickness and good straightness. In impact extrusion, metal flow is governed by the gap between punch and die, giving a stable wall-thickness distribution. AFT plans the forming sequence by length and wall thickness, then straightens after heat treatment, faces the ends and inspects dimensions, with anodizing available for wear and corrosion resistance.
主要功能
- Long thin-wall body cold formed with stable wall thickness
- Stepped outer diameters designed to suit mating parts
- Straightening and straightness inspection after heat treatment
- Anodizing or hard anodizing for wear resistance

Aluminum Long Impact Extrusion Tube Manufacturing Process
- 繪圖評估與 DFM我們確認合金、載荷方向和關鍵尺寸，然後執行 QForm 模擬，以預測金屬流動和缺陷風險。.
- 設計與製造銑刀組數（例如，阻斷刀和完成刀）視零件的複雜程度而定，銑刀輪廓則使用便攜式3D掃描儀進行檢查。.
- Cold forging: impact extrusion on 260T–2,500T presses, suited to thin-walled, tubular and dimensionally repeatable parts.
- 熱處理T4 溶液處理和 T6 人工老化處理均在廠內進行，參數由合金和強度要求設定。.
- CNC加工 以及完成孔、螺紋和接合面均經過機械加工，然後根據需要進行拋光、振動拋光、噴丸或陽極氧化處理。.
- 檢查與運輸尺寸、硬度及化學成分均通過 CMM、硬度測試儀及分光光度儀進行驗證，且所有批次的產品均遵照 IATF 16949 的標準進行追蹤。.
常見問題
How is straightness controlled on a long impact extruded tube?
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.
How does impact extruding a long tube differ from a short one?
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’s cold forging presses cover 260T–2,500T, 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.
Can the Aluminum Long Impact Extrusion Tube be anodized or given other surface finishes?
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.
How are MOQ and lead time for the Aluminum Long Impact Extrusion Tube determined?
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.
Can you assess forging feasibility while the Aluminum Long Impact Extrusion Tube is still in design?
是的。Al Forge Tech 主要作為 OEM 供應商提供服務，我們的工程師可以在構思或繪圖階段就設計的可生產性（DFM）提供意見，例如調整薄邊緣、急切的切面變化或設計角度，以避免殘料和未填充區域。QForm 模擬能及早預測金屬流動，並與我們已有的模具設計經驗進行交叉核對。.
