Suspension Component
描述
Aluminum Bicycle Suspension Component: Damper Rod with Integral End Seat
This aluminum bicycle suspension component is an internal rod for a suspension fork or rear shock. It has a long slender solid or hollow shaft with a larger-diameter polygonal end seat at one end, which can be threaded or used as a mounting base for a piston or valve seat. Rod and end seat are formed in one piece, reducing the loosening and fit errors of threaded assemblies.
Turning a slender rod with a large end seat from bar would start from bar of the seat diameter and remove most of the shaft material. Forging gathers material into the end seat while the shaft keeps the stock diameter, saving material and turning time. Al Forge Tech (AFT) evaluates cold or hot forming by seat volume and rod length, then finish-turns the shaft diameter and threads.
主要功能
- Slender shaft and large end seat formed in one piece
- Upset-forged end seat saves bar stock and turning time
- Shaft OD, threads and seat finish-turned
- Anodizing or hard anodizing available

Aluminum Bicycle Suspension Component 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: cold forming 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
What is upsetting, and why does it suit a rod end seat?
Upsetting presses bar locally so material gathers at one end to form a larger-diameter head or seat. For a slender rod with a large end seat, it allows the part to be made from bar close to the shaft diameter instead of turning the whole part from thick bar of the seat diameter, cutting material use and machining time while grain flow follows the seat contour.
How is dimensional accuracy ensured on internal suspension parts?
Internal suspension parts mate with pistons, shims and seals, so shaft diameter and concentricity are critical. After heat treatment, AFT finish-turns the shaft and end seat, measures diameter, concentricity and threads with CMM and gauges, and keeps inspection records under IATF 16949.
Can you assess forging feasibility while the Aluminum Bicycle Suspension Component 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。.
How do you keep the Aluminum Bicycle Suspension Component consistent from lot to lot?
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 Bicycle Suspension Component stable across lots.
How are MOQ and lead time for the Aluminum Bicycle Suspension Component 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 Bicycle Suspension Component.
