描述
Bicycle Forging E-12: Round-Head Arm-Type Aluminum Forging
Bicycle forging E-12 is an arm-type aluminum forging developed by Al Forge Tech (AFT) to the customer’s drawing. It has a round boss at one end and a tapering round arm, with a flat boss face that can be machined with a bore, spline or thread as a pivot or connection point. Arm-type forgings like this are common in bicycle cranks, operating arms, links and other load-transmitting arms.
The junction between boss and arm carries bending moment under load, and forging carries grain flow continuously from arm into boss, preserving material continuity better than machining from bar. After hot forging, AFT can heat treat, CNC-machine the boss holes and arm features, and anodize or shot-blast the part, delivering forged blanks or finished parts.
主要功能
- Round boss and tapering arm hot forged in one piece
- Boss machinable with bore, spline or thread as a pivot
- Continuous grain flow at the junction carries bending moment
- Delivered as forged blank, semi-finished or finished part

Bicycle Forging E-12 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。.
- 熱鍛造600T–8,000T 熱鍛造壓 Presses 的閉式成形技術創造出持續的晶粒流，並遵循零件的輪廓。.
- 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
Can arm-type forgings like E-12 be developed to my own design?
Yes. AFT works mainly as an OEM supplier, and E-12 is an arm-type forging developed to a customer’s drawing. Send a 3D model or 2D drawing and our engineers will evaluate arm length, boss size, section changes and alloy, plan dies and heat treatment, and suggest forging features such as draft angles and radii at the DFM stage.
Are there limits on arm length and boss proportion?
The longer the arm and the larger the boss, the more material must be gathered and the higher the forming force, which may require a preform stage to concentrate material into the boss first. AFT’s hot forging presses range from 600T to 8,000T, so the press is selected by part size, and QForm simulation confirms that the boss fills completely.
How does a forged aluminum Bicycle Forging E-12 compare with casting or machining from billet?
Forging shapes aluminum in the solid state under pressure, so the grain flow follows the part contour and the porosity and shrinkage common in castings are avoided. Compared with machining from solid billet, a near-net-shape forging removes less material and shortens machining time. For a Bicycle Forging E-12 under repeated loads, forging balances strength and weight; the final choice still depends on design loads and volume.
What information do you need to quote the Bicycle Forging E-12?
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 Bicycle Forging E-12 at the quotation stage. If the design is still conceptual, a sketch is enough to start a DFM discussion.
How are MOQ and lead time for the Bicycle Forging E-12 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 Bicycle Forging E-12.
