説明
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.
主な機能
- 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
- ドローイングレビューとDFM合金、荷重方向、重要な寸法を確認し、その後 QForm シミュレーションを実行して金属流動と欠陥リスクを予測します。.
- デザインと製造ダイセットの数（例えば、ブロッカーダイとファイニッシャーダイ）は部品の複雑さに合わせて計画されており、ダイの形状は携帯型3Dスキャナーで確認されます。.
- 熱間鍛造600T～8,000Tの熱間鍛造プレスでの閉型成形により、部品の形状に沿った連続した粒状流が生成されます。.
- 熱処理T4溶液処理とT6人工老化は社内で実施され、合金および強度要件によって設定されたパラメータが使用されます。.
- CNC加工 そして仕上げ穴、スレッド、接合面は機械加工され、その後、必要に応じてバリ取り、振動仕上げ、ショットブラスト、または陽極酸化が行われます。.
- 検査と発送寸法、硬度、化学組成はCMM、硬度計、分光計を用いて確認され、ロットのトレーサビリティはIATF 16949に従って管理されています。.
よくある質問
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.
