Transmission Casing
描述
Forged Aluminum Transmission Casing: Heavy-Motorcycle Drivetrain Housing
The forged aluminum transmission casing is a housing forging for a heavy-motorcycle drivetrain. It is an oval shallow shell with a round bearing-seat boss, a square mounting boss and several bolt bosses inside, and a sealing flange around the rim that mates with the engine case. The casing supports bearings, holds gear positions and protects internal mechanisms.
A forged casing is denser than a cast one, so bearing seats and sealing faces are less prone to porosity and oil seepage after machining, and walls can be thinner for the same stiffness. Al Forge Tech (AFT) closed-die hot forges the shell and internal bosses, applies in-house T6 heat treatment, machines bearing bores, sealing faces and bolt holes on 4.5-axis CNC, and verifies bearing-bore position and sealing-face flatness on CMM.
主要功能
- Shallow shell, internal bearing seat and mounting bosses forged in one piece
- Dense structure resists oil seepage after sealing-face machining
- Bearing bores and sealing faces on 4.5-axis CNC
- Bearing-bore position and sealing-face flatness measured on CMM

Forged Aluminum Transmission Casing 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
Why forge a transmission casing rather than cast it?
Casting can create complex internal cavities, but internal porosity may be exposed when bearing seats and sealing faces are machined, causing oil seepage or reduced strength. A forged casing is denser and stronger, allowing thinner walls for the same stiffness and lower weight. For housings that are mainly shallow shells with bosses, forging balances quality and weight; very deep or highly complex cavities need case-by-case evaluation.
How is sealing-face flatness ensured?
Sealing-face flatness determines whether the joint to the engine case seeps oil. AFT machines the sealing face only after T6 heat treatment so heat-treatment distortion does not affect final flatness, supports the casing with dedicated fixtures to limit machining distortion, and measures flatness and bearing-bore position on Zeiss CMM with records retained.
Is heat treatment for the Forged Aluminum Transmission Casing done in-house?
Yes. Al Forge Tech operates 8 T4 solution treatment units and 7 T6 artificial aging units on site, so the Forged Aluminum Transmission Casing can be solution treated, quenched and aged in the same facility before machining and inspection. Keeping heat treatment in-house removes inter-plant transport, reduces lead-time risk and keeps lot traceability within one quality system. Parameters are set according to the alloy grade and your specification.
Can you assess forging feasibility while the Forged Aluminum Transmission Casing 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。.
Can Al Forge Tech supply the Forged Aluminum Transmission Casing from forging through machining?
Yes. Forging, heat treatment, CNC machining, surface finishing and inspection are integrated in one facility: 52 CNC machining centers (40 four-axis and 12 4.5-axis), 30 lathes (14 with robotic loading), plus broaching, burnishing and centerless grinding. The Forged Aluminum Transmission Casing can be delivered as a forged blank, semi-finished or fully machined part.
