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.
主な機能
- 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

よくある質問
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?
はい。Al Forge Techは主にOEMサプライヤーとして活動しており、エンジニアはコンセプトまたは図面段階で設計適合性評価(DFM)のフィードバックを提供できます。これには、薄い肋骨の調整、急な断面変更、およびラップやアンダーフィルを回避するために設計された角度の調整などが含まれます。QFormシミュレーションは金属流動を早期に予測し、その結果は当社による金型設計経験と比較されます。.
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.
