Aluminum Gearbox Housing Manufacturer in China for OEM Drive Systems
齿轮箱
China aluminum gearbox housing manufacturer for OEM RFQs needing A356-T6 gravity casting, machined bearing seats, sealing-face control, and export-ready supply.
Product Overview
This page targets gearbox housing sourcing intent from OEM buyers who need a China manufacturer able to control both casting structure and machining datum stability.
Bohua produces gravity-cast A356-T6 gearbox housings for reducer, transmission, and drive-system programs where bearing seat position, cover-face flatness, oil-seal interfaces, and rib stiffness affect assembly yield and service life.
Instead of treating the part as a generic shell, we review load path, wall thickness balance, machining allowance, and tooling direction before quotation.
Our workflow covers DFM, mold development, sample submission, CNC machining, dimensional inspection, and export packaging so global buyers can source cast-plus-machined gearbox housings from one supplier.
If your program requires an OEM export-ready source for reducer or transmission housings, send the drawing package, annual volume, machining scope, and inspection standard for a structured RFQ response.
