ABOUT AOYIDA
Brake actuation, made since 1995.
AOYIDA (奥毅达) is the product brand of AODA Machinery, the Wenling manufacturer registered as Wenlingshi AODA Machinery Co., Ltd. (温岭市奥达机械有限公司). Brake components have been our only business since 1995; the present company was registered in 2003 when production moved to the current Wenling site. Since then the focus has not changed: brake boosters, hydraulic boosters, master cylinders and clutch-assist components for global aftermarket programs.
THE FACTORY AND THE BRAND
Our own production line
AOYIDA (奥毅达) is the name on the box; AODA Machinery (奥达机械有限公司) is the Wenling factory that builds what's inside. On the parts we make there is no trading layer in between — the same team that develops, matches and packs them is the one that quotes them.
AOYIDA is also the export side. When an order needs other automotive parts we do not build ourselves, we can buy them in, consolidate them with your own parts and ship one container under one contract and one set of export documents.

View public report ↗One sourcing system across four product families
AOYIDA organizes global catalog records, a North America Buyers Guide and direct factory review into one product workflow.
Four product families
Product family, reference identity and vehicle application stay separate so similar-looking parts are not treated as interchangeable.
Vacuum boosters
Brake-assist units organized by application and reference number.
Brake master cylinders
Master-cylinder programs reviewed against vehicle and number evidence.
Hydraulic boosters
Hydraulic brake-assist products kept distinct from vacuum systems.
Clutch boosters
A separate product family for clutch-assist sourcing.
Bench testing before packing
Not a leak check alone. Each unit runs a four-stage characteristic test — idle seal, seal below the boost point, seal above the boost point, and the full input-to-output force curve. The tester judges pass or fail against preset limits and saves the result with the product code and a timestamp.
- Stages per unit
- 4
- three seal tests + characteristic curve
- Coverage
- Every unit
- not a batch sample
- Judgement
- Automatic
- tester decides against preset limits
- Record
- Saved
- product code and timestamp, every test
Vacuum booster test station. Wenling plant. Every unit off the line is fixtured and run — no bench sampling.
Master cylinder seal test. Dedicated bench, hand-loaded, unit by unit.
MASTER CYLINDERS
The same discipline on the cylinder line
Master cylinder bodies are pressure- and vacuum-sealed on a dedicated bench. The leak threshold is preset on the station controller, the live reading is displayed against it, and every unit is loaded and judged one at a time.
Test parameters, acceptance limits and work instructions are controlled documents. We share them under a signed quality agreement, not on a public page.
Contract manufacturing
A large share of this factory's output ships under customer brands rather than our own. Programs are accepted on all four lines, and can open from a sample, a purchase link, or a part number — drawings are welcome but not a prerequisite.
- 01
Sample, link or part number
Send a physical sample, a purchase link we buy from ourselves, or the part number alone. If you hold 2D/3D drawings, we work from those instead.
- 02
Reverse engineering and drawings
The sample is measured here and the drawings are produced in-house. No engineering resource is required on the customer side.
- 03
First article before tooling
A first article sample is submitted for customer approval. Tooling is cut after approval, not before.
- 04
Customer part number and packaging
Customer part number, label artwork and carton — or neutral packaging. Produced on the same line and to the same process controls as our own brand.
Buying in the rest of your order
AODA Machinery builds the brake actuation parts. AOYIDA is the export side, so when an order needs other automotive parts we do not build, we buy them in against your list, load them in the same container as our own parts, and ship under one contract.
- What we source
- Automotive parts only. Other categories are outside what this factory takes on.
- Export documents
- Commercial invoice, packing list, bill of lading and certificate of origin — one set covering the sourced parts and ours.
- Incoming inspection
- Sampling inspection against the standard you set.
