Allied Machinery Co., Ltd.
杭州联德精密机械股份有限公司
Allied Machinery, a Hangzhou maker of precision castings and machined parts, builds components for agricultural machinery to customer drawings. Its agriculture catalogue shows housing frames, an end housing, a left cam, brackets, a mounting frame and a main reducer housing. Allied covers development, casting, precision machining and inspection, including X-ray and coordinate measurement. Bring a drawing and the supply stage you want, from casting blank to machined part, and plan the first article and repeat deliveries around it.
Agricultural parts Allied makes, and how to specify them
Allied's agriculture page lists components, not farm machines. To quote a housing or frame, Allied needs the part's drawing and revision; a tractor brand or a photo is not enough. Two different parts share the name housing frame, so each needs its own drawing. State whether you want a casting blank, a machined part, an assembly or a full development programme. Finished farm components from other suppliers, such as chains, tracks and orbital motors, sit in our parts and attachments category.
[3][9][10]| Catalogue part | What to put on the enquiry |
|---|---|
| Housing frame and mounting frame | Part and drawing revision, mounting datums, load case and the assembly it mates with, plus material and whether it is welded. |
| End housing and housing | Bore relationships, sealing faces, bolt patterns and the machining state you want delivered. |
| Main reducer housing | Allied lists the housing itself. If you also need gears, shafts or assembly, say so and give ratio, lubricant and torque requirements. |
| Left cam and bracket | Geometry, interface, operating loads and inspection needs for your part. |
Company identity and production sites
Allied's English profile gives 2001 as its founding year. A September 2026 registration-change notice filed on the Shanghai Stock Exchange names 杭州联德精密机械股份有限公司, gives its founding date as 12 February 2001, and lists a Hangzhou address that matches the street and number in the website footer. The notice concerns a change in registered capital.
Allied runs several production bases, so casting, machining and shipping for one programme may happen at different sites. Name in the purchase order the contracting company, the sites that will make and inspect your parts, and who is responsible for changes and defects. For volume, ask for a production plan for your part; the group's headcount and floor area describe the whole business.
[1][2][8]From drawing to approved first article
Allied describes planning, design, development and trial production. Planning takes in customer standards, casting and machining processes, equipment, tooling, inspection resources and PPAP documentation. Agree early which approval documents and level your part needs. For casting tolerances and first-article checks on farm parts, our drawing-based sourcing guide sets out what to agree with the factory.
[4][7]Freeze the design input
Send controlled 3D data and drawings together with material, datums, critical characteristics, quantities and your own standards. Clear any drawing-model differences before tooling starts.
Review the process route
Ask which features are cast, which are machined and which come from an assembly partner, and who owns tooling and fixtures. Allied lists NX, VERICUT and MAGMA among its engineering tools; ask whether casting or machining simulation will be run for your part.
Approve the trial parts
Link prototype, inspection report and corrections to one drawing revision and process route. Allied describes trial self-inspection and corrective actions; request those records and decide whether a production trial follows.
Release serial production
Agree change control for tooling, material, sites and programmes, and the traceability and approval package for series parts.
Casting and machining: what to specify
Allied casts in sand moulds or printed moulds and cores, with induction melting, pouring, cooling, cleaning and inspection. Machining then sets the reference surfaces, brings the part to final size and checks geometry and surface finish. A reducer housing with coaxial bearing seats needs tighter control than a bracket, so specify the delivered state and the features that make the part fit.
[5][6]| Process stage | What to define for your part |
|---|---|
| Casting blank | Material grade, casting revision, machining allowance, allowed repairs and the features checked before machining. |
| Machining datums | The surfaces and bore axes that locate the part and their tolerances. Ask for the fixture and measuring plan for your part. |
| Surface and protection | Which faces are painted, plated, protected or left clean. Allied mentions paint, plating and anti-corrosion protection; agree the coating and storage life for your part. |
| Testing | Allied's process mentions strength, density and pressure tests. Name the tests your part needs, with method and pass criteria; set a test pressure for housings that hold oil or pressure. |
Traceability, X-ray and CMM checks
Allied codes each part through casting, machining and finishing, passes data automatically between steps, probes parts during machining, uses X-ray flaw detection and measures on a CMM. Each method answers a different question: probing catches clamping or size errors on the machine, the CMM checks drawn geometry, and X-ray looks for internal defects.
In the quality plan for your housing, tie each critical feature or defect type to its drawing requirement, measuring method, report format and sampling rate. Ask how a finished part is linked back to its casting heat, machining operation and inspection record, and how that link survives coating and shipping. Agree how parts outside tolerance are held, and how repairs or concessions are approved and logged. When comparing quotes, compare this coverage line by line. Ask Allied for capability data or defect rates on similar parts if you need them.
[6][7]Certificates and what they cover
Allied's profile lists ISO quality, environmental and occupational-health management systems, ASME/PED pressure-related qualifications and BV classification certificates. These cover the company and its processes. For a farm-machinery part, ask which site and process each certificate covers.
[2][3][8]| Item | What it means for your order |
|---|---|
| Before relying on a certificate | Ask for the certificate itself with holder, site and process covered, date and scope, and check it against the company on your contract. |
| Your finished machine | Conformity of the tractor, harvester or drone you build remains with the machine maker. Keep it separate from the supplier's management-system certificates. |

[3]Is the main reducer housing a complete gearbox?
The catalogue lists the housing. If you need gears, shafts or an assembled unit, state that and the ratings in your enquiry.
[3]Can I order a replacement part from the website picture?
Will every part get X-ray and CMM checks?
Allied lists both methods. Agree in the quality plan which features are checked, by which method and at what sampling rate.
[7]What does the September 2026 filing tell me?
It confirms the legal name, founding date and Hangzhou address in a dated stock-exchange notice.
