The Hydroformed Aluminum Gyro Housing is produced by Aunov Tech from aluminum, formed and finished under one roof. In duty, the drawn housing encloses the sensitive internals and carries the mounting interface. One production floor covers forming, finishing and inspection, and a design change is re-sampled in one place without handing the part to another vendor.
Product overview
For this aluminium housing, the drawing centres on, wall thinning, concentricity and the finished mating faces, each measured at first article and gauged on production batches.
Die work and machining for this aluminium housing sit on the same floor, so feasibility questions are answered on the shop floor, with the tooling history retained in house.
Production route
Every aluminium housing follows the same routed path: A tube preform is expanded against the die by internal pressure; wall thickness is checked around the expanded contour after forming.
Every dome cover order keeps its trace back to the approved first article, and a reorder is a repeat rather than a new start. Mill certificates are filed per heat, so dome cover traceability survives a change of material batch.
Materials and finishing
Base materials in stock: carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and the grade agreed for this aluminium housing is aluminium.
The finish is chosen for the duty it will see: zinc and nickel plating, chrome, anodising, powder coating and passivation. The agreed finish for this aluminium housing travels with the part number on every reorder.
Every dome cover order keeps its trace back to the approved first article, and a reorder is a repeat rather than a new start. The signed dome cover sample remains the reference and is kept with the job file.
Quality control and inspection
An ISO 9001 certified system governs production: certificates verify each incoming batch of material, the first article is CMM-measured against the print, and production batches are inspected on a sampling plan. For the dome cover, cavity depth and seal face finish are checked at first article. Where the application asks for it, torque, leak or pressure testing is added to the plan, and the batch file carries the results.
Applications
Typical installation of the aluminium housing is in industrial equipment and general assembly work across automotive, appliance and industrial programmes.
The same aluminium housing is often run in more than one assembly, so wall bands and finishes are selected to cover the widest duty, and approvals carry across programmes.
Customization and options
What customers usually vary
Typical decisions customers make on this aluminium housing: grade and finish for the environment, wall thickness bands, flange and rim forms, threads, bosses and closed ends, and the batch pattern – prototype, pilot lot or scheduled production.
Tooled and untooled options for this aluminium housing are listed separately, so new tooling is only quoted where it is genuinely required. Repeat orders of the dome cover keep the same cost split.
Specifications
| Item | Hydroformed Aluminum Gyro Housing |
|---|---|
| Brand | AUNOV |
| Designing | Quotation follows the print, not a catalogue – DFM notes are returned before any tooling is cut; changes are priced before they are made. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so tooling lead time stays under our control, and the charge is refundable against agreed volumes. |
| Samples | First-article samples ship with a dimensional report and material certificate, so the approved first article becomes the gauge reference, and production starts only after your written sign-off. |
| Materials | 1050 / 3003 / 5052 / 6061 aluminium, 0.5-3.0 mm stock – temper matched to the forming depth or machining route of this housing. |
| Surface finish | Finish selected from the drawing: plating, coating, anodising or passivation; alternatives quoted with the quotation, samples approved in writing. |
| Processing | Tube or sheet preform, hydroforming into the finished contour, trimming, then annealing and finishing. |
| Equipment | Mechanical presses 5-250 T plus 250-500 T hydraulics, with in-line annealing, with in-house toolmaking to keep dies and fixtures maintained. |
| Tolerance | +/-0.03 mm on turned secondary features, +/-0.1 mm on as-drawn walls; finer bands confirmed from capability data before quoting. |
| Delivery terms | FOB Ningbo or Shanghai, payment by T/T or L/C, quoted in USD or EUR; price breaks tie to annual volume. |
Packing and shipment
Finish comes first when packing this aluminium housing: interleaving, bagging or tray packing is matched to the surface, then cartons are sealed and palletised, with marks and documents as you specify.
