Automotive housings and structural parts
Structural loads, machined datums, porosity acceptance and production approval.
Housings, brackets, lighting components and thermal parts made to drawing through our long-term strategic manufacturing bases. Review the tooling, production route, quality plan and total cost with one Ningbo Empire team.
The actual producing site, machine, tooling responsibilities and inspection scope are confirmed against your component.
Send drawings, alloy requirements, critical features and demand. Review draft, wall sections, machining stock and the proposed process.
Agree the tooling scope, first-article measurements, material checks and any leak or porosity acceptance criteria.
Confirm releases, quality controls, packing, material purchasing and tooling maintenance responsibilities.
Set shipment documents, delivery terms and customer-approval rules for material, tooling, process or site changes.
The consolidated equipment inventory covers 46 aluminum-alloy machines and 4 zinc-alloy machines across Ningbo and Jiangsu. Project routing is confirmed against part size, projected area, alloy and annual volume.

Representative component forms. Your material, geometry, finish and inspection requirements define the quoted part.




Die casting can combine complex geometry with repeatable production once the volume supports the tooling investment. Compare it with other casting routes or machining against the actual part and demand.
| Component | Key review points |
|---|---|
| Electronics enclosures | Sealing faces, connector interfaces, grounding and finish. |
| Motor & gearbox housings | Bearing bores, concentricity, mounting datums and thermal requirements. |
| LED lighting housings | Thermal path, fin geometry, mounting, appearance and weather exposure. |
| Automotive brackets | Load cases, critical features, traceability and customer qualification. |
| Power-tool housings | Assembly interfaces, impact requirements, finish and production quantity. |
Machine tonnage is not a part-size guarantee. Projected area, cavity count, alloy, part envelope and process requirements determine the proposed machine and tooling.
| Item | Scope | Confirm during quotation |
|---|---|---|
| Aluminum clamping-force range | 130–4,400 tons across the reported network | Machine assignment, shot requirements, availability and production location. |
| Equipment total | 46 aluminum machines; 4 zinc machines across five reported groups | The equipment summary is a network inventory, not reserved capacity for a new order. |
| Manufacturing locations | Ningbo, Zhejiang and Jiangsu | Producing site and relevant quality documents. |
| Aluminum alloys | A380, ADC12, A360 and A413 are reviewed against the application | Required standard, composition, properties and material records. |
| Secondary operations | CNC machining, drilling, tapping and finishing | Datums, tolerances, surface requirements and the approved operation sequence. |
| Wall sections & dimensions | Evaluated per feature and casting geometry | Fill behavior, draft, porosity risk and any machining allowance. |
| Surface finish | As-cast, machined and coating routes | Appearance sample, surface roughness, coating thickness and corrosion requirements. |
| Separate zinc route | 88–160-ton equipment for zinc die-casting projects | Review zinc components → |
A380 and ADC12 are distinct designations. Do not replace one with the other without reviewing the applicable composition limits, required properties and customer approval.
| Material | Selection discussion |
|---|---|
| A380 | Common aluminum-silicon-copper die-casting alloy; review the exact drawing standard. |
| ADC12 | A separate aluminum die-casting designation; verify the specified JIS requirements rather than treating it as A380. |
| A360 / A413 | Evaluate against the part's corrosion, casting and pressure-integrity requirements. |

No automatic substitution should be assumed. A380 and ADC12 are distinct aluminum die-casting designations with different composition limits. Specify the required standard and edition, then confirm composition, properties and customer approval for any proposed alternative.
Part size, cavity count, slides, tool material, expected production volume and maintenance requirements all influence the quotation. Tool ownership, payment milestones, maintenance, storage and transfer conditions should be agreed in writing before the tooling order.
The practical order quantity depends on the part, tooling, alloy and production route. Share sample quantity, annual demand and release sizes so we can compare the proposed die-casting route with alternatives such as CNC-machined prototypes. MOQ and lead time are confirmed in the quotation.
Some die-cast alloys can be anodized, but alloy composition and casting quality affect the result. High-silicon casting alloys can show cosmetic variation. Agree a finish sample and the required appearance, corrosion performance and dimensional allowance before selecting anodizing or a coating alternative.
Send the drawing, annual volume, finish and acceptance requirements. We will review the proposed manufacturing route and quotation inputs.
