Direct answer: Zhengna Technology manufactures custom CNC machined aluminum parts for automation equipment, electronics hardware, automotive components, brackets, housings, and precision assemblies. This page helps OEM buyers check drawing requirements, process risks, and quality-control points before sending an RFQ.
| Item to confirm | Why it matters for production |
|---|---|
| Drawing and 3D model | Confirms dimensions, tolerances, assembly interfaces, and manufacturability risks. |
| Material and finish | Controls strength, corrosion resistance, conductivity, appearance, and working environment fit. |
| Critical function | Identifies load, torque, fit, movement, sealing, electrical, or cosmetic requirements. |
| Inspection plan | Defines critical dimensions, sample approval, in-process checks, and shipment documentation. |
For cnc machined aluminum parts, Zhengna Technology reviews aluminum material review, CNC milling, CNC turning, drilling, tapping, anodizing or finish review, and inspection before confirming the stable production route. The goal is to reduce tolerance drift, surface defects, assembly problems, and late engineering changes.
Send drawings, 3D files if available, material grade, surface finish, key dimensions, application environment, quantity forecast, and inspection requirements.
Yes. Zhengna Technology focuses on made-to-drawing OEM parts and can review process route, tooling, material, finish, tolerance, and inspection needs before quotation.
The team separates critical-to-function dimensions, checks material and process risks, verifies surface or fit requirements, and uses inspection records aligned with the buyer drawing.
