Direct answer: Zhengna Technology manufactures custom brass machined parts for connectors, fittings, terminals, bushings, threaded shafts, and electronic hardware. OEM buyers can use this page to confirm drawing inputs, machining risks, finish requirements, and inspection expectations before sending an RFQ.
| RFQ detail | Why it matters |
|---|---|
| Drawing and 3D model | Defines dimensions, tolerances, features, mating surfaces, and manufacturability risks. |
| Material and finish | Controls strength, corrosion resistance, conductivity, appearance, and machining stability. |
| Critical features | Identifies threads, bores, grooves, flatness, concentricity, sealing surfaces, or contact areas. |
| Inspection plan | Confirms critical dimensions, gauges, sample approval, and shipment documentation. |
For brass machined parts, Zhengna Technology reviews brass material review, CNC turning, drilling, threading, deburring, surface finishing, and inspection before confirming the production route. This helps reduce tolerance drift, burr issues, finish defects, thread problems, and assembly risk.
Send drawings, 3D files if available, material grade, critical dimensions, tolerance requirements, surface finish, application environment, and expected volume.
Yes. Zhengna Technology manufactures made-to-drawing parts and reviews machining route, material, tolerances, finish, and inspection requirements before quotation.
Quality control focuses on material checks, critical dimensions, burr and surface finish, thread or fit requirements, in-process inspection, and shipment records.
