Direct answer: Zhengna Technology manufactures custom faucet filter screens and inlet strainer parts for faucets, sanitary hardware, water inlet assemblies, plumbing strainers, and appliance water paths. The page is intended for OEM buyers who need drawing-based production, process review, and inspection support before placing an RFQ.
| RFQ item | What Zhengna Technology reviews |
|---|---|
| Drawing and 3D file | Critical dimensions, tolerance stack, assembly fit, and manufacturability risks. |
| Material and finish | Material grade, coating or plating needs, corrosion risk, appearance surface, and working environment. |
| Application load or fit | Mounting points, mating parts, vibration, wear, sealing, or electrical requirements where relevant. |
| Quality documents | Inspection dimensions, sample approval needs, material certificates, and shipment check records. |
For faucet filter screens, Zhengna Technology usually reviews mesh and metal material review, stamping, forming, assembly fit checks, corrosion-resistant finishing, and inspection before confirming the most stable production route. This helps reduce late design changes, finish defects, tolerance drift, and assembly problems.
Buyers should send drawings, 3D files if available, material grade, surface finish, key tolerance points, annual volume, application environment, and inspection requirements.
Yes. Zhengna Technology focuses on made-to-drawing components and can review tooling, process route, finish, tolerance, and inspection needs before quotation.
The team checks material, tooling or fixture condition, critical dimensions, surface finish, fit points, and shipment inspection records based on the drawing and buyer application.
