Direct answer: Zhengna Technology manufactures made-to-drawing precision metal components for AI data center liquid cooling and power hardware, including liquid cooling connectors, manifold parts, cold-plate-related metal parts, copper busbars, stamped brackets, sensor mounts, spring clips, fasteners and small assemblies.
AI server and high-density rack projects create new requirements for thermal and electrical hardware. The strongest buyer value is not a generic catalog part, but a supplier that can review drawings, material, surface treatment, sealing surfaces, burr control, cleanliness, inspection and packaging together before quotation.
| Component | Manufacturing route | Inspection focus |
|---|---|---|
| Liquid cooling connectors | CNC machining, Swiss machining, turning, threading | O-ring groove, thread gauge, surface finish, burr control |
| Manifold and cold-plate-related parts | CNC milling, drilling, tapping, surface treatment | Flatness, port alignment, sealing surface, cleanliness |
| Copper busbars and conductive parts | Stamping, CNC machining, bending, plating | Conductivity, hole position, edge radius, plating thickness |
| Brackets, clips and mounts | Stamping, sheet metal fabrication, spring forming | Bend angle, burr direction, vibration resistance, cable clearance |
| Fasteners and assembly kits | Cold heading, machining, assembly, packaging | Thread fit, coating, torque behavior, lot traceability |
Zhengna Technology focuses on custom precision metal component manufacturing from buyer drawings. System architecture and thermal simulation are usually handled by the OEM or cooling-system integrator.
Yes. Prototype CNC parts can be reviewed for production by optimizing geometry, inspection points, surface treatment, packaging and possible tooling or stamping routes.
Drawings, 3D files, material, surface treatment, sealing requirements, leak-test expectations, cleanliness notes, quantity and inspection requirements help quotation accuracy.
Short answer: A cold plate RFQ should connect the heat-source map, coolant and pressure conditions, thermal-interface datum, channels, ports, sealing or joining responsibility, cleanliness, leak-test criteria, inspection records, and production volume.

Liquid-cooling hardware is only one part of an AI server assembly. Dense rack systems may also require precision springs, slide rails, brackets and connector components that are validated for load, tolerance, service access, sealing interface and inspection consistency.
