Data Center Liquid Cooling | Precision Cooling Components
CHX Metal (Shenzhen Changhexin Precision Hardware) produces data center liquid cooling components — cold plates, connectors and manifolds — with ±0.005mm tolerance and 100% leak testing. ISO 9001:2015 certified. The factory covers 5,000 m2 and produces up to 5 million precision parts per month.
Components
- Cold plates (vacuum-brazed)
- Quick-disconnect connectors
- Manifolds and distributors
- Blind-mate server connectors
Manufacturing
- CNC machining aluminum/stainless
- ±0.005mm on sealing faces
- 100% leak test (pressure decay)
- Anodizing and passivation
Why Precision Matters
Cooling loops demand zero leakage. Sealing surfaces are machined to ±0.005mm and every part is leak-tested.
Quality
ISO 9001:2015 certified with 100% leak testing and dimensional inspection.
Frequently Asked Questions

Materials & Specifications
We machine data center liquid cooling from 3003 aluminum, C1100 copper, SUS316. Typical accuracy is ±0.005mm, fully leak and pressure tested. Parts are manufactured to your 2D drawing or 3D model, in sizes from a few millimeters up to 1000mm envelopes, from single prototypes to hundreds of thousands of pieces per year.
Typical Applications
- server CPU/GPU cold plates
- CDU manifolds and pumps
- rack coolant distribution
- quick disconnect fittings
These are representative examples; we regularly take on custom geometries outside this list. Send your drawing for a feasibility check.
Our Machining Capability
Production runs on 3-axis and 5-axis vertical machining centers, CNC lathes, and Swiss-type automatic lathes. Fixtures are designed in-house for repeatable clamping, and programs are simulated before cutting to protect tight tolerances. Our ISO 9001:2015 quality system covers the full process chain: incoming material verification, tool wear monitoring, SPC on critical features, and final release inspection. Traceability is maintained lot by lot, so any part we ship can be traced back to its material batch, machine, and operator.
Surface Finishing Options
Available finishes include Type II and Type III anodizing (clear, black, and custom colors), sandblasting, wire drawing, laser engraving and silk-screen marking, zinc and nickel plating, passivation, and black oxide. Cosmetic parts are inspected under standardized lighting with defined surface criteria.
MOQ, Lead Time & Packaging
We hold safety stock for repeat customers and support Kanban or VMI delivery schedules for long-running programs. Every shipment includes packing list, material certificates, and inspection report. Direct express shipping worldwide from Shenzhen typically reaches Europe and North America in 3-6 days.
Why Choose CHX Metal
Located in Bao'an, Shenzhen, we ship from one of the a highly connected manufacturing hub, 30 minutes from the airport and one hour from Yantian port. That means more courier options, faster transit, and lower logistics cost for your supply chain.
