6

Inspection & Testing

Every liquid-cooling kit is leak-tested and performance-checked against the agreed acceptance criteria before packing.

Inspection Process for Liquid-Cooling Kits

Thirteen checkpoints between machining and shipment — not a final spot check.

Helium Leak Test Air Leak Test Pressure Holding Test Flow Resistance Test Pulse Flow Test High-Temperature Channel Flushing Vacuum Baking Thermal Resistance Test Ultrasonic Scanning (SAT) X-Ray Scanning Cleanliness Test Salt Spray Test Cleanroom Packing

Factory & Equipment

Take a walk through our 60,000 m² manufacturing centre in Qingxi, Dongguan — CNC machining, skiving, FSW, brazing, die casting and heat-pipe lines under one roof, backed by a dedicated quality centre for helium leak, flow, thermal, X-ray and ultrasonic testing. A second plant is under construction in Chonburi, Thailand for overseas programmes.

How We Work

No black box. You always know which step your project is in and who is working on it.

01

Send Drawings & Requirements

Share 2D/3D files, thermal load, flow rate, pressure budget and the available envelope. A rough sketch is enough to start.

02

Thermal Design & DFM Proposal

Our engineers propose the cooling structure, material, process route and tooling, and flag manufacturing risks — usually within 24–48 hours.

03

Prototype & Validation Testing

First articles in 7–15 days, then measured in our own lab: thermal resistance, pressure drop, flow rate and leak tightness.

04

Mass Production & Delivery

APQP-controlled mass production with PPAP documentation, 100% leak testing, cleanroom packing and shipping from Dongguan or Thailand.

Frequently Asked Questions

−What is the minimum order quantity for custom cold plates?

Samples and prototypes start from a single piece — we run a dedicated sample team so first articles do not queue behind production. Mass production typically begins at 100–500 pieces depending on the process (skiving, FSW, vacuum brazing), and we will tell you the economic break-even point before you commit.

+How fast can I receive a quotation and samples?

Send your 2D/3D drawing or even a concept sketch with the thermal load, flow rate and available envelope. Quotations are normally returned within 24 hours and the design proposal within 24–48 hours. After drawing confirmation, samples are typically delivered in 7–15 days.

+Which processes do you use for liquid cold plates?

Embedded copper tube, friction stir welding (FSW), vacuum brazing, copper and aluminium brazing, laser welding, high-frequency welding, diffusion bonding, die casting, stamping, skiving and micro-fin machining. Choosing between them is a cost-versus-performance decision we will make with you.

+How do you guarantee leak tightness and cleanliness?

Every liquid-cooling kit passes a 100% helium leak test, with air leak and pressure-holding tests where the specification requires them. We also run flow-resistance, pulse-flow and thermal-resistance tests, ultrasonic scanning, X-ray inspection and cleanliness checks, then assemble and pack in a 100K-class cleanroom.

+Can you support automotive-grade and AI server programmes?

Yes. We are IATF 16949 certified and work to an APQP development flow with PPAP documentation. Battery cold plates are in mass production for major Chinese EV makers; ADAS cooling modules are running in more than 250,000 vehicles; and our cold plate assemblies serve flagship GPU super chips and AI server water-cooling platforms.

+Where are you located, and do you export worldwide?

Our head factory is in Qingxi, Dongguan, Guangdong, China, with 60,000 m² of manufacturing area, and a second plant is under construction in Chonburi, Thailand to support overseas programmes. We ship to North America, Europe, Japan, Korea and Southeast Asia, and we are happy to work through your forwarder or ours.
