Material Selection by Coolant Type

We match material and surface treatment to your coolant chemistry, not a generic default.

Material	Compatible Coolants	Key Property	Typical Application
304/316 Stainless	Water, glycol, PAO	Corrosion resistance	Data center CDU manifolds
6061-T6 Aluminum	Dielectric fluids	Lightweight, anodized seal	EV battery cooling plates
Brass C36000	Deionized water	Machinability, cost	Industrial process chillers
Custom alloys	Per specification	As required	Aerospace cold plates

Every heat ships with mill test reports (MTR) and optical emission spectrometry verification.

CNC Machining Capability

Our Ningbo facility machines Liquid Cooled CNC Machined Quick Coupler components with parameters tuned for seal integrity and flow performance:

Parameter	Specification
Max body diameter	80 mm
Max overall length	150 mm
Thread accuracy	ISO 6H / 6g or tighter per drawing
O-ring groove concentricity	≤ 0.02 mm
Sealing surface roughness	Ra 0.8–1.6 μm
Internal passage surface finish	Ra 3.2 μm (minimizes pressure drop)
Equipment	4-axis turning center + 5-axis VMC

DFM Analysis for Quick Couplers

We optimize for liquid cooling reliability before cutting metal:

Wall thickness uniformity: Prevents distortion during brazing or welding of adjacent manifold plates
Flow path radius: Internal edges radiused to ≥ 1 mm to eliminate turbulence and cavitation
Seal groove location: Positioned away from thread runout to prevent O-ring extrusion under pressure
Retaining feature design: Snap-ring or bayonet grooves machined to ±0.05 mm for consistent retention force

Quality Inspection Protocol

Inspection targets the failure modes that actually stop cooling systems:

Check	Method	Standard / Tolerance
Body diameter & length	CMM	±0.05 mm
Thread pitch diameter	Thread gauge + CMM	ISO 1502
O-ring groove width/depth	Optical comparator	±0.02 mm
Internal passage cleanliness	Particle counter	ISO 4406 Class 18/16/13
Seal integrity	Pressure decay test	≤ 0.1 mL/min leak at 1.5× working pressure
Material verification	OES spectrometry	Per batch

Certifications: IATF 16949 · ISO 9001 · Full lot traceability from raw material heat number to finished part
