Custom Liquid Cooling Plates From China
Sino Supply Works helps overseas buyers prepare practical RFQs for liquid cooling plates and custom cold plates. Drawings, material, coolant, pressure, channel design, flatness, leak testing and packaging are clarified before suitable Chinese supplier resources are asked to quote.
Send drawings, specifications, item lists or project details. Sino Supply Works will review the RFQ and reply with the next practical step.
Start RFQOverview
What this sourcing page helps you clarify.
This page is for engineers and sourcing managers who need a custom liquid cooling plate supplier in China, but also need clear coordination before quotation. Sino Supply Works helps organize technical details so manufacturers can review the same scope.
Capabilities
China sourcing scope before supplier quotation.
These are the typical manufacturing and sourcing questions Sino Supply Works helps organize before Chinese suppliers review the RFQ.
Manufacturing route review
CNC machined channels, brazing, vacuum brazing, friction stir welding and tube embedded routes reviewed case by case.
Ports and manifolds
Connection type, manifold layout, sealing surfaces and assembly details are clarified before quotation.
Sample and batch follow-up
Prototype, sample inspection, pressure test and production follow-up questions stay visible.
Materials
Materials and process inputs
- Aluminum for EV battery packs, energy storage and data center cooling
- Copper when thermal conductivity is the main driver
- Stainless steel only when corrosion, hygiene or system integration requires it
- Surface finish, coating, cleaning and packaging agreed by RFQ
Applications
Typical industrial applications
- EV battery and energy storage systems
- Data center liquid cooling
- Power electronics and charging systems
- Industrial lasers and refrigeration equipment
Custom options
Details to define before a serious quotation.
- Channel pattern and flow path
- Plate size, flatness and critical tolerances
- Port thread, brazed fitting or welded fitting
- Leak rate, pressure test and cleaning method
- Sample quantity, annual volume and destination
Quality control
Inspection and follow-up points for overseas buyers.
Quality control is confirmed according to drawing, supplier capability and order scope. The goal is to make assumptions visible before production or shipment.
Dimensional Inspection Against Drawings
Key dimensions, hole positions, tolerances, and critical features are checked against buyer drawings before production follow-up.
Flatness and Sealing Surface Checks
Flatness, sealing grooves, gasket contact areas, and surface finish requirements are clarified when they affect assembly or leak prevention.
Leak Testing and Pressure Testing
Test pressure, holding time, medium, acceptance criteria, and report requirements are confirmed before supplier quotation or shipment.
Cleaning, Drying and Protective Packaging
Internal channels, machined surfaces, threads, ports, and sealing areas are protected according to the product type and shipping method.
Inspection Photos or Reports When Requested
Photos, videos, dimensional records, pressure test records, or supplier inspection reports can be coordinated before final shipment.
