Complete Liquid Cooling Cabinet Production Line

Step 01 / 09Liquid Cooling Cabinet

Raw Sheet Metal

Liquid cooling cabinet production starts with cold-rolled steel, stainless steel, or aluminum sheet. Material is graded by thickness and batch, then prepared for chassis and manifold panel machining.

• Carbon steel, stainless steel & aluminum supported
• Typical thickness: 1.0mm – 3.0mm for liquid-cooled chassis
• Flatness and surface inspection before cutting

Next: Fiber Laser Cutting

Step 02 / 09Liquid Cooling Cabinet

Fiber Laser Cutting

Fiber laser cutting produces cabinet chassis blanks, rear-door heat exchanger panels, hose port cutouts, manifold plates, and mounting slots with ±0.1mm accuracy for leak-critical assemblies.

• Coolant port, hose gland, and manifold cutouts
• RDHx door panels and side plenum blanking
• Stainless, aluminum, and mild steel processing

Next: CNC Turret Punching

Step 03 / 09Liquid Cooling Cabinet

CNC Turret Punching

CNC turret punching handles repeated mounting holes, vent patterns, and connector cutouts on identical liquid cooling cabinet panels — ideal for high-volume AI rack programs.

• Cage nut rails and GPU tray mounting patterns
• Vent grids and cable entry on manifold covers
• Batch production for standardized liquid-cooled models

Next: Bending

Step 04 / 09Liquid Cooling Cabinet

Bending

Press brakes and automatic panel benders form deep chassis sections, rear-door exchanger housings, CDU covers, and structural stiffeners with tight angle control for gasket-ready seams.

• ±0.1° bending accuracy on long chassis panels
• Panel bender for one-pass door and cover forming
• Deep-box forming for coolant distribution enclosures

Next: Welding

Step 05 / 09Liquid Cooling Cabinet

Welding

MIG, TIG, and laser welding join frames, manifold brackets, and fluid-path housings — delivering the structural strength and seam quality required for high-density liquid-cooled deployments.

• Frame corner and manifold bracket welding
• Low-distortion laser weld for visible fluid paths
• Post-weld dimension check before leak-test prep

Next: Grinding & Deburring

Step 06 / 09Liquid Cooling Cabinet

Grinding & Deburring

All laser-cut edges and weld seams are deburred and ground smooth — essential for O-ring sealing surfaces, safe hose routing, and uniform powder coating on liquid cooling enclosures.

• Burr-free edges on manifold and port panels
• Flush weld grinding on fluid-path interfaces
• Surface prep before phosphating or coating

Next: Powder Coating

Step 07 / 09Liquid Cooling Cabinet

Powder Coating

Electrostatic powder coating with curing oven delivers corrosion protection for facility CDU skids and server-side cabinets — typically RAL7035 with 500+ hour salt-spray rated finishes.

• RAL7035 / custom colors for data center environments
• Pre-treatment: degreasing and phosphating
• Even film build on deep chassis sections

Next: Assembly

Step 08 / 09Liquid Cooling Cabinet

Assembly

Chassis components receive rails, blanking panels, hose brackets, and coolant interface hardware. Door alignment, mounting rail spacing, and port positions are verified before integration.

• 19" / 21" rack rails and GPU tray brackets fitted
• Hose routing brackets and blanking panel install
• Dimensional QC against customer coolant layout drawings

Next: Finished Liquid Cooling Cabinet

Step 09 / 09Liquid Cooling Cabinet

Finished Liquid Cooling Cabinet

Completed liquid cooling cabinets, CDU enclosures, and rear-door heat exchanger assemblies pass final inspection and are packed for AI infrastructure builders and data center OEMs worldwide.

• Door gap, rail spacing, and port position verification
• Serial traceability for coolant-path sub-assemblies
• Export crate packing for overseas delivery
