Introduction: When an Industry’s Demand Shifts from “Steady Growth” to “Forced Switching”
In 2024, China’s sheet metal processing industry reached approximately ¥37.7 billion in market size, with the global market at around $17.5 billion, growing at 3–6% annually—typical numbers for a mature industry, neither hot nor cold.
But in 2025, a crack is tearing through this calm surface:
Global liquid-cooled data center market: $4.87 billion, up 41.2% YoY
China’s liquid-cooled server market: surging 67% YoY
AI server cabinet demand: jumping from 28,000 units to at least 60,000 units
This is not incremental demand from a new customer base—it is the underlying technology roadmap of the entire cabinet industry being forced to switch. Air cooling to liquid cooling is not optional; it is mandatory.
When the structure of demand undergoes a fundamental shift, what is happening in the sheet metal processing industry? Is it a brief pulse of orders, or a historic inflection point in supply and demand?
Chapter 1: Liquid-Cooled Cabinets—A New Species in Sheet Metal Fabrication
1.1 Why Liquid-Cooled Cabinets Fundamentally Change Sheet Metal Requirements
Liquid cooling is not simply adding a water pipe to a standard cabinet. It is a precision fluid system nested within a sheet metal structure.
In one sentence: Liquid-cooled cabinets elevate sheet metal fabrication from “structural component manufacturing” to “precision fluid system integration.”
1.2 Three Liquid Cooling Technology Routes and Their Different Sheet Metal Requirements
Technology Route | Core Sheet Metal Requirements | Key Challenges |
Cold Plate (Contact) | Cold plate runner seal welding; mounting surface flatness ≤ 0.05 mm; cabinet structural strength | Sealed weld quality directly determines cooling efficiency; any leak = system failure |
Immersion Cooling | Fully sealed tank fabrication; internal corrosion-resistant coating; fluid-tight full-penetration welds | Cabinet must hold dielectric fluid; highest sealing and corrosion requirements |
Rear-Door / Heat Exchanger | Heat exchanger frame precision; pipe routing full-penetration welding; ≥300 kPa pressure-bearing | Pipe weld quality under pressure; structural frame accuracy affects thermal contact |
1.3 Core Sheet Metal Process Chain for Liquid-Cooled Cabinets
Laser Cutting
CNC Bending
Precision Welding
Cold plate runner seal welding
Pipe fitting full-penetration welding
Leak-proof tray continuous full weld
Structural frame strength welding + cosmetic welding
Electrostatic Powder Coating
Exterior shell: standard powder coating
Internal cavity: three-proof anti-corrosion coating
Sealing surfaces: flatness ≤ 0.05 mm
Assembly + Leak Testing
Key Insight: No link in this process chain can be outsourced. Precision, sealing integrity, and anti-corrosion requirements are tightly interlocked. Outsourcing any single process step may cause the final leak test to fail.
Chapter 2: Market Drivers—Why This Is the Most Certain Demand Growth in Sheet Metal for the Next 5 Years
2.1 AI Compute: From “Optional” to “Mandatory” Forced Switching
Underlying logic: AI chip power consumption doubles every 18 months, and the physical limit of air cooling is around 30 kW per cabinet. When single-cabinet power exceeds this threshold, liquid cooling is not “a nice-to-have”—it is “without liquid cooling, the system cannot operate.”
This means: every new AI server cabinet represents a new sheet metal order for a liquid-cooled cabinet.
2.2 CNC Cabinets: Structural Expansion Driven by Industrial Intelligence
Growth drivers: New energy vehicles, smart grids, Industry 4.0, and semiconductor capacity expansion—every track is pulling demand for high-end precision cabinets.
2.3 Energy Storage Cabinets: Another Explosion Point on the Liquid Cooling Path
In 2025, China’s new energy battery housing market reached $22 billion, with liquid-cooled integrated energy storage cabinets rapidly replacing air-cooled solutions. Orders for 350 MWh-class liquid-cooled energy storage cabinets have been delivered in bulk, and each storage cabinet requires precision sheet metal enclosure + liquid cooling system + anti-corrosion treatment.
Liquid-cooled cabinets + CNC cabinets + energy storage cabinets—three demand streams superimposing—are creating the largest structural demand inflection point in the sheet metal processing industry in nearly a decade.
Chapter 3: Analyzing the Sheet Metal Industry Through a Supply-Demand Framework—A “Tipping Point” Already Underway
3.1 The Sheet Metal Inventory Cycle: A Mirror Comparison with Baijiu
Dimension | Baijiu (Liquor) Industry | Sheet Metal Industry (2025) |
Supply–Demand State | Massive overcapacity, destocking phase | Shortage of high-end capacity, demand surging |
Industry Concentration | Highly fragmented, thousands of distilleries | 95% of shops do only 1–2 processes |
Technology Route Change | No, traditional brewing stable | Yes, air cooling → liquid cooling forced switch |
Entry Barriers | Low (technical) + High (brand/channel) | Low (basic) + High (full-chain + env permits) |
Inventory Cycle Stage | Late-cycle destocking, 5–8 years | Early-cycle capacity shortage, just beginning |
3.2 Mapping Fu Haitang’s “Gap Theory” onto the Sheet Metal Industry
Fu Haitang’s core formula:
Production − Inventory − Demand = Gap
In the sheet metal industry, this formula becomes:
Capacity meeting liquid-cooled precision − Legacy non-liquid-cooled capacity − AI/storage incremental demand = ?
Current data estimates:
High-end sheet metal capacity (full-chain, high-precision, in-house coating): less than 5% of China’s total
Liquid-cooled cabinet incremental demand: 40%+ CAGR from 2025–2027
Gap assessment: high-end precision sheet metal capacity is severely insufficient; the gap has emerged and continues to widen
3.3 Why Is This Inflection Point “Certain”?
Fu Haitang’s core criterion for certainty—extreme signals appearing simultaneously across multiple dimensions:
Dimension | Signal |
Demand Scale | Liquid-cooled data center market surging 41.2% YoY; energy storage cabinets entering volume production |
Technology Forcing | AI chip power exceeds air cooling limit; liquid cooling is the only viable path forward |
Supply Constraints | < 5% of shops have full-chain capability; environmental permit barriers limit expansion |
Capacity Build-up Time | Building a full-chain precision sheet metal line takes 2–3 years; cannot respond to sudden demand spikes |
Structural Irreversibility | Once data centers adopt liquid cooling, they will not revert to air cooling |
All 5 dimensions point to the same conclusion: high-end precision sheet metal capacity is at a structural inflection point where supply falls short of demand.
Chapter 4: DINGPRECISION—Why Full-Chain Capability Is Perfectly Positioned at This Inflection Point
4.1 Liquid-Cooled Cabinet Demand × Full-Chain Capability = Perfect Match
Liquid-Cooled Cabinet Requirement | DINGPRECISION Capability | Advantage |
Laser cutting ±0.1 mm | In-house fiber laser cutting | No outsourcing, zero communication loss |
CNC bending ±0.2 mm | Multi-axis CNC press brakes | Frame parallelism guaranteed |
5 welding processes | TIG/MIG/MAG/laser/spot | Full process coverage for all joint types |
Powder coating + anti-corrosion | In-house coating line + env permits | Complete control of surface quality |
250 kPa leak testing | In-house pressure test station | Delivery only after passing leak test |
4.2 Why “One-Stop Full-Chain” Is Irreplaceable in This Space
Liquid-cooled cabinet sheet metal fabrication has a characteristic that standard cabinets do not—strong process coupling:
Bending precision directly affects welding seal integrity
Welding distortion directly affects coating adhesion
Pre-coating surface treatment directly affects sealing surface flatness
Distributing 4 process steps across 4 different factories causes tolerances to accumulate at each stage, ultimately exposed during the final leak test.
This is DINGPRECISION’s greatest advantage with its “one-stop full-chain” model—tolerances are absorbed internally; only qualified products are delivered externally.

Conclusion: When a Demand Inflection Meets a Capability Barrier
The inventory cycle in the baijiu (liquor) industry teaches us a lesson: when supply far exceeds effective demand, prices keep falling until capacity is cleared. But the industry’s characteristics mean the clearing cycle lasts 5–8 years.
What is happening in the sheet metal industry is the exact opposite story:
Demand is surging (AI compute + energy storage + industrial upgrade), but effective supply (full-chain, high-precision sheet metal capacity) is severely insufficient. This is not the painful destocking of “inventory clearance”—it is the structural opportunity of “supply falling short of demand.”
95% of sheet metal shops handle only 1–2 processes and cannot meet the precision and sealing requirements of liquid-cooled cabinets. The barrier of environmental coating permits further compresses effective supply.
When surging demand + constrained supply + rising barriers appear simultaneously—
This is exactly what Fu Haitang calls “certainty”—multiple dimensions simultaneously pointing to a supply-demand inflection point, an irreversible trend.
DINGPRECISION is already fully positioned.
