Custom Integrated Liquid Cooling Flange
The integrated design of our liquid cooling flanges helps optimize fluid flow paths, improve heat transfer efficiency, and maintain stable performance under demanding operating conditions. These components are widely used in automotive cooling systems, industrial equipment, power generation systems, marine applications, and other thermal management solutions.
OEM Manufacturing Process
We provide complete manufacturing solutions from design evaluation to final delivery:
- DFM Analysis & Engineering Review
Our engineering team evaluates customer designs to optimize casting feasibility, wall thickness, machining allowance, and production efficiency while maintaining required performance standards.
- Investment Casting Production
Using advanced lost wax casting technology, we manufacture complex metal structures with excellent surface quality and near-net-shape accuracy. This process reduces machining waste and enables the production of lightweight yet strong components.
- CNC Machining & Finishing
Critical mounting surfaces, connection ports, holes, and sealing areas are precision machined to achieve accurate dimensions and reliable assembly performance.
- Inspection & Quality Control
Each component undergoes dimensional inspection, material verification, and appearance checks to ensure compliance with customer specifications before shipment.
Materials and Technical Capability
We manufacture cooling flanges using a wide range of engineering metals, including:
- Stainless steel: 304, 316, 316L, CF8M, duplex stainless steel
- Carbon steel: WCB, 20#, 45#
- Alloy steel: 42CrMo and other customized grades
- Aluminum alloys: A356 and other casting alloys
Typical manufacturing capabilities include:
- Single piece weight: 0.05–15kg
- Maximum casting size: 600×600×400mm
- Critical casting tolerance: ±0.2mm
- As-cast surface finish: Ra3.2–6.3μm
- CNC machining tolerance according to customer requirements
Investment casting allows us to create complex integrated structures that are difficult to achieve through traditional manufacturing methods. By reducing welded joints and assembly connections, the flange design improves sealing reliability and minimizes potential leakage risks in liquid cooling systems.

Quality Assurance
Quality control is integrated throughout our production process. We utilize advanced inspection equipment including CMM coordinate measuring machines, X-ray testing, and material composition analysis to verify product quality.
Our manufacturing system follows ISO9001 and IATF16949 quality management standards. Material traceability documents, inspection reports, and production records can be provided according to customer requirements.
For carbon steel components, we also offer surface treatments such as passivation and vibratory finishing to improve corrosion resistance, surface appearance, and long-term durability.
Applications
Our precision liquid cooling flanges are suitable for various industries, including:
- Automotive and commercial vehicle cooling systems
- Industrial machinery thermal management
- Marine engine cooling systems
- Renewable energy equipment
- Data center cooling solutions
The Custom Integrated Liquid Cooling Flange provides an effective solution for customers requiring strong mechanical performance, accurate installation dimensions, and reliable fluid sealing capability.
