Precision-Etched Titanium Flow Plates for Heat Exchangers with High-Corrosion Resistance

Precision-Etched Titanium Flow Plates for Heat Exchangers with High-Corrosion Resistance

Flow Plate Overview
Xinhaisen Technology specializes in manufacturing high-precision chemically etched flow plates for plastic injection molding, die casting, and other industrial applications. Our flow plates offer superior flow control, exceptional durability, and precise channel geometries that optimize material distribution in production processes.

Flow Plate Features

• Complex, Burr-Free Channels: Etching produces smooth, precise micro-channels with no mechanical stress or burrs, ensuring optimal fluid flow and sealing.

• Unmatched Design Freedom: Easily create complex, proprietary flow field designs (serpentine, parallel, interdigitated) without the high cost or lead time of hard tooling. Ideal for rapid prototyping and optimization.

• Material Versatility for Harsh Environments: Process a wide range of alloys tailored for specific media, including stainless steel (316L), titanium, and aluminum, all with excellent corrosion resistance.

• Integrated Features: Etch channels, manifolds, ports, and alignment features in a single operation, ensuring perfect registration and reducing assembly steps.

• Lightweight & Efficient: Achieve thin walls between channels for compact, lightweight stack design with high thermal conductivity.

Flow Plate Applications

Our etched flow plates are critical parts in:

• Fuel Cells: PEMFC and SOFC bipolar plates for automotive, stationary, and portable power.

• Electrolyzers: Plates for PEM and alkaline water electrolysis systems (green hydrogen production).

• Heat Exchangers & Cold Plates: Microchannel plates for advanced thermal management in electronics, aerospace, and laser systems.

• Reactor Plates: For chemical processing and lab-on-a-chip devices requiring precise fluid control.

Our Advantages

• Speed from Prototype to Production: Rapid iteration of flow field designs without tooling, enabling faster development cycles and scaling to high-volume orders.

• Precision for Peak Performance: Consistent etching ensures uniform channel geometry across the entire plate, critical for even reactant distribution and system efficiency.

• End-to-End Control: From sourcing certified, high-purity metals to final surface treatment, we maintain stringent quality control for reliability in critical applications.

• Expert Collaboration: We work closely with engineers to optimize designs for manufacturability and performance, leveraging our extensive etching experience.

• Proven in Demanding Fields: Trusted supplier for components in cutting-edge energy, aerospace, and medical technology sectors.
