Precision Etched Metal Flow Plates for Fuel Cells & Heat Exchangers with Complex Micro Etching
Flow Plates Overview
Xinhaisen Technology is a leading manufacturer of high-precision etched flow plates used in injection molding, die casting, and industrial fluid distribution systems. Our chemically etched flow plates ensure ultra-smooth material flow, minimal pressure loss, and extended tooling life compared to conventional machined alternatives.
Our primary manufacturing method is Precision Chemical Etching, which is ideal for creating complex, burr-free channels without inducing mechanical stress or deformation in the metal.
Flow Plates Features
Complex Design Capability: Easily produce intricate, multi-level channel geometries that are difficult or expensive with traditional machining.
Burr-Free Channels: Etching ensures smooth, clean fluid pathways, preventing clogging and minimizing pressure drop.
Superior Flatness & Uniformity: Excellent for sealing in stackable systems like fuel cells or heat exchangers.
Material Integrity: Stress-free processing preserves the metal's inherent properties, such as corrosion resistance and thermal conductivity.
Rapid Prototyping: Go from design to functional prototype in days, not weeks.

FAQ
Q1: What's the advantage of etched flow plates over machined ones?
Etched plates provide smoother channels, no burrs, and better wear resistance at lower cost for complex designs.
Q2: Can you produce conformal cooling channels?
Yes! We specialize in 3D cooling channels that follow mold contours for optimal thermal management.
Q3: What's your lead time for prototype runner plates?
5-7 working days after design approval (faster than CNC machining).
