Chemical Etched PCHE Plates for Hydrogen & High Pressure Heat Exchangers
Product Overview
Xinhaisen specializes in manufacturing high-precision Etched PCHE Plates using advanced Photo Chemical Machining (PCM) technology. Our chemical etching process produces complex microchannel structures with exceptional dimensional accuracy, burr-free edges, and stress-free surfaces, making it an ideal solution for Printed Circuit Heat Exchangers (PCHEs).
PCHE plates are widely used in industries requiring compact, highly efficient, and high-pressure heat transfer systems. Compared with conventional machining, chemical etching enables intricate microchannel geometries without tool wear or mechanical deformation.

Engineering Partnership: We work closely with clients to customize the PCHE design for their specific thermal, mechanical, and material challenges
Frequently Asked Questions
Q1: What is the advantage of using etched plates over machined plates for PCHE?
A: Etching produces burr-free, stress-free, and uniformly smooth channels without heat-affected zones. It also allows for much finer channel geometries (as small as 0.03mm) than traditional machining, and design changes are quick and inexpensive since no hard tooling is required.
Q2: What materials can you etch for PCHE plates?
A: We can etch stainless steel (SUS304, SUS316, SUS316L), titanium (Gr1, Gr2), Inconel, Hastelloy, copper, brass, and many other alloys commonly used in high-performance heat exchangers.
Q3: What is the minimum channel width you can achieve?
A: We can achieve channel widths as small as 0.03mm and ridge (wall) widths down to 0.015mm, depending on material thickness.
Q4: What is your typical lead time for PCHE prototype plates?
A: Prototype samples typically take 3-7 working days after design approval. Mass production lead times are 7-15 working days, with expedited options available for urgent orders.
Q5: Are your etched plates ready for diffusion bonding?
A: Yes. Because etching produces clean, burr-free, oxide-minimized surfaces, our plates are ideal for direct diffusion bonding or welding without additional surface preparation.
