Product Description
Custom Etched Flow Channel Plates Metal Etching Service 0.5-5.0mm Thickness for Heat Exchangers
Service Overview
This page covers our photochemical etching service for flow channel plates used in heat exchangers and other compact thermal assemblies. It is not a fixed catalogue part: each plate is produced from a customer drawing, so you supply the channel layout, plate outline, material grade and thickness, and we etch that pattern into the metal sheet. Double-sided etching is used whenever channels are required on both faces.
The service is aimed at engineers who need fine, repeatable channel geometry, burr-free surfaces and a flat plate that is ready for downstream bonding, brazing or welding.
What This Etching Service Covers
- Etching of serpentine, parallel and pin-fin style flow channels
- Channel plates, cover plates and manifold plates for plate-type heat exchangers
- Microchannel patterns for compact and diffusion-bonded assemblies
- Metal etching work for nameplates, shims, screens and encoder discs
- Prototype lots and repeat production from the same tooling-free process
Materials We Etch
- Stainless steel: SUS304, SUS316, SUS316L
- Titanium: Gr1, Gr2
- Nickel alloys: Inconel, Hastelloy
- Copper, brass and other etchable alloys on request
Material certificates can be issued with the shipment when they are specified on the purchase order.

Quality Control
- Incoming material verified against the ordered grade and thickness
- First-article dimensional inspection before the run continues
- Channel width, depth and plate flatness checked on sampled parts
- Visual inspection for burrs, stains and etch defects
- Optional inspection report and material certificate with the shipment
- Production under ISO 9001, ISO 14001 and IATF 16949 certified systems
How an Order Is Handled
- You send the 2D drawing, material grade, thickness and estimated quantity.
- Our engineers review etchability and confirm the process route, or return marked-up drawings where changes are needed.
- Quotation, sample arrangement and schedule are agreed in writing for your specific project.
- Production is released after drawing approval, with inspection records prepared alongside the parts.
- Parts are packed and shipped as stated on the order confirmation.
Frequently Asked Questions
Why use chemical etching instead of machining for flow channel plates?
Etching removes metal without mechanical force or heat-affected zones, so the plate stays flat and the channels stay burr-free. There is no hard tooling, which means a drawing revision needs a new film rather than a new die.
Can both sides of a plate be etched?
Yes. Double-sided etching is used for plates that need channels on both faces, and front-to-back registration is held through the same phototool set.
What drawing information do you need?
A dimensioned 2D drawing in DXF, DWG, CAD or PDF, plus the material grade, sheet thickness, quantity and any flatness or surface requirement.
How is the schedule decided?
The schedule is set per project once the drawing is reviewed and the order is confirmed. It varies with channel complexity, material availability and quantity, and is written on the order confirmation.
Are the plates ready for bonding?
Etched surfaces are clean and free of burrs and oxide scale, which suits diffusion bonding, brazing and welding. Any extra surface preparation should be specified on the drawing or purchase order.
