Dry-film lamination
Photoresist is applied uniformly to the prepared metal sheet.
Custom Etching Design
Precision chemical etching gives engineers the freedom to develop complex flow fields, revise designs quickly and move from prototypes to batch production without dedicated forming tools.

Why use chemical etching?
Chemical etching supports fast design changes, burr- and stress-free features, simultaneous channel formation and a flexible route from prototypes to batch production.
| Engineering factor | YIANTENG chemical etching | Stamping | Full CNC |
|---|---|---|---|
| Design changes | Update a digital phototool | Rework or replace the hard die | Revise program, fixture and toolpath |
| Prototype validation | Multiple variants can share one sheet | Production tooling precedes first parts | Each variant needs machining setup |
| Edge and stress | Burr- and stress-free | Burrs and forming stress may occur | Tool marks; deburring may be needed |
| Complex flow fields | All channels etched simultaneously | Complexity moves into die design | Features machined path by path |
| Cost profile | Low tooling; complexity has limited time impact | Higher upfront tooling; strong at stable high volume | Cost rises with setup and toolpath time |
How does a drawing become an etched component?
The design and processing route begins with the customer’s drawing and operating targets, then translates those requirements into a controlled etched structure.
Precision exposure
Digital artwork defines channels and features on both plate surfaces.
Simultaneous etching
Both sides are etched in one controlled process for balanced, repeatable geometry.
Inspection
Critical dimensions and surface quality are checked before release.
