Chemical etching doesn't bend or warp the material, so shims stay flat and maintain exact thickness across the entire part.
Clean edges without burrs mean parts fit properly without damaging sealing surfaces or adjacent components.
Etching provides consistent thickness to ensure proper spacing between parts.
The etching process doesn't compromise the base material's corrosion resistance properties.
We manufacture precision metal components in a wide range of forms and geometries, including:
✅ Flat Shims
✅ Formed Shims
✅ O-Ring Shims
✅ Custom Washers
✅ Spacers with Complex Geometries
✅ Half-Etched Components
✅ Parts with Micro Holes
✅ Shaped Electrodes

TMNetch is an industrial leader in the field of chemical etching. With over a decade of experience and global clients, we understand the nuances of manufacturing.
We etch thicknesses ranging from 0.03mm to 2.0mm across all metal alloys, providing options for various applications.
Unlike stamping, machining, or laser cutting, photochemical etching requires no expensive tooling. This keeps costs down and delivers burr free, smooth, clean surfaces.
We create U shapes, O rings, and other complex geometries difficult to achieve with traditional methods.
This process supports economical output for both prototypes and production volumes.
Tight tolerance control ensures consistent performance across batches and long production runs.
Stable processes support fast transition from sample validation to full scale manufacturing.
