How Does Chemical Etching Work:

The chemical etching method involves transferring a component pattern onto a light-sensitive resist material bonded to metal sheets. The unexposed portions of the photoresist are chemically stripped, baring the underlying metal surface that is then dissolved using etchant chemicals.

1. Meterial Selection: Material will be selected upon your request.
2. Material Cutting: Cutting material into the size needed.
3. Cleaning: Chemically clean the material.
4. Printing: Photosensitive resist is automatically coated on both sides of the material.
5. Drying: Dry all the water stains on the sheet
6. Exposure: The Photoresist is selectively removed to expose the metal.
7. Developing: The unexposed areas of resist are developed away to leave exposed metal areas.
8. Etching: The chemical etchant is sprayed onto the sheet, dissolving the exposed metal.
9. Stripping: Photoresist is removed to leave the metal parts.
10. Data Inspection: 100% inspeciton to meet the cutomer's need.
11. Packing: Dust-free packaging.

Why choose Chemical Etching?

1. High Accuracy: Achieve intricate and detailed digital designs that are not possible with traditional machining.
2. Flexibility: Easily accommodate design changes and modifications without the need for expensive tooling.
3. Material Efficiency:Save money by reducing waste and optimizing materials.
4. No Mechanical Stress:Maintain material integrity by avoiding mechanical deformation during etching.
5. Scalability: Efficiently scale from prototype to high-volume production.
6. Cost effective: Eliminates the need for expensive and time-consuming tooling
7. Rapid prototyping: Produce different designs at the same time without added effort.
