Surface Treatment Processes and Equipment
Surface treatment is essential for preparing the stainless steel surface and achieving the desired finish. Here are recommended surface treatment processes and equipment:
| Equipment Name | Estimated Price | Usage Description | Manufacturer | Manufacturer Website |
|---|---|---|---|---|
| Grinding machine (Automatic) | $140,000 | Used to grind the stainless steel surface, ensuring a smooth and uniform finish before engraving. | Dragonetching | www.dragonetching.com |
| Grinding machine (Manual) | $70,000 | Provides a manual grinding option for smaller batches or specialized applications. | Dragonetching | www.dragonetching.com |
Selection of Stainless Steel Engraving Solutions
Engraving stainless steel using chemical solutions involves careful selection of etchants. The choice depends on the specific application and desired engraving characteristics. Here are some commonly used etchants for stainless steel:
- Copper Chloride (CuCl2) Engraving Solution: Effective for stainless steel, copper chloride provides a controlled engraving rate and is commonly used for detailed and intricate designs.
Stainless Steel Grades and Engraving Parameters
The table below lists different stainless steel grades, along with their engraving parameters and estimated results. All samples have the same thickness, width, and length for uniform comparison.
| Stainless Steel Grade | Chemical Engraving Temperature (°C) | Chemical Engraving Solution Concentration (%) | Estimated Chemical Engraving Depth (µm) | Chemical Engraving Quality |
|---|---|---|---|---|
| 304 | 45 | 40 | 20 | High |
| 316 | 45 | 40 | 18 | High |
| 430 | 45 | 40 | 22 | Medium |
| 201 | 45 | 40 | 25 | Medium |
| 410 | 45 | 40 | 15 | High |
Screen Printing Engraving Process
The stainless steel engraving process involves several detailed steps to ensure precision and quality:
Cleaning
- Step: Clean the stainless steel surface using the cleaning line.
- Detail: This step removes all contaminants, ensuring the stainless steel is ready for further processing.
Screen Printing
- Step: Apply resist paint using the screen printing line.
- Detail: The screen-printed resist protects areas of the stainless steel that should not be engraved.
Drying
- Step: Dry the resist-covered stainless steel using the drying line.
- Detail: This ensures the resist is firmly adhered to the stainless steel surface.
Developing
- Step: Develop the screen-printed stainless steel using the developing line.
- Detail: This removes the unexposed resist, revealing the areas to be engraved.
Engraving
- Step: Engrave the stainless steel using the stainless steel engraving line with the selected engraving solution.
- Detail: The engraving solution removes the exposed stainless steel, creating the desired pattern.
Stripping
- Step: Remove the remaining resist using the stripping line.
- Detail: This leaves behind the final engraved stainless steel pattern, ready for any further processing.
