Stainless Steel Etching
Photo etching stainless steel refers to corrode the stainless steel sheet by the chemical way, using the strong oxidizing property of ferric chloride to etch out various kinds of shapes and patterns. According to the purpose can be divided into half etching and etching through with different depth and degree. The main principle of photo chemical etching of stainless steel is to cover the areas that do not need to be corroded with photosensitive ink, and expose the areas that need to be corroded, and use chemical solutions to corrode the unnecessary parts.
Stainless steel is a corrosion-resistant metal so that the chemical reagents used in the photo etching stainless steel process will not affect the performance of the metal. Photo etching stainless steel can not only keep the smooth and scratch-free surface of metal parts but also has high precision and tight tolerance. For custom metal parts, stainless etching is an ideal etching process.
The basic process of stainless steel etching
- Pre-treatment of raw materials, including degreasing, polishing, wire drawing.
- Redesign the stainless steel plate according to the requirements of customers, including expose the corrosive area and protect the non-corrosive area.
- The photo etching stainless steel process, using the strong oxidizing property of ferric chloride to etch out various kinds of shapes and patterns.
- Remove the version, remove the photosensitive film of the non-corrosive area.
- In the last process, clean the sheet and cover some protective film to protect the stainless steel sheet.
Benefits of Stainless Steel Etching
Metal etching stainless steel can provide very high productivity. Once the film is finished, which can be reused for mass production several times, mass production can be completed in a few hours.
Half-etching and etching through can be finished in one sheet, which is easy to add a logo and some other special shapes.
Almost all metals with different structures and thicknesses can be etched, and there are no restrictions on various pattern designs.
No burrs and pressure points
No burr. No pressure point. No deformation. Photo etching stainless steel does not change the material properties and does not affect the function of the products.
High precision and tight tolerance
The metal parts made of stainless etching have high precision and tight tolerance. Tolerance The tolerance of customized metal parts can be controlled within 0.03mm, micropore diameter can be 0.03mm, wire diameter can be 0.015mm, uniformity can be +/-0.03mm.
Low-Cost and Fast speed
TMN stainless steel photo etching process has fast and speeds research and development, low development cost, and convenient to modify the design drawing. No need to make expensive molds, photo chemical etching processing only needs to make the film to complete the prototype design, which will not change the metal properties due to heat or mechanical stress during the processing.
