2. Photochemical machining - Wikipedia

   en.wikipedia.org/wiki/Photochemical_machining

   In general, steel, copper or aluminium workpieces with a thicknesses up to 0.020 in (0.51 mm), part costs will approximate $0.15–0.20 per square inch. As the geometry of the part becomes more complex, photochemical machining gains greater economic advantage over sequential processes such as CNC punching, laser or water-jet cutting, and ...

3. Photoengraving - Wikipedia

   en.wikipedia.org/wiki/Photoengraving

   A print made in 1907 from a photoengraved plate. It reproduces a sketch of Parga's castle made by Ludwig Salvator.. Photoengraving is a process that uses a light-sensitive photoresist applied to the surface to be engraved to create a mask that protects some areas during a subsequent operation which etches, dissolves, or otherwise removes some or all of the material from the unshielded areas of ...

4. Chemical milling - Wikipedia

   en.wikipedia.org/wiki/Chemical_milling

   A high-purity (≥99.9998%) aluminium bar that has been etched to reveal the component crystallites. Chemical milling or industrial etching is the subtractive manufacturing process of using baths of temperature-regulated etching chemicals to remove material to create an object with the desired shape. [1][2] Other names for chemical etching ...

5. Roller printing on textiles - Wikipedia

   en.wikipedia.org/wiki/Roller_printing_on_textiles

   Roller-printed cotton cushion cover panel, 1904, Silver Studio V&A Museum no. CIRC.675–1966 Indigo Blue & White printed cloth, American Printing Company, about 1910. Roller printing, also called cylinder printing or machine printing, on fabrics is a textile printing process patented by Thomas Bell of Scotland in 1783 in an attempt to reduce the cost of the earlier copperplate printing.

6. Etching - Wikipedia

   en.wikipedia.org/wiki/Etching

   ferric chloride may be used for etching copper or zinc plates, whereas nitric acid may be used for etching zinc or steel plates. Typical solutions are 1 part FeCl 3 to 1 part water and 1 part nitric to 3 parts water. The strength of the acid determines the speed of the etching process. The etching process is known as biting (see also spit ...

7. Rotogravure - Wikipedia

   en.wikipedia.org/wiki/Rotogravure

   Rotogravure (or gravure for short) is a type of intaglio printing process, which involves engraving the image onto an image carrier. In gravure printing, the image is engraved onto a cylinder because, like offset printing and flexography, it uses a rotary printing press. Once a staple of newspaper photo features, the rotogravure process is ...

8. Etching (microfabrication) - Wikipedia

   en.wikipedia.org/wiki/Etching_(microfabrication)

   Etching (microfabrication) Etching tanks used to perform Piranha, hydrofluoric acid or RCA clean on 4-inch wafer batches at LAAS technological facility in Toulouse, France. Etching is used in microfabrication to chemically remove layers from the surface of a wafer during manufacturing. Etching is a critically important process module in ...

9. Photoresist - Wikipedia

   en.wikipedia.org/wiki/Photoresist

   Anti-etching is the ability of a photoresist to resist the high temperature, different pH environment or the ion bombardment in the process of post-modification. Surface tension In order to better wet the surface of substrate, photoresists are required to possess relatively low surface tension.
