Precision Metal Parts with Photochemical Machining
A specific type of metal etching, photochemical machining—also known as photo etching—is the ideal way to economically produce complex parts with fine detail. Fundamentally, photo etching is similar to other types of metal etching. A coating is applied to a sheet metal surface, and acid is used to dissolve away exposed areas.
Unlike other etching methods, however, photo etching involves the use of hardened photographic film. The film shows the negative image of the part to be created, and two identical sheets are applied to the front and back of the sheet metal. That assembly is then laminated with a UV-sensitive photoresist, which hardens only around the clear areas of the film. The outlines of the parts are left unprotected by the resist, and when the assembly is bathed in an acidic solution, that outlining material is washed away, leaving only the parts of interest.
A Brief History of Metal Etching
Metal etching first emerged as a sheet metalworking technology over 50 years ago. The earliest applications of the technique were rooted in the artisan space—examples of which include Rembrandt etchings and engravings for medieval swords.
While many people continue to view metal etching in this light, the use of the technology has grown rapidly in the last decade. Designers are now leveraging this highly precise corrosion process to solve a number of engineering challenges that are not possible to overcome or become too costly with the traditional route of stamping. This is paving the way for advanced aircraft, low to no emission vehicles and satellite communications, amongst other applications.
Etching lid seam welding process & assembly enhance
WinWay lids are composed of Kovar, steel and other alloys, and are used in the seam welding process to melt and fuse the thinner edges of the lids onto a metal seal ring. This concentrates the greatest heat at the perimeter of the lid to enable a weld onto the metal seal ring.
Industrial metal etching
Industrial metal etching is a metal manufacturing method that uses an acid bath to subtract material and form the desired shape. Generally, the industrial metal etching process involves five steps: cleaning, masking, graffiti, etching and decontamination

Frequently Asked Question
Do you have any question?
Etching technology is divided into wet etching and dry etching
Metal etched lid is mainly used for communication box shielding
Processing area: The processing area of stainless steel parts should be relatively fixed. The platform of the stainless steel processing area should be isolated with rubber pads. The stainless steel parts processing area should avoid damage and pollution to the stainless steel parts. Cutting: The cutting of stainless steel parts adopts shearing or plasma cutting, sawing and so on. Machining: The stainless steel parts should also be protected during machining such as turning and milling, and the oil stains, iron filings and other sundries on the surface of the workpiece should be cleaned when the work is completed. Forming and adding workmanship: Effective measures should be taken to avoid scratches and creases on the surface of stainless steel parts during the process of rolling and bending of the head.
