The etching process ensures that the metal plates are not only error-free but also stress-free when using them. Unlike the traditional EDM Wire Erosion and laser cutting methods, etching is a one-step process with accurate results done within a single operation.
The type of material you chose and the thickness desired determines the accuracy level attainable as you will be assured of +-0.010mm accuracy in most metals. Note customers specifications is a must consideration from the initial metal preparation and cleaning to the last inspection stage.
The etching on metal plate process. For maximum quality performance, a well laid down etching procedure is followed to ensure high quality end products are made for maximum customer satisfaction. Below is the etching process.
- Metal plate cleaning
- Metal plate preparation work
- Lamination of the metal plate
- Design and Artwork stage
- Printing and developing stage
- Finishing stage with the etching chemicals. Ferric chloride is widely used due to its ability to work excellently on both soft and hard substances and metals.
- Inspection and stripping stage.
Nickel Silver Etching.
There are numerous beneficial uses of the Nickel Silver metal, especially to the ability of this metal to resist corrosion and high heating effects. The metal is thus the best for making materials that are exposed to intense heating where corrosion wound set in instantly. Qualitech with the immense experience in metal plate etching will ensure that your Nickel Silver metal is well designed for whatever purposes and design you request.
Ranging from simple to intricate designs, with the use of the high cost-effective modern technology Nickel Silver etching has been made possible at Qualitech. The final products are error-free with the essential metal properties retained since a super accurate technology is embraced in the whole process.
Once the customer’s design is attained customer satisfied with it, cleaning of the raw Nickel-metal plates must be done to ensure that high quality is achieved since dirt on the surface of the metal can compromise the much-desired quality.
The next etching on metal plate involves covering/coating the Nickel sheet with a UV penetrating photo-resist, thus ensuring that printing is only done on the desired part of the layer. Printing is then done on the resistant material, therefore covering only the required section.
The materials are then passed through some chemical bath, usually, the ferric chloride since it is the most suitable for both the soft and hard metals etchant material. By this time the content has already etched away, thus cutting your desired profile has already taken place.
For quality assurance, any traces of ferric chloride and photo resistant particles remaining are removed after the whole process comes to an end. A team of quality assurance technicians then does quality testing and approval before handling the finished product to our clients.
The high technology embraced has made it possible for large scale processing with a lot of efficiencies; thus, our customers receive their final products within the minimum time possible. Accuracy is guaranteed, and you can get more information by contacting Qualitech customer services on 01354 658787.
