Metal plate etching machine is a device that uses chemical reactions to perform metal etching. Its main principle is to use a specific acidic or alkaline solution to produce a chemical reaction on the metal surface to achieve a certain etching depth and shape. The application of metal plate etching

In etching processing, hydrochloric acid is an important additive potion. But how much is appropriate, this must have a benign understanding. Both acidity and acidity have a great influence on product quality. The amount of hydrochloric acid can be measured by the pH value. The following is the anal

Etching machines can be divided into chemical etching machines and electrolytic etching machines. In chemical etching, a chemical solution is used to achieve the purpose of etching through a chemical reaction. A chemical etching machine is a technology that removes materials by chemical reaction or

1. Alternative introductionLetterpress printing usually adopts copper plate and zinc plate, which is made by engraving or etching to make the required layout, but the quality of engraving layout is still different from that of etching plate. Therefore, the quality of the layout made by pre-coating

Etching is a technique that uses chemical reaction or physical impact to remove materials. Etching techniques can be divided into wet etching and dry etching.It was first used to manufacture copper plate, zinc plate and other printing embossing plates, and also widely used in the processing of weigh
