1. Introduction to etching:Etching is a technique in which material is removed by chemical reaction or physical impact. Etching techniques can be divided into two categories: wet etching and dry etching. It was first used to manufacture printed embossed plates such as copper plates and zinc plates.

As early as the 1930s, people did use gold or silver to make hot stamping. Because its chemical properties are stable and it is not easy to oxidize in the air, use their good ductility to make it into a very thin metal foil by knocking and rolling

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

On April 8, 600 printing zinc plates were sent to Thailand customer.Etching process parameters of magnesium etching plateThe etching plate is a metal template for the printing industry (hot stamping). At present, there are mainly three kinds of etching plates of copper alloy, zinc alloy and magnesi

The hot stamping process uses the principle of hot press transfer to transfer the aluminum layer in the anodized aluminum to the surface of the substrate to form a special metal effect. Because the main material used for hot stamping is anodized aluminum foil
