1. The traditional artificial corrosion is carried out by flowing back and forth through the etching liquid and chemically reacting with the metal surface to achieve corrosion. The speed of manual etching is very slow, the etching precision is low, the syrup is exposed to the air, and the workshop has a large taste and cannot be mass-produced.

2. The working principle of the horizontal etching machine is to spray the etchant evenly on the surface of the product by means of high-pressure spraying to achieve the corrosion effect. Xin Hengli hardware etching machine body is not less than 12mmPP/PVC sheet, the whole machine adopts double-layer tempered glass seal inside and outside, which can effectively guarantee the working environment of the workshop; the built-in titanium alloy heating tube and titanium alloy water-cooled tube can effectively control the syrup temperature. The sprinkler system uses an independent swing quick-release spray frame to ensure the uniformity of etching and to facilitate the cleaning of the nozzles later.
