The role of stunner

The corona treatment machine is a kind of electric shock treatment, which makes the surface of the substrate have higher adhesion. The principle is to use high-frequency and high-voltage corona discharge on the surface of the plastic to be processed (high-frequency AC voltage is as high as 5000-15000V/m2), and low-temperature plasma is generated, which causes radical reaction on the surface of the plastic and crosslinks the polymer. 

The surface becomes rough and its wettability to polar solvents is added. These ionic bodies are damaged by electric shock and penetrate into the surface of the printed body to damage its molecular structure, thereby oxidizing and polarizing the processed surface molecules, and ion electric shock corrodes the surface. So as to increase the adhesion ability of the surface of the substrate.

Yuantong Technology always keeps up with the development of the packaging machinery and equipment market, continuously introduces modern production equipment and advanced manufacturing technology at home and abroad, actively absorbs design elements and experience in the field of packaging machinery at home and abroad, and continues to expand the category of professional machinery and equipment. The packaging machinery and equipment series, mold manufacturing series, automation series, development software series, research and development series, and packaging series produced and sold today have been deeply recognized by the market for their high quality and brand quality.
