Description

Automatic gilding press

Technical Field

The invention belongs to the technical field of stamping machines, and particularly relates to an automatic stamping machine.

Background

The gold stamping process uses the principle of hot pressing transfer to transfer an aluminum layer in the alumite onto the surface of a printing stock to form a special metal effect, and the main material used for gold stamping is alumite, so gold stamping is also called alumite hot stamping. Galvanic aluminum foil is typically composed of multiple layers of material, often P E as a substrate, followed by release coatings, color coatings, metal coatings (aluminizing) and glue coatings.

The hot stamping basic process is that under the pressure state, namely the state that the alumite is pressed by a hot stamping plate and a printing stock, the alumite is heated to melt a hot-melt organic silicon resin layer and a glue agent on the alumite, at the moment, the viscosity of the heated and melted organic silicon resin becomes small, and the viscosity of the special heat sensitive adhesive is increased after the heated and melted organic silicon resin is heated and melted, so that the aluminum layer and the alumite-based film are peeled off and transferred onto the printing stock. With the pressure removed, the adhesive is rapidly cooled and solidified, and the aluminum layer is firmly attached to the printing stock, thus completing a hot stamping process.

In the process of cosmetic packaging bottles, the additional value of the surface product is improved. The gold stamping processing is a common processing mode, and can further show strong decorative effect of the product.
