First, the definition of stamping
Bronzing, scientific name anodized hot stamping, with in certain pressure and temperature, the metal foil or pigment foil to print or other substrate on the way, said foil stamping processing, commonly known as gilding. It is often said that the stamping of multi - refers to the hot stamping of electronic materials.
Two, hot stamping principle
The essence of hot stamping is the transfer, is the above picture through the heat and pressure of the role of transfer to the substrate above the technical process.
When plate followed the report of the soleplate of the electric heating to a certain extent, across the anodized film and paper embossing, effect of using temperature and pressure, the attached on the polyester film glue layer, a metal aluminium layer and chromatographic transfer to paper.
Three, hot stamping equipment
Can be used for the hot stamping material of electronic aluminum foil stamping to the printing machine is known as hot stamping machine.
Types and characteristics of A. hot stamping machine
According to the stamping method is divided into:
Flat hot stamping, the way for the plane surface of Linping.
Applanation, the short-run way for the hot wheel on the plane.
Round press circle, its hot stamping method for hot stamping roll on pressure roll.
According to the degree of automation: manual, semi-automatic, fully automatic.
According to the whole method: vertical, horizontal.
B. hot stamping machine root tissue
Body frame, including the shape of the body and the paper, paper folding, etc..
Hot stamping equipment, including electric heating plate, hot stamping, embossing plate and bottom plate. Electric hot plate fixed on the printing plate platform, electric heating plate is arranged in the power of 600 - 250OW roundabout type electric heating wire; short-run version is corrosion of copper, or zinc plate is characterized in that heat transfer is good, not easy to deformation, pressure resistance, abrasion resistance; nano imprint lithography version generally aluminum or iron edition; the bottom of the aluminum sheet with thickness of about 7 mm for posting the short-run version of;
An electro chemical aluminium conveying device is composed of a roller, a feeding roller and a feeding roller, an electro chemical aluminum rolling roller and a feed structure. Anodized aluminum were loaded on the reel on, hot stamping anodized in two send roll through, composed of a cam, a connecting rod, a ratchet wheel, a ratchet pawl send sucked into to an organization shares move sent the scrolls of the intermittent tumbling, send volume and intermittent tumbling, femoral artery and anodized aluminum feed, feed interval set for the length of the hot stamping pictures. After hot stamping, electro chemical aluminum roll on roll.
Four, hot stamping material
According to the data type can be divided into: anodized hot stamping, foil stamping, color film, foil stamping and other hot stamping foil stamping. The following key introduce hot stamping anodized aluminum materials, aluminum foil is a film based on the vacuum vapor plating a layer of metal foil made hot stamping data.
1. The first layer is the basement membrane layer, also known as the bottom sheet, it plays the role of supporting the other layers of the thickness of 12, 16, 18, 20, 25 u polyester film or polyester.
The second layer is the insulating layer, easy to basement membrane and sized aluminum foil.
The third layer is the dyeing layer: the supply of a variety of color effect, together with the maintenance of aluminum.
The fourth layer is the aluminized layer: the reflection of light, metal luster, selection of vacuum aluminum method. With principle is coated with pigment film, placed in a vacuum aluminum plating machine within the vacuum chamber one after another, under a certain vacuum degree, after heating resistance, aluminum wire melting and successive chromatography evaporate into thin films, they formed the aluminized layer.
The fifth layer is the adhesive layer, the aluminized layer is glued to the paper substrate. Aluminum foil mainly to gold and silver, with magnificent scenery, beautiful color and luster, crystal bright dazzling, easy to use features, is suitable for printing on paper, plastic, leather, coating cloth, organic glass, plastic and other materials, is a modern hot stamping is the most commonly used a kind of data
