What are the technical requirements for bronzing?

First of all, the technical requirements of bronzing largely depend on the early appearance of the product design. For example, the appearance and design of cosmetic bottles and face cream pump bottles will have an impact on the technical requirements of bronzing.

Secondly, different device parameters are set differently.

(1) The temperature of hot stamping

The factors that should be considered to determine the best hot stamping temperature are the type and performance of materials, hot stamping pressure, hot stamping speed, hot stamping area, hot stamping text structure, printing background ink layer color, thickness, area, hot stamping workshop room temperature.

(2) Pressure for hot stamping

The role of pressure is to ensure that the anodic oxidation can adhere to the substrate, the anodic oxidation of the bronzing part of the shear. The factors that affect the setting of hot stamping pressure include hot stamping temperature, production speed, anodic oxidation performance and the surface of the hot material. For example, aluminum bottles and soft tubes, materials are different, stamping pressure is different.

(3) The speed of hot stamping

Hot stamping speed determines the contact time of anodized and substrate, contact time and hot stamping fastness is proportional under certain conditions.

Finally, the choice of gold leaf.

(1) Metal foil: Metal foil has good ductility and a specific luster, such as gold, silver, copper, aluminum, etc.

(2) foil: foil hot stamping temperature is low, the printing base material adaptability is not strong.

(3) electrochemical aluminum foil: anodized hot stamping foil, generally composed of five layers of different materials, from the back to the front in turn for the base film layer (also known as the sheet base), isolation layer (also known as the detachment layer), protective layer (also known as the color layer), aluminum layer and adhesive layer.

(4) composite foil: composite foil is no isolation layer, adhesive layer, and directly foil film base, dyeing layer and aluminum plating layer combined as one of the hot stamping material.

(5) holographic hot stamping foil: holographic hot stamping foil is a thin film foil with hot stamping function for holographic laser processing.

In our daily life, we can see gold stamping almost everywhere. For example,foaming pump bottles, lotion pump bottles, lipgloss tubes. These perfect bronzing effect mainly depends on the temperature, pressure and bronzing speed of the three mutually compatible level.
