plating Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. It is a process that uses electrolysis to make a metal film on the surface of a metal or other material to prevent it. Metal oxidation (such as rust), [...]
Adsorption Adsorption is an interface phenomenon, which is the phenomenon in which atoms and molecules of one substance attach to the surface of another substance. The phenomenon that the ink is fixed on the paper surface during the printing process is an adsorption phenomenon. Absorption is also an interface phenomenon. Absorption occurs if the atoms [...]
UV ink, also known as ultraviolet drying ink, refers to ink that can change from a liquid state to a solid state under the irradiation of a certain wavelength of light. UV lithography refers to a printing method that applies UV inks and various auxiliary materials to lithographic offset printing presses, uses cross-linking polymerization under [...]
Introduction: Convex embossing, a special process technology in the surface finishing of printed materials. The use of uneven embossing can make printed products have a three-dimensional effect, and the overall structure also has rich levels, adding more and more intense artistry. And it is an environmentally friendly process, and its production process is free of [...]
The essence of hot stamping / hot stamping is transfer, which is the process of transferring the pattern on anodized aluminum to the substrate by heat and pressure. When the printing plate is heated to a certain degree with the attached electrothermal master plate, it is embossed through the anodized aluminum film and paper, and [...]
I. Introduction of ABS Chinese name: ABS plastic English name: Acrylonitrile Butadiene Styrene plastic Chemical name: acrylonitrile-butadiene-styrene Molecular formula: (C8H8 · C4H6 · C3H3N) n (but it is often a graft polymer containing butadiene and Mixture of acrylonitrile-styrene copolymer) Structural formula: Melting point: 217 ~ 237 ° C (thermal decomposition temperature is above 250 ° [...]
definition Hot stamping process: It is a process in which metal foil is transferred to the surface of printed matter or other articles by hot pressing to increase the decorative effect. Cold bronzing process: It is a process that transfers metal foil to the surface of printed matter or other articles with no effect of [...]
plating 1. The concept of electroplating is to plate one or more metal layers on the surface of the workpiece by electrodeposition to give the workpiece a beautiful appearance or specific functional requirements. During electroplating, the plated metal or other insoluble material is used as the anode, and the metal product to be plated is [...]
The surface pretreatment of plastic products mainly includes coating coating treatment and plating coating treatment. Generally, the crystallinity of plastic is large, the polarity is small or non-polar, and the surface energy is low, which will affect the adhesion of the coating. Since plastic is a non-conductive insulator, it cannot be coated directly on the [...]
Water transfer definition A transfer method in which the graphic ink layer and the substrate on the transfer material are separated by means of water during transfer. Classification According to the characteristics of the transfer, it is divided into water mark transfer and water-covered transfer. The former mainly completes the transfer of text and photo [...]
