Water Transfer Technology of Vacuum insulated thermos stainless steel Insulation Cup
There are two kinds of water transfer technology, one is water mark transfer technology, the other is water drape transfer technology, the former mainly completes the transfer of text and photo patterns, the latter tends to complete the transfer of the entire product surface. Cubic Transfer uses a water-soluble film that is easily dissolved in water to carry pictures and texts. Because of the excellent tension of the water-coated film, it is easy to wrap around the surface of the product to form a graphic layer. The surface of the product is like spray paint to obtain a completely different appearance. The capping transfer technology can cover the color pattern on any shape of the workpiece, and solve the problem of three-dimensional product printing for the manufacturer. Surface draping can also add different patterns on the surface of the product, such as skin, wood, jadeite and marble, and can also avoid the common vacancy in color plate printing. And in the printing process, because the product surface does not need to contact with the printing film, it can avoid damage to the product surface and its integrity.
The basic technological process is as follows: 1) film printing: printing various patterns on polymer film; 2) spraying primer: vacuum insulated thermos stainless steel cups and bottles needs to be coated with an adhesive, that is, spraying primer. If you want to transfer different patterns, you must use different primers, such as brown, coffee, earthy yellow for wood grain, white for stone grain, and so on; 3) film extension: Let the film lay on the surface horizontally and wait for the film to stretch smoothly; 4) Activation: Activate the pattern of the transfer film into ink state with special solvents (activators); 5) Transfer printing: use water pressure to print the activated pattern on the vacuum insulated thermos stainless steel cups and bottles; 6) Wash: Wash the residual impurities of the printed workpiece with water; 7) Dry: Dry the printed workpiece, depending on the quality and melting point of the material. And; 8) spray paint: spray transparent protective paint to protect the surface of the printed object; 9) drying: dry the surface of the sprayed object.
Of course, the specific parameters need to be adjusted according to different situations.
Swell, Contigo brand stainless steel cups and bottles have achieved great success in sales by using water transfer printing and air transfer printing processes.
