The application of heat transfer and water transfer technology

the printing method of transferring the graphics and texts on the intermediate carrier film to the substrate by corresponding pressure is called transfer printing. According to the different pressure, transfer printing is divided into: heat transfer, water transfer, air transfer, silk transfer, low temperature transfer, etc

I Heat transfer printing technology

heat transfer printing is a technology that prints the pattern of the ink layer on the heat-resistant adhesive tape, and prints the pattern of the ink layer on the finished material by heating and pressurizing. Even for patterns with multiple colors, since the transfer operation is only a process, customers can shorten the printing pattern operation and reduce the loss of materials (finished products) caused by printing errors. Using heat transfer film printing, multi-color patterns can be mapped at one time, without chromaticity, and simple equipment can also print realistic patterns

heat transfer equipment is used to decorate aluminum shapes and various metal plates, which can achieve the effect of wood products or marble. The heat transfer equipment works according to the principle of thermal sublimation. It can quickly transfer the required wood grain or marble grain to the surface of aluminum powder coating in minutes and penetrate into the micron inside the coating. Aluminum transfer production process: first, use the film machine to roll and cut the heat transfer film to the required size. The second is to use the transfer ultrasonic packaging machine to weld the cut transfer film into a workpiece wrapping bag with ultrasonic wave according to the size of the workpiece. Third, insert the worker into the workpiece wrapping bag made of transfer film on the packaging platform. Fourth, put the workpiece wrapped with the transfer film on the trolley platform of the heat transfer machine, and 18 aluminum materials can be placed in turn. Connect and lock the vacuum taps on both ends of the aluminum material, and turn on the vacuum switch. At this time, the transfer film is tightly attached to the aluminum material. The trolley will automatically send the aluminum materials to the baking oven. The baking oven will automatically raise the temperature by 220 degrees and keep the temperature for 3 minutes. The trolley will automatically exit the baking oven. Fifth, loosen the vacuum tap and remove the workpiece. Sixth, remove the transfer film and check the quality of the workpiece

lithographic heat transfer production process: first, use the film cutter to cut the heat transfer paper roll into the required size. The second is to attach the heat transfer paper film to the surface of the workpiece and put it on the plate heat printer. Third, push the flat plate to the heating area of the flat plate heat transfer machine, press the pressing plate switch, and the pressing plate will press the heat transfer paper tightly on the workpiece, heat it and keep it warm for one minute. Fourth, raise the pressing plate, push the workpiece to the part section, remove the transfer film, remove the workpiece and check it

heat transfer technology is widely used in electrical appliances, daily necessities, building materials and decoration. Because it has the properties of corrosion resistance, impact resistance, aging resistance, wear resistance, fire resistance, and no discoloration after being used outdoors for 15 years, almost all goods are made in this way. For example, when you open the shell, you can see a dense number of labels with bar codes inside. Many labels are required to withstand the test of time, not deform and fade for a long time, not wear out due to contact with solvents, not deform and change color due to high temperature, etc., so it is necessary to use a special material printing medium and printing material to ensure these characteristics, which can not be achieved by general inkjet and exciting printing technology

water transfer printing technology

is known as a relatively environmentally friendly technology, and it is also the most emerging efficient printing production at present, which is probably related to its separation from the ink in the printing process. Water transfer uses water pressure and problems such as zero down payment, low threshold of leasing companies, blind acquisition, insufficient treatment of 2-hand equipment, and small agricultural engineering machinery enjoying government subsidies. Activators dissolve and transfer the stripping layer on the water transfer carrier film. The basic process is as follows: 1) film printing: Print various patterns on the polymer film; 2） Primer spraying: many materials must be coated with a layer of adhesive, such as metal, ceramics, etc. if you want to transfer different patterns, you must use different ground colors. For example, the wood grain basically uses brown. As an important raw material for cars, the price of steel and aluminum is rising, coffee, khaki, etc., and the stone grain basically uses white, etc; 3） Membrane extension: let the membrane lie flat on the water surface and wait for the membrane to extend smoothly; 4） Activation: activate the pattern of the transfer film into an ink state with a special solvent (activator); 5） Transfer: use water pressure to print the activated pattern on the printed object; 6） Water washing: wash the remaining impurities of the printed workpiece with water; 7） Drying: dry the printed workpiece, and the temperature depends on the simplicity and melting point of the material; 8） Spray finish paint: spray transparent protective paint to protect the surface of the printed object; 9） Drying: dry the surface of the object sprayed with finish paint

there are two kinds of water transfer technology, one is water mark transfer technology, and the other is water drape transfer technology. The former mainly completes the transfer of words and photo patterns, while the latter tends to complete the transfer on the whole product surface. Cubic transfer uses an aqueous film that is easily dissolved in water to carry graphics and texts. Due to the excellent tension of the water coating film, it is easy to wrap around the product surface to form a graphic layer that will reduce the quality of the hydraulic oil, and the product surface will get a different appearance like painting. Drape transfer technology can drape color patterns on workpieces of any shape, and solve the problem of three-dimensional product printing for manufacturers. The curved surface coating can also add different lines on the product surface, such as leather, wood, emerald and dolomite, and can also avoid the void often seen in general board printing. And in the printing process, because the product surface does not need to contact with the printing film, it can avoid damaging the product surface and its integrity. (text/Yu Lixuan)
