One of the core components of Sublistar transferencia de calor por sublimación is the heating plate. Therefore, pay attention to the heating plate when choosing a sublimation heat transfer machine. The upper and lower plates shall be made of aluminum, and the heating pipes shall be cast aluminum. If the grooves are engraved on the aluminum plate and then adhered to the aluminum plate with a heating pipe, unnecessary energy loss will be caused, and the use of this device may lead to the disadvantages of the slow rise and large temperature difference. If the lower plate is made of an iron plate or other materials, it will work for a long time under high temperatures and high-pressure environments and be easily deformed. The upper plate of the ironer should be parallel to the lower plate. If the upper and lower blocks are tightly sealed, you can place cardboard or other rigid material on the four corners and press down on the handle. After sealing and clamping the upper and lower wooden blocks, pull out the cardboard, and you can see the upper and lower blocks. It doesn’t matter whether the board is flat or not, or whether the sublimation heat transfer is qualified.
In the long history of dye sublimation transferring manufacturer development, there has been a set of scientific, reasonable, and applicable standard measurement methods for the continuous summarization, extraction, and application of sublimation transfers. Due to time and space constraints, here is a simple repetition. This article briefly introduces the classification of dye sublimation printers for t-shirts: At present, the stamping methods of sublimation printers for t-shirts are divided into two types: flat-pressing sublimation printers and circular-pressing sublimation printers. The methods of pressure transmission are divided into hydraulic, pneumatic, and mechanical ones. Flat pressing types (hydraulic, pneumatic, and mechanical) are usually used for small batches and small areas of dye sublimation transfer. These devices have their advantages, and the current test results are simple. The single order is: mechanical sublimation heat transfer is better than hydraulic heat transfer, hydraulic one is better than pneumatic one; both mechanical and hydraulic t-shirt sublimation printers are relatively stable, generally small batch processing or testing. It is recommended to use hydraulic sublimation printers for heat transfer; if the user is mass production, it is recommended to use CI. The stability of the pneumatic hot stamping machine and mechanical heat transfer machine is second only to the other two.
La estampado en caliente temperature depends on the hot stamping machine, hot stamping film, and hot stamping material. A higher or lower hot stamping temperature should be blindly pursued, and the hot stamping temperature should be determined according to the effect after hot stamping. The hot stamping pressure must be adjusted to the most suitable level. Otherwise, it will be too large, which will easily damage the head and burn, and if it is too small, it will affect the hot stamping effect. After adjusting to the hot stamping pressure, the pressure should be adjusted and locked so as not to change mass production. The punching time (speed) should be determined according to the specific punching material. The faster the stamping speed, the higher the production efficiency. However, due to some special circumstances, some products have to use slow hot stamping.
Thermal transfer printing is a special printing process that has been used in foreign countries for more than 20 years. The printing method is divided into two parts: transfer film printing and transfer processing. The transfer film printing adopts screen printing (resolution up to 300 dpi), the film surface is pre-printed, the film surface is printed with rich patterns, bright colors, small color difference, good reproducibility, and can meet the designer’s requirements, suitable for mass production through sublimation heat transfer machines (heating and pressing) for thermal transfer processing to transfer good patterns on the product surface, ink layer, and molded product surface to improve product quality.
