Bronzing and thermal transfer process
Round flat hot stamping method is actually the process principle of plane heat transfer machine. Plane heat transfer machine is mainly aimed at plane substrates and large curved surface transfer. Can be carried out round flat transfer products mainly in the following forms: the entire surface needs to be transferred to the product. Panel of household appliances, one side of cosmetic box, upper surface of plastic gift box or wooden jewelry box, toy puzzle board, plastic decorative mural, table display stand, fan surface, PVC plastic board, snowboard, plastic propaganda picture. By designing a floating device on the workbench, the round flat hot stamping machine can transfer special products with complex shapes. Representatives of this type of heat transfer machine are KC-H-150M and KC-H-300M. We usually put the embossing device for the transfer machine of the rubber roller as a heat transfer machine.
Hot stamping principle and process conditions
The main material of hot stamping is anodized aluminum, also called hot stamping foil. It consists essentially of two thin layers, a polyester film substrate and a transfer layer. During hot stamping, the transfer layer is imprinted on all or part of the surface of the printing object by virtue of heat and pressure. When hot stamping is completed, the polyester film edge is torn off together with the part that has not been transferred.
Features of thermal transfer equipment
Thermal transfer processing is a special way of printing, and thermal transfer equipment is the use of thermal transfer processing to transfer the machine. Thermal transfer processing has transfer film printing and transfer processing.
Traditional thermal transfer technology
Thermal transfer printing is a printing process that has been rising in China for less than 20 years. It was introduced into China from abroad in the 1990 s. Through the continuous efforts of industry peers to explore, research, development has become a mature and updated faster printing process. Because the process has great advantages in controlling production costs and improving product appearance, it is highly respected in the printing industry and continues to develop.
What is the difference between thermal transfer printing technology and digital printing technology
Thermal transfer printing technology is a new method of printing patterns on various materials, especially suitable for making a small number of personalized and customized products, as well as printing patterns containing full-color images or photos. The principle is that the digital pattern is printed on the special transfer paper with special transfer ink through the printer, and then the special transfer machine is used to transfer the pattern to the surface of the commodity under high temperature and high pressure to complete the printing of the commodity.
Thermal transfer technology film production process
There are many kinds of carriers for heat transfer film, and PET is widely used. It has the characteristics of good dimensional stability, uniform tension, good heat resistance and good release. In particular, it has obvious advantages in the reproduction of color gradation originals. The specifications of the film, such as width, thickness, size and grade, are selected according to the manufacturer's requirements. At the same time, it is necessary to check the flatness of the film and whether the barrel material has "protruding ribs", "flounces" and other conditions that do not meet the quality requirements.
Daily maintenance of hot stamping equipment
The hot stamping machine can hot all kinds of hot stamping on cotton, hemp, chemical fiber and other fabrics by thermal transfer printing. It can also be heat-treated by screen printing, mucilage, foaming and other processes. It can also bake color labels, portrait photos, landscape patterns and the like on porcelain plates and metal plates. It is especially suitable for making medals, commemorative cards, cultural shirts and the like. It is economical, practical and has exquisite patterns. It is replacing traditional embroidery and screen printing, but the cost and effect are much lower and better than general embroidery and multi-color screen printing.
