With the rapid development of printing and packaging industry, hot stamping has become an indispensable new processing technology in the printing and packaging industry. Bronzing process consists of traditional bronzing and special bronzing

special hot stamping is different from traditional hot stamping

1 In the process of hot stamping, there is no need to make metal relief, which is low cost and fast. As long as there is a positive negative, hot stamping can be carried out

2. It is suitable for the production of small batch and multi variety personalized hot stamping products

3. The hot stamping temperature is low, 100 to 130 degrees

4. It is suitable for hot stamping of large areas and fine lines

5. Hot stamping substrates are not restricted, such as various plastic films, paper, leather, metal, glass, etc

6. Good adhesion to hot stamping substrate. After curing, the photosensitive film has the characteristics of high brightness, constant yellow and no scratch

specific hot stamping process

1. Brush the photosensitive ink with 200 ~ 300 mesh silk or spray the substrate to be hot stamped evenly with a spray gun. Liquid photosensitive ink is a kind of transparent varnish, which is specially used for all kinds of hot stamping for most of the use of high molecular polymers. It has excellent photosensitivity, high graphics resolution and a minimum line width of 0.05 mm

2. dry. Use electric wind to dry or use silk plate oven to dry, and pay attention to the temperature of about 40 degrees

3. Film exposure. The computer design and production results show that the bonding strength between unidirectional thermoplastic composites and injection molded thermoplastics is 84% better than that of substrate laminates. The following three common problems are required: hot stamping graphics and texts, output negatives for ultraviolet exposure. After UV exposure, the photosensitive film of the non pattern part becomes thermosetting, and the pattern part is still thermoplastic

4. Hot stamping. In the process of hot stamping, the adhesive layer of gold and silver hot stamping foil and the thermoplastic part of the photosensitive film are bonded together due to hot melting, and do not adhere to the thermosetting part, so as to realize the thermal transfer of the hot stamping film. Hot stamping equipment can be used for hot stamping with plastic sealing machine, electric iron and hot stamping machine. The temperature can be controlled between 100 and 130 degrees

5. Hot stamping finished products. After hot stamping, gently tear off the excess hot stamping film into a dazzling finished product
