Requirements for thermal transfer processing technology

The following aspects need to be paid attention to in the technical requirements of thermal transfer printing:

1. The hot stamping temperature of the thermal transfer processing flower film is 120 degrees Celsius - 240 degrees Celsius. It can be applied to the coating surface of ABS, AS, PS, PVC, PMMA, PP, PE and other plastic products, metal, wood, etc.

2. The plate-making electroengraving plate of the printed flower film is mainly used for pictures and texts with rich transition colors and layers. It can reproduce the effects of characters, landscapes and high-grade pictures and texts. The printed pictures and texts are clear, accurate, and have strong adhesion. It is suitable for plastic products, cultural and educational supplies, daily chemical packaging, etc. with large quantities and high requirements. The hot stamping temperature of the thermal transfer printing film is 120 degrees Celsius - 240 degrees Celsius.

It can be applied to the coating surface of ABS, AS, PS, PVC, PMMA, PP, PE and other plastic products, metal, wood, etc.

3. Precautions for hot stamping processing of thermal transfer printing film:

Hot stamping is a special printing process. Its working principle is very simple. The graphics and text on the flower film are transferred to the product through heating and pressure. However, in the specific production practice, it is necessary to improve the quality of the product and improve the production. Efficiency, also need to pay attention to the following points:

1) Keep it clean:

① Keep the worktable, guide rollers, buttons and other parts of the machine clean and free from dirt such as oil stains;

② Keep the flower film clean and free from oil stains, fingerprints, dust, etc.;

③ To keep the rubber head clean, there should be no dirt or coke sticking on it;

④ The operator's hands should be kept clean, and there should be no sweat or oil stains on the flower film or the scalded product;

⑤ Keep the scalded objects clean and free from dust, oil, etc.;

2) Hot stamping pressure: The hot stamping pressure must be adjusted to the most appropriate, otherwise it will easily damage the rubber head and the object to be hot, and if it is too small, it will affect the hot stamping effect.

After adjusting to the best hot stamping pressure, the pressure adjustment should be locked to avoid changes in mass production.

3) Hot stamping time (speed): The hot stamping time (speed) should be determined according to the specific hot stamping material. Under the condition of ensuring the hot stamping effect, the faster the speed, the higher the production efficiency. However, some products are subject to certain special conditions. Only slow hot stamping must be used.

4) Hot stamping temperature: The hot stamping temperature varies according to the hot stamping equipment, hot stamping film and hot stamping material. Do not blindly pursue the higher or (lower the better) hot stamping temperature, and the effect after hot stamping should be Benchmark to determine the stamping temperature.
