Do you know the processing methods of metal heat transfer?

1. The electro-engraving plate of printing flower film is mainly used for images and texts with transitional colors and rich layers. It can reproduce the effects of characters, landscapes and high-end images and texts. The printing images and texts are clear, accurate, and have strong adhesion. In large quantities, high-demand plastic products, cultural and educational supplies, daily chemical packaging, etc.

2. The hot stamping temperature of thermal transfer flower film is between 120 degrees Celsius and 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. Matters needing attention in the hot stamping process of thermal transfer flower film: Hot stamping is a special printing process, and its working principle is very simple. The graphics and text on the flower film are transferred to the product by heating and pressing. However, in the specific In production practice, to improve product quality and production efficiency, the following points should be noted:

⒈Keep clean:

A. Keep the scalded object clean and free of dust, oil, etc.;
B. Keep the rubber head clean, and there should be no dirt or burnt sticks on it;
C. Keep the flower film clean and not contaminated with oil, fingerprints, dust, etc.;
D. The operator’s hands must be kept clean, and no sweat or oil stains on the flower film or hot products;
E. Keep the workbench, guide rollers, buttons and other parts of the machine clean and free from oil and other dirt.

⒉Hot stamping temperature: The hot stamping temperature is different depending on the hot stamping equipment, hot stamping film, and hot stamping objects. Do not blindly pursue the higher or (the lower, the better) the hot stamping temperature. The hot stamping effect should be the benchmark To determine the hot stamping temperature.

⒊Hot stamping pressure: The stamping pressure must be adjusted to the most appropriate, otherwise it will be too large and it will easily damage the plastic head and the hot object, and too small 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.

⒋Hot stamping time (speed): The stamping time (speed) should be determined according to the specific hot stamping material. The faster the speed, the higher the production efficiency under the condition of ensuring the hot stamping effect, but some products are limited due to some special conditions Slow hot stamping must be used.
