Thermal transfer film has its own unique properties, in order to obtain the ideal hot stamping effect, we must strictly master the temperature, pressure and speed. It has strict three major process parameters:

1. The determination of temperature: when the temperature is too low, hot stamping will not be achieved or the hot stamping will not be firm, and the blot will be bloomed; too high temperature will oxidize the surface of the color layer, make the product lose luster, and the color will become dark, serious Will bubble. To determine the stamping temperature, the following factors should be considered: pressure, speed, area, room temperature, etc. The hot stamping temperature generally ranges from 140°C to 180°C. Once the temperature is determined, it should be kept constant and the temperature difference should fluctuate within ±2°C.

2. Determination of pressure: The stamping pressure is generally 4-6 kg/cm2. If the pressure is too small, the hot stamping film cannot adhere to the substrate and the fastness is reduced; if the pressure is too large, the compression deformation of the substrate will increase, resulting in deformation of the pattern and thinning of the printed layer. If you stamp complex and uneven products, you should pay more attention to the uniformity of each pressure point, and the pressure angle between the stamping wheel and the substrate is higher. Otherwise, it is easy to appear partially and partially unstable.

3. Determination of speed: It should be determined according to the area of hot stamping, and the power of heating temperature should be considered at the same time. Generally, the speed is determined first, then the pressure is determined, and finally the temperature is determined.
