What are the environmental and temperature requirements for thermal transfer processing
Different materials require different transfer temperature. In terms of plastic, the transfer temperature of hard rubber (ABS, benzene, acrylic, etc.) is about 20℃ lower than that of soft rubber (PP, PE, etc.) . (The thermometer detects silicon and rollers, and the surface of the rubber sheet is between 90°C and 120°C), while the temperature required for PVC is lower (between 60°C and 80°C). Due to the heat-resistant film between the heat source and the substrate during the thermal transfer process, and the contact time is not long (the rubber roller transfer is about 1cm/0.5-1 second, and the rubber plate is directly pressed for about 1-4 seconds/time), Basically, it will not cause deformation of the substrate, but if the substrate is a soft flat plate of less than 0.5mm, there will be a small amount of deformation.
Thermal transfer processing first requires a dust-free or less dusty environment with the production site to avoid dust spots falling on the substrate or transfer film surface, which will make the pattern flawed; the surface of the substrate must be free of oil stains and moisture , Dust, workers should wear cotton gloves to take the substrate to keep it clean and clean. The air source of the transfer material should be kept dry. The water filter should be drained every day to ensure a smooth air path and normal air cylinder movement. http://www.dgqiaoer.com/
