The process of silicone heat transfer screen printing usually includes the following steps:
1. Preparation stage
Material preparation: Prepare necessary materials such as silicone, transfer glue, hot melt glue, silicone release transfer film, color paste, etc. Make sure all materials are within the validity period and mix them in proportion.
Equipment debugging: Check the status of equipment such as heat transfer machines and presses to ensure that they can work properly. At the same time, adjust the parameters of the equipment, such as temperature, pressure and time, according to actual needs.
2. Printing stage
Silicone screen printing: After mixing the prepared silicone and color paste evenly, screen print them on the high-temperature release film through the screen. Print as many times as needed to achieve the desired thickness and color effect.
3. Transfer stage
Heat transfer: Place the printed pattern (pattern face down) on the treated silicone substrate and put it into the heat transfer machine or press. Heat and press according to the parameter settings of the equipment. Usually, the transfer time, temperature and pressure need to be strictly controlled to ensure the quality of the transfer effect.
Cooling and peeling: After the time alarm of the heat transfer equipment, lift the heating plate or take out the product and quickly peel off the pattern paper. Then let the product cool naturally for a period of time to ensure a strong bond between the silicone and the substrate.
4. Subsequent processing
Inspection and trimming: Check the quality of the transferred products to ensure that the pattern is complete, the color is uniform and there are no defects. If necessary, trimming or rework can be performed.
Packaging and storage: Pack and store the qualified products. Ensure that the packaging materials meet the requirements and can protect the products from damage or contamination. At the same time, the storage environment also needs to be kept dry, cool and well ventilated.
In summary, the process of silicone heat transfer screen printing includes multiple steps such as preparation stage, printing stage, transfer stage and subsequent processing. Each step requires strict control of parameters and conditions to ensure the quality and effect of the final product.
