There are various types of customized processing techniques for silicone products, and different types of silicone products require different production processes. Most products cannot avoid the silk screen printing process, which is not only used in the silicone industry. In daily life, many product patterns and logos need to be printed using silk screen printing. Due to its numerous advantages, silk screen printing can be recognized in many industries. Its printing process uses two-component liquid silicone and curing agent color paste to mix and produce the required silk screen colors, and finally completes the silk screen printing process through a silk screen machine. In the silicone product industry, its purpose is to achieve the engraving of product appearance patterns with fonts.
The screen printing process has many excellent characteristics compared to other processes. Firstly, it has good fluidity, strong adhesive viscosity and clear effect, high and low temperature printing stability, and good weather resistance and aging performance. The patterns printed by screen printing have a more three-dimensional and tactile feel, and the screen printing patterns also have excellent peel strength, wear resistance, and brightness; It also has waterproof, anti slip, breathable, high and low temperature resistance, and outstanding leveling properties.
What are the details that silicone product manufacturers need to pay attention to during the screen printing process? The quality of silk screen printing is closely related to the quality of the pattern. Therefore, in some processes such as silicone buttons and silicone gift cups, the ink applied to the product is also crucial for the silk screen printing process. High quality ink can improve the quality of the pattern. However, some products may experience color fading after long-term use, mainly due to the following reasons:
1. The quality of screen printing ink is relatively poor, which affects the surface of silicone products and leads to poor screen printing effect;
2. After silk screen printing, the baking temperature of silicone products is too low or the baking time is too short, which leads to poor wear resistance of the silicone product patterns produced by silk screen printing. After several uses, the patterns begin to become blurry;
3. The surface of silicone products is too dirty and not cleaned before screen printing, which hinders the adsorption between screen printing ink and silicone, causing characters to fall off with a slight force.
