Silicone jewelry has now become the mainstream of craft jewelry, and many types of decorations have become gifts, etc., all made of customized silicone materials. Most of the reasons are inseparable from its craftsmanship and appearance treatment, such as sun stripes, multi-color three-dimensional, oil spray textures, silk screen patterns, etc. Among silicone gifts, bracelet accessories are the main type, and silk screen patterns have become mainstream nowadays, but silk screen patterns also have their drawbacks. How to solve problems such as uneven ink and oil droplets in products?
Screen printing belongs to oil-based processes, and silicone rubber products cannot do without screen printing technology. In order to enhance aesthetics, ink is used for pattern printing, and the quality of ink is naturally crucial for the adjustment of transfer printing machines and the processing methods of products. Many friends may have been wearing silicone bracelets and other accessories for a period of time, but their words have fallen off. So what is the reason for this problem?
The main reasons for missing words in printed silicone wristbands are as follows:
1.Ink problem: The ink purchased by the silicone bracelet manufacturer or the ink prepared by oneself is not well prepared, and the diluent is very important. For example, when preparing, its matching degree may be more or less incorrect, which can cause incompatible reactions between ink and silicone gel, such as unclear screen printing, ink loss after a period of use, cracks in screen printing patterns, uneven ink, and so on!
2.Technical issues. The silk screen printing process of silicone jewelry is very important, such as how to place and position it, and how to dry the mesh. Especially during screen printing, is there any residue on the printed part of the product. Silicone rubber products that are too dirty can cause the adsorption of screen printing ink, so many silicone manufacturers usually clean the products first.
3.Baking issues are the main reason. Many products are baked at high temperatures after screen printing, but they still come off when touched. The oven problems of many products are closely related. Different products have different baking temperatures, so it is very important to properly control product issues! Secondly, if the speed of the oven tunnel is too fast, it may cause the air to dry out, so the ink cannot drop until the main screen pattern is completely cured.
4.After using it for a while, it fell off, but the initial state was still good. The reason is that in environmental use, ink aging, peel strength, wear resistance, and gloss effect cannot be achieved. Ink is the main issue, so printing with high-quality ink can maintain the quality of silicone jewelry.
