Introduction to the surface technology of PVC products

Now on the market, there are many custom PVC products including PVC keychain, custom PVC patches, PVC protective case, custom PVC Coaster, vinyl anime figure and more. The custom PVC products that we see most are printed with characters on the buttons and have light transmission effects, and the realization of light transmission effects. Now the PVC product factory will tell you how to realize the printing of PVC products with characters in three ways. That is, the character printing process, laser engraving process, and ink drop process are realized on the surface.

l  Silk silicone Screen Printing

Make silicone Screen Printing related to LOGO, and add permeable PVC ink to the characters on the screens. Note: Except for ink and non-permeable ink, they are all sealed with glue. In the production process, it is necessary to pay attention that the PVC ink is placed on the screen, and the characters on the screen are aligned with the positions of the characters to be printed on the PVC products.

In addition, when the silk silicone Screen Printing scraper with PVC ink is used to scrape PVC products, the silkscreen position is required. The PVC ink penetrates into the surface of the PVC product through the space left on the screen, forming a font on the surface of the PVC product. Some companies will silk silicone Screen Printing some company brand logos or slogans on custom PVC patches for corporate promotion..

The printing process is easy to operate and low in cost, but the character friction life is relatively low. For PVC products that require too high character friction life, a layer of PU needs to be sprayed on the surface to improve its anti-friction life.

l  Laser engraving

Let’s take an example of transparent or semi-transparent PVC background color buttons. After spraying the ink of the required color on the surface of the PVC button, laser processing is performed on the surface of the PVC button with a laser engraving machine to form the required characters and achieve a light transmission effect. Engraving can make PVC button products easy to use in low light conditions, just install the led light at the bottom of the button as the light source

l  Tri-color drop ink

Make glyphs in the PVC mold--make the required glyph grooves on the surface of the key after the PVC product is formed. Then drop the PVC ink in the groove, and dry the ink in the groove through a tunnel oven, so that it is firmly absorbed in the character groove of the PVC product, thereby forming the character dripping ink process, which can make the characters on the surface of the PVC product basically will not wear out.

In order to achieve the unique effects of PVC products, the above are the three most commonly used methods. Each method has its own advantages and disadvantages, so the choice of which method should be based on the actual needs of the product. Our suggestion is that customers choose the best way based on different products used by different products.
