The characteristics of mobile phone plastic hard case

That is, the mobile phone protective case manufactured by the plastic injection molding process, the main materials are: PC (polycarbonate) ABS acrylonitrile-butadiene-styrene copolymer The main features are:

The product can be made very thin, the appearance is very hard, and the surface of the product can also be printed with various patterns, such as cartoons, landscapes, and characters. The printing technology ranges from the earliest silk screen printing to the later transfer printing. The biggest disadvantage of this printing technology is that the appearance is easy to wear. At present, the most popular is the IMD/IML (in-mold transfer) technology, that is, the pattern is printed in the film, and then formed with the product shell. The product pattern produced in this way is inside the film, and it is not easy to grind the pattern. And the production is more convenient. The patterns include not only traditional cartoons, characters, landscapes, but also metal-like effects.

Products without patterns are usually made in various colors. There are generally two ways to make colors:

1. The color can be adjusted to the corresponding plastic materials during production, so that there is no need to spray color oil during molding;

2. After molding with ordinary plastic, spray color oil on the surface of the product.

In order to increase the hand feeling, some products also spray a layer of hand-feeling paint on the surface, that is, the traditionally said rubber oil, the hand feeling will become finer and have a small elasticity. Professional injection molding machine manufacturers with absolute status in domestic production and use, such as Shunde Yizumi, have many successful cases for reference.
