Before 3D printing revolutionizing global manufacturing, below are a few methods of printing we use frequently in making phone cases in China.
#1. UV Printing
UV printing, abbreviated from ultraviolet printing, uses UV inks rather than traditional inks, saving the trouble of drying and coating.
UV printing is a popular method we use a lot in manufacturing mobile phone covers in China. Before printing, first, blank phone cases should be prepared along with the design.
Then comes to typesetting, adjusting printing speed, direction, etc.
#2. Transfer Printing
Another popular way used in printing phone covers in China is transfer printing. In a simple way, a small transfer printing machine is needed, however, with the help of a mold.
As you can see from the picture below, transfer printing is applied to the shape of eyelashes, eyes and mouth of these mobile phone covers.
Since there are two colors in the design above, two molds, black and white inks are needed.
Sublimation is not only greatly used in clothes manufacturing in China, but also very prevalent in making cell phone covers, with similar uses.
Now with industrial 3D printing taking the mainstream, offering flexibility in prototyping, rapid tooling and low inventories, traditional ways of printing are dwarfed by their inflexibilities. Some big companies that can afford the exorbitant price tags of 3D printing machines in China have already set foot into this revolutional printing at its tippping point. As the cost of 3d printing equipment and material decrease, a revolutional shift would be under way.
