2. Pre-shrinkage:
Before printing, the cut Film is heated in the oven to minimize the chance of shrinkage.
3. IMD graphic printing:
According to the custom-made mobile phone shell design street patterns, text manufacturing into Film net, in the cut Film square block printing patterns and text.

5. IMD paste protective Film:
Avoid the printing of the Film surface during the positioning hole process, sometimes need to paste a single or double protective Film.
6. IMD punching positioning hole:
The positioning hole in the shearing process and the hot forming process must be punched accurately.
7. IMD thermal molding (high pressure or copper mold) :
After the printed film is heated, it is formed under preheating state by high pressure machine or copper mold.Forming Mold design is critical.
8. IMD shear peripheral shape:
Cut off the waste of the formed three-dimensional film.Precise shear mode is required.
9. IMD injection molding:
Place the film with the same three-dimensional shape on the front mold after molding to inject the finished IMD product
