Face mold is unpopular in mechanical processing, and it is generally displayed to test the degree of finish of CNC machine processing, corner matching performance, and attracting popularity.
Say the face mold, the expert understands, test the processing performance of the machine center.
But in the eyes of the layman, you may not know what it is and what it is used for. Let me mention an ancient technique. I think you've all seen Transfiguration.
In some novels or movies often about the description of transappearance, often turn around to become another person's appearance, here is not completely true, a person to become another person's appearance, this is possible, but in a short period of time is impossible, and also needs to be the full cooperation of the person. Therefore, most of the ancient transfigural art is exaggerated, and at the level of technology at that time, it is impossible to make a simulated "transfigural mask".
But now there is a CNC machining center to do this is much easier, such as scanning a star's face, using the machining center directly to mill out the mold, and then, a white milk liquid called "silicone glue" and the foundation and uniform, applied to the inside of the model. After drying, it is picked up with tweezers and made into a mask that is finally affixed to the face, which is the prototype of the so-called "human skin mask", and then modified and made up, it can achieve a magical effect. And this can be mass-produced. Can you imagine a bunch of celebrities in front of us?
