1. Adopt imported actuator: lower noise and longer service life 2. Microcomputer control, safe and reliable operation 3.After stirring, it can produce impression material without bubbles, good elasticity, not easy to deformation, modulus more clearly; 4. Time setting range is between 1-24 seconds by the user, according to different impression material characteristics to choose; 5.According to user needs, there are three computer memory setting ( default setting is 8 seconds" scoop of powder",10seconds two scoop of powder,"12 seconds" three scoop of powder" ); 6.Internal temperature can be controlled, which make it possible that work continuously for a long time without affecting the impression material production;
