, making convenient than manual.
2. Use the molding plate to move up and down vertically and down with the knife block. The impor of polymer materials to make full use of the principle of balancing knife block stress reducing friction, solve the other knife block by means of a knife pushing other side knife movement is easy to wear, easy problem of weather changes and thermal expansion and contraction can not be normal production. The production is stable and the service life of the shaped cutte
