The polymer material is placed in the forming groove and heated by the annular heat conducting plate 103. After heating, the tablet is formed in cooperation with the contact pressing plate 5. A heating component 6 is installed at the heating chamber 102. The heating component 6 can heat the polymer material and dissipate heat quickly. When in use, the annular heat conducting plate 103 is heated by the electric heating layer 601.
