Using direction:
1. The Method of Moulding: Compression molding.
2. Set the dry mould on the the pressure machine, open the machine and make the mould heating, the temperature should be 160C.
3. Beforehand, you should calculate the proper quantity of the materials in the mould.
4. Preheating the materials for 3-10 min as the temperature of 80-100C.
5. Put the materials in the mould, and close the mould.
6. Press the mould with the pressure of 45±5MPa, and holding them for 1-3 min (according to the thickness). If it is necessary, you can have to deflate 1-3 times.
7. Open the mould, and the materials will be formed.
Notes:
The above parameters for reference only, since the user produce workpieces of different shapes, different production conditions to determine the molding process, through the experiments to products qualified shall prevail.
