Question: In the molding of thermosetting plastics, should the molding pressure be decreased or increased accordingly when raising the mold temperature to benefit the molding process? Why? Answer: In the molding of thermosetting plastics, increasing the mold temperature generally requires an increase in molding pressure as well, which is beneficial for the molding process. Within a certain range, increasing the mold temperature can enhance the fluidity of the plastic, allowing for a reduction in molding pressure. However, an increased mold temperature also accelerates the cross-linking reaction of the plastic, which in turn leads to a rapid increase in the viscosity of the molten material, requiring higher molding pressure. Taking all the above factors into account, increasing the mold temperature generally requires a corresponding increase in molding pressure.

To increase the mold temperature, the molding pressure should generally be increased accordingly, which is beneficial for the molding process. This is mainly because an increase in mold temperature accelerates the cross-linking reaction of the plastic, which in turn causes the viscosity of the molten material to rise rapidly, thus requiring a higher molding pressure.

Answer: In the molding of thermosetting plastics, increasing the mold temperature generally requires an increase in molding pressure as well, which is beneficial for the molding process.
The mold pressure should also be increased simultaneously. When the processing temperature of thermoplastic materials increases, the increased mobility of molecules leads to a higher coefficient of expansion, an increase in volume, and rising internal pressure, making it easier for these materials to leak out through the gaps between the mold parts. At the same time, as the temperature of the material increases, the recovery rate of the molded products after demolding also rises, which affects the yield of these products; increasing the molding pressure can reduce the recovery rate after molding. Only by increasing the molding pressure and prolonging the holding time can the density of the product be increased, thereby reducing the recovery rate.
