“…This was a compression mold with a cylindrical part cavity of 100 mm diameter and 5 mm thickness (Figure 3). The thermal regulation of the mold (Figure 2) included a heating and a cooling systems 20. Heating power was provided by two double spiral electrical resistors [(a) in Figure 2] associated with two electrical power suppliers of 1 200 W. The cooling system was based on two compressed air channels controlled by two solenoids and powered by an air compressor providing a controlled air pressure in the cooling circuit [(b) in Figure 2].…”

The thermal conductivity of a rubber compound is studied as a function of its state of curing. The device is presented and the calculations in order to obtain samples with controlled and homogeneous vulcanization rates are performed. The hot disk technique is used to measure the thermal conductivity of the rubber. This transient, plane‐source and non‐destructive method allows rapid and accurate measurement of the thermal conductivity based on the measurement of the electrical resistance of a plane sensor placed between two identical samples. The obtained results show that the thermal conductivity may vary significantly as a function of vulcanization rate. The effect of this variation on the prediction of the reaction progress is discussed.

“…The whole thermal behavior of the mold has been optimized in order to have 1D heat transfer along the axis of the mold. For a more detailed description, the reader can refer to our earlier works [11,12], where it is used with different central part modules.…”

“…Nevertheless, there are disadvantages because the FDM faces difficulties when modeling complex geometries [ 21 ]. The FEM enables the vulcanization optimization of rubber products under complex conditions and, hence, it is extensively used to solve heat transfer equations [ 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ]. With advanced vulcanization simulation, specific values of various reaction parameters and crosslinking structures can be determined at any time for any point in the vulcanization field, enabling effective vulcanization prediction.…”

The kinetic model, encompassing the curing and reversion phenomena of the NR/SBR rubber vulcanization process, was developed by means of the finite element method simultaneously with heat transfer equations, including heat generation due to curing reactions. The vulcanization simulation was conducted for three spheres of different diameters (1, 5 and 10 cm) and two rubber wheels, one of which was a commercial product of the rubber industry. The proposed advanced simulation model, based on products’ two-dimensional axisymmetry, includes cooling after vulcanization, during which the crosslinking reactions continue to take place as a result of the products’ heated interiors. As a criterion for removing the product from the mold, an average vulcanization degree of 0.9 was set, whereby, during cooling, the vulcanization degree increases, due to crosslinking reactions. Based on the minimal difference between the maximal and minimal vulcanization degrees, which did not exceed a value of 0.0142, the optimal process parameters for each product were determined, achieving homogeneity and obtaining high-quality rubber products, while simultaneously ensuring a more efficient vulcanization process and enhanced cost effectiveness for the rubber industry.
