  • Publication number: 20250178250
    Abstract: An apparatus for manufacturing a shoe material with a real-time temperature measuring system and a method for manufacturing a shoe material are provided and include a real-time temperature measuring system used in hot-press molding and cooling shaping processes and configured to measure a real-time temperature of a foamed shoe material in a mold while a device performs a temperature controlling process on the mold. The real-time temperature is compared with a temperature threshold stored in a central controller. When the real-time temperature is greater than or is less than the temperature threshold, the central controller sends a control signal to stop the temperature controlling process on the mold by the device. Therefore, the manufacturing time of the shoe material in the hot-press molding and cooling shaping processes could be shortened, the production efficiency could be improved, and the energy consumption of the device could be reduced.
