The heat exchanger seal ring vulcanizing machine is a professional hydraulic vulcanizing equipment specially developed for mass production and precision molding of various rubber sealing rings for heat exchangers. It is widely applicable to vulcanization molding of EPDM, silicone rubber, nitrile rubber and other rubber materials, perfectly matching the production demands of sealing accessories for industrial heat exchangers, HVAC heat exchange equipment and pipeline heat exchange systems. Adopting advanced PLC automatic control system, the machine realizes precise intelligent control of vulcanization temperature, pressing pressure, holding time and mold opening/closing action. The high-precision hydraulic pressure system provides stable and uniform clamping force, which effectively avoids bubbles, deformation and uneven density of finished seal rings, ensuring high dimensional accuracy, tight consistency and excellent sealing performance of heat exchanger rubber seals. Equipped with an optional vacuum system, it can thoroughly exhaust air from the mold cavity, greatly improving the compactness and surface finish of finished products.
