To effectively utilize a hot press, it is essential to have a thorough understanding of its key components and cleaning methods. Let us now take a closer look at the hot press.

Key components of the hot press:

1. Frame: Primarily serves to support the hot-pressing platens and hydraulic cylinders; it also bears the total pressure exerted by the machine during operation.

2. Hydraulic cylinder: Primarily used to facilitate reciprocating linear motion.

3. Hot-pressing platen: A critical component responsible for transferring pressure and heat. Furthermore, the platen's mechanical strength, rigidity, and heat transfer capabilities directly influence product quality and equipment efficiency.

Before cleaning, drain the existing heat transfer oil from the system and verify that the circulation piping is unobstructed to ensure proper flow. System valves should be cycled periodically to ensure all components are thoroughly cleaned; it is recommended to switch the valves once per hour. The standard cleaning duration is four hours, though this should be extended if there is a thick layer of oil residue within the system. Open specific sections of the circulation piping to inspect the cleaning progress; if oil contamination persists, extend the cleaning time until all components are clean before proceeding to the next step.

Drain the cleaning agent and oil mixture from the system into a clean container; if possible, use an air compressor to purge any remaining liquid from the jackets. Do not discard the cleaning agent after use; although it may turn black, it remains reusable. Since the cleaning agent effectively dissolves oil coke, an oil layer will form on the surface of the fluid, while sludge settles at the bottom. Simply pump off the surface oil layer, and the remaining cleaning fluid can be reused for future equipment cleaning.
