1. Natural aging:


Natural aging means that if the cast iron platform is stored at room temperature or under natural conditions for a long time, the residual stress is relaxed and the dimensional accuracy is stabilized, which is called natural aging treatment.


The advantages of natural aging are that the cast iron platform has good dimensional stability, the method is simple and easy to implement, and it is environmentally friendly.

The disadvantage is that the production cycle is long, the space is occupied, it is difficult to manage, and the defects in the inspection platform cast iron platform blank cannot be found in time, which has been gradually eliminated.


2. Artificial aging treatment:


Artificial aging is an aging treatment process that heats the cast iron platform to a higher temperature and performs aging treatment in a short period of time, which is called artificial thermal aging treatment.


The advantages of thermal aging of cast iron platform blanks are short cycle, good dimensional stability of cast iron platform, and easy management.

The disadvantages are large one-time investment, high energy consumption, high cost, difficult temperature control, high labor intensity and serious environmental pollution. So it is gradually replaced by vibration aging.


3. Vibration aging:


A certain frequency of vibration is applied to the cast iron platform to release the internal stress, so as to achieve the purpose of aging.
