WHAT IS A "FACTORY TUNING"

Hi, people. Pay some attention, please.
This is an actual rubber compositon (1) comprising no oil ingredients to prepare the end product. Thus, in order to improve the sponge quality, a final treatment on the sponge may be applied with a hot oil bath. As an example, Yinhe Big Dipper sponge is being steeped into hot oils, the process known as a "factory tuning".
