　　Once the stretching is done, we move on to heat setting. Heat setting stabilizes the stretched geogrid and locks in the molecular orientation. We heat the geogrid to a specific temperature for a set period. This temperature and time are determined by the type of PET resin and the stretching ratio.

　　We have temperature - controlled ovens for heat setting. Inside the ovens, we use fans to ensure uniform heat distribution across the geogrid. After heat setting, the geogrid is cooled down gradually. This slow cooling process helps prevent internal stresses from building up in the geogrid, which could lead to warping or cracking over time.
