（3Product cooling is insufficient due to the molding cycle being a matter of money; even a reduction of a few seconds can yield a significant benefit. Thus, shortening the cooling time leads to products not being fully cooled, resulting in hard tops.

The solution is to find the balance point of interest; it's about whether to increase cooling time or add mechanisms—it requires a choice. I suggest thoroughly designing the mechanisms and cooling water paths, as shortening the molding cycle is the right approach.
