Hot Melt is a process of adding an adhesive to the inside of a golf club head through a weight hole, hot melt portal, or drilled entry. Nearly any driver, wood, or hybrid head that is mostly hollow can have this service done if requested. Older heads such as true wooden heads are not applicable. The Hot Melt process is done to most if not all tour clubs.
There are two main reasons to consider Hot Melt:
- To create a bias or add weight.
- For feel and sound dampening.
