I use a hot melt glue gun to apply a layer of insulating material to the surface of the plug. It's essential to ensure that the hot melt glue gun has been fully preheated so that it can extrude a sufficient amount of glue smoothly. For low-power glue gun models, it's difficult to achieve continuous and stable extrusion. At the same time, please remember: the curing time of hot melt glue is about one minute. The mold is made of PET-G material, with a 0.4mm nozzle and a layer thickness of 0.1mm for

Operation steps:

1. Apply lubricant evenly on the surface of the mold
2. Preheat the glue gun for 6 minutes
3. Pour an appropriate amount of glue into the two halves of the mold from the side of the cable
4. Clamp the two halves of the mold together and fix them
5. Continue to inject the adhesive solution into the hole until the adhesive solution completely fills the inside of the plug and starts to overflow from the outside
6. Let it sit and cool for 5 minutes
7. Be careful to open the mold in half and scrape off the excess glue with a blade
