The process of making a device for melting plastic bags using a glue gun
To use a glue gun as a plastic extruder, you must first process the bags into sticks. This will require a special form. To make it, a thin tube is selected, the internal diameter of which corresponds to the cross-section of the glue sticks of the existing gun. At least one edge must be equipped with an external thread. A plug or cap nut is screwed onto it.
Bags marked HDPE are stuffed into the mold and sealed with a bolt.Then it needs to be heated to 120°-135°C. This can be done in the oven. Next, a bolt is inserted into the mold with hot plastic, and they are clamped in a clamp or vice.
After cooling, the plug is removed and the plastic rod is knocked out of the tube. Now it can be installed in a glue gun.
He will heat up the plastic and squeeze it out through the spout.
