The hot melt glue gun is a ubiquitous hardware tool and has a perfect glue dispensing effect. A wide variety of nozzles are available to meet the requirements of different scenarios, making it very versatile. Today we will give you few common knowledge. The working principle of a hot melt glue gun The hot melt glue gun will generate heat inside the gun body. When the temperature reaches the melting point of the glue stick, the hot melt glue will melt into a fluid because the hot melt glue gun will also be connected to a gas line, so there is air pressure. When the trigger is pulled, the internal air pressure will make the fluid state of the hot melt glue from the gun nozzle spray. Air pressure can be set. There are differences in glue, such as point, line, spiral, spray, etc. These need to be selected according to the process. What is the difference between the different powers of the hot melt glue guns? Put, within a certain period, the melting efficiency differs from one power to another. Generally, the higher the power, the faster the melting speed. The higher the wattage, the faster the melting speed. The higher the wattage, the faster the melting speed, the more suitable for large glue guns to melt thicker glue sticks. Tips and tricks for sticking things with hot melt glue When gluing things together, make sure that the two glued objects are clean and free from moisture, dust, and oil. Otherwise, the adhesion of the hot melt glue will be affected. How do I use a glue stick if I don't have a hot melt glue gun? You can use a lighter to melt the glue, and when it is about to drip, apply a layer of glue to the part to be glued, then stick the object to be glued and let it cool down a bit. For long-term use, we recommend using a candle to burn the hot melt glue stick. The hot melt glue gun is used for heating, so you can use another object to heat the glue instead of the gun, and the hot melt glue stick can be used again. How do I store my hot melt glue sticks? It is straightforward to store unused glue sticks in a dry room at room temperature but not place them in a hot environment or direct sunlight. Most hot melt glue has a shelf life of about two years, after which the stickiness will slowly diminish, some of the glue will yellow slightly after an extended period, but the stickiness is the same so that you can use it without worry. If the glue stick is still in the gun and not finished, it can be left in the gun and used after the next power preheating, do not pull out the glue stick in the glue inlet as much as possible. Otherwise, it will easily cause backward glue phenomenon or damage the gun body.
