You may be familiar with hot glue guns from your high school home-economics class. You may remember weird, cylindrical, solid-but-flexible, sticks of translucent glue that you placed into a small hot glue gun. The gun would heat the glue, and you could use the hot glue to adhere pieces of fabric together (or to make other craft projects).
Hot glue also has the name of hot melt adhesives, which is the term typically used in industrial settings (or just “hot melt” for short). Indeed, what you may not know is that hot glue has many more uses than craft projects. Many industries use hot melt as part of the manufacturing and assembly process.
For example, one common consideration in the world of electronics adhesives is choosing an adhesive that can stand up to vibration. When affixing extremely delicate wiring to a motherboard or in other fragile circuit board situations, we would recommend using a hot glue adhesive to hold the component tightly in place without jeopardizing the overall quality or health of the electronics themselves — a process also known as potting or overmolding.
After using a hot melt adhesive to hold the electronic component in place, many electronics manufacturers opt to follow up with a neutral cure silicon rubber to create a long-term bond. While the hot melt glue creates a great short-term solution for holding the component in place and resisting vibration for month or years, silicon rubber provides a bond intended to last decades when applied correctly.
Unlike other industries where manually applying adhesives with glue bottles or glue sticks may be an option, the electronics industry requires more automated solutions for more consistent application. Commonly used industrial glue machines for electronics, including hot glue guns, can help make quick work of the process. Additionally, professional-quality glue guns offer a precise application with fewer drips and strings that can easily damage sensitive electronic equipment.
Choosing the right hot melt glue
Glue guns are an effective and convenient tool for fastening various materials. Before selecting a glue gun, you need to know what type of hot melt glue you will need for your project. Rapid glue sticks are grouped according to the three most common applications.

Of course, when it comes time to jump your battery, it's very important to handle the cables properly. Always keep the red and black clamps from touching, and be sure the cables stay apart when you're getting set up — especially once you have the clamps connected to a live battery. If the clamps touch when they're "hot," it could short out one or both cars and will definitely create some sparks.
Since using jumper cables incorrectly can be dangerous, follow every step precisely. Most jumper cables have an instruction card or label so you can make sure you're connecting them the right way.

Little dents in your car are frustrating. Sometimes, a ding in a car park can cause noticeable damage to the bodywork. Many car owners are turning to car dent pullers to try and repair the damage themselves.
Dent removal kits pull dents from the outside of the car, unlike Paintless Dent Removal techniques, which push dents out from the inside. Car dent pullers are widely available and cheap to buy, but do they work?
Before you attempt a DIY dent removal, read our advice on the types of car dent pullers available and when to choose a professional dent repair service.
Car dent pullers lift dents out of car bodywork and straighten the metal out. There are two main types of pullers: suction and glue kits.
