The unpredictable behavior of the heating element in a Chinese glue gun has become the talk of the town. The service life, according to information from Internet users, varies from a few seconds after switching on to five years of proper operation. About the power of the heating element, we came across statements ranging from “virtually does not heat at all” to “heats quite satisfactorily.” This was the reason for the curiosity that arose, which prompted me to buy an inexpensive Chinese one to begin with. glue gun on the subject “unscrew - look”. That is, thoroughly familiarize yourself with the design of the device, and that’s all. I didn’t take any glue sticks; I probably won’t need them.

And now the melting chamber with a heating element installed on it appeared to the eye. Looks like a small jet turbine.
The clamp and thrust pad have been removed. Here I am a heating element. I note that at the installation site it lay flat, in the center and was in direct contact with the body of the melting chamber with only one of its planes.
I unwrap the rather careless packaging - an insulator. Inside there is simply a miniature ceramic heating element and two contacts for supplying 220 volts to it.
I took a closer look at the heater and rang the two sides with a multimeter. They call, but not everywhere. The darkening visible in the photo at the bottom is present on all sides and completely covers the adjacent end side. It doesn't ring. This is a ceramic coating on top of the heating element. Designed for direct contact with the body of the heating chamber and transfer of heat generated by the heater, without placing a dielectric spacer between them. This spraying is the dielectric gasket. It became clear that the heater was installed incorrectly by the manufacturer. He was lying on his side, and was also wrapped three times in insulating material. According to the existing dimensions of the heaters, 4 of them will fit on the installation site.
Guided by common sense (as far as God has given), I began to correct the manufacturer’s “jambs”. The dimensions of the contacts were brought into line with the dimensions of the ceramic heater. Exactly in length, and 1 mm less in height.
I made a millimeter-long bend at a right angle to prevent the contact from sliding down onto the body of the heating chamber.
This is how the contacts assembled with the heater began to look (top view).
The assembly resistance (located inside the clothespin) turned out to be 6 kilo-ohms. It immediately became clear that the 20W declared by the manufacturer would not be even close to being confirmed.
Exactly according to the dimensions of the ceramic heater, I cut out two copper plates 2 mm thick. It is necessary to somehow fill the void at the installation site and take heat from the sides of the heater.
The cut was made to allow the sides to be compressed. This will add reliability in holding the heater in place and is intended to improve heat transfer.
Sectional installation diagram. In the figure there are gaps between the individual components, but in a real assembly there should not be any.
Assembly completed. The heater without a gasket stands on a designated plane (end) covered with dielectric coating, with current-carrying contacts on the sides, then four layers of mica on three sides (taken from an old burnt soldering iron), and copper plates on the sides. The seal is the insulator on the right made of asbestos. I had a piece on hand and it seemed that it would be more reliable.
Here you can see that the sides are already pressed against the copper plates and hold the entire assembly, the ceramic heater is directly in contact with the wall of the heating chamber, and the electric. contacts are far from her.
The last thing to put in place is the clamp. The junction of the wires with the contacts must be insulated with ceramic insulators or something that fully replaces them.
After assembly, the first thing I did was measure the current consumption. When turned on, within a few seconds, there is a gradual current jump of 80 - 120 - 210 mA, then a sharp jump down - 20 mA. Mains voltage 225 - 230 volts x 0.02 A = maximum 4.6 W. And on the front panel of the gun, in plain sight, there is a nameplate indicating a power of 20 W. The glue gun will actually have the stated power if you install 4 heating elements. However, let’s not dream, but rather look at the video of the heating dynamics of a correctly assembled and installed (in my opinion) heating element.

The gluing temperature indicated by the manufacturer is 120 degrees, it was achieved in 2 minutes. Yes, you also need to heat up the glue stick, but I think the remaining 3 minutes (the control heating time before starting work is 5 minutes) is enough for this. Especially for "" - Babay iz Barnaula.
To create crafts and interior decorations, many different types are used. different materials and technician. Sometimes completely unexpected materials are used for this purpose, for example, hot glue. Photos of crafts made from hot glue arouse genuine interest and a desire to try to create something similar with your own hands.
What is hot glue?
Hot glue has another name - thermoplastic glue. The material itself consists of polymers that, when heated, acquire adhesive properties. Typically, hot glue is used to seal joints and glue products together.
Hot melt adhesive is sold in most construction stores. It is produced in the form of solid glue sticks, which differ in color, size and composition.
There is also glue different colors. To effectively and accurately melt and dispense glue, there are special glue guns into which rods are inserted.
Operating technique
The instructions on how to make a craft from glue are very simple - buy a glue gun, suitable rods for it and use your imagination.
The main thing when working with the material is to be extremely careful and attentive, because the molten glue heats up to a temperature of 200˚ C.
What kind of crafts can be made from hot glue at home? Hot-melt adhesive can be used to decorate vases, photo frames and other interior elements or to create independent decorations.
Candlesticks
The best place to start working with hot glue is: simple tasks, for example, from decorating a candlestick. You can create an imitation of wax drips on its surface or create a unique pattern. For this purpose, it is better to use colored glue or sprinkle it with colored glitter or glue beads on it.
For decoration, you need to choose wide, thick-walled candlesticks. This choice is due to the fact that the effect of the burning temperature of a candle can have a bad effect on the glue - the design may simply blur.
Before applying hot glue, it is necessary to thoroughly degrease the surface of the candlestick for better adhesion.
You can get beautiful ideas for crafts made from hot glue from the Internet or create your own original pattern.
Vase
You can use hot glue to create a handmade vase for sweets. Step-by-step production with a description for beginners will help you easily create such a craft.
In order to make a vase for sweets yourself, stock up on hot glue, a glass bowl that will serve as a stencil and rich cream. If you want your vase to be colored, use a glue stick with the desired color or buy spray paint of the desired shade.
Apply cream to the outer surface of the bowl - it will prevent the glue from attaching to the glass when applied. Warm up your glue gun and begin applying glue to the bottom of the bowl. Try to distribute the glue evenly - this will help form a smooth, stable bottom of your vase.
After applying the glue, you must wait until it is completely polymerized. You can begin to separate the glue from the bowl only after it has completely hardened, otherwise the craft may be irreparably damaged. After removing the hot glue basket, you can spray paint it.
rolling pin
For those who love working with polymer or ceramic clay, the idea of making rolling pins with patterns will be very useful. To do this, you need to take a new, clean rolling pin. the right size, degrease well and draw the required pattern on it with a pencil or marker.
Then use a glue gun to apply glue to the pattern lines and wait until it dries completely. You can also treat the rolling pin with cream or oil before applying glue - this will allow you to remove the glue after using the required pattern and apply a new one to it.
New Year decoration
For your child, you can conduct a master class on crafts using hot glue. Make a large drawing of a snowflake; you can ask the child to make a stencil. Then use carbon paper to transfer the design onto parchment paper for baking.
Apply hot glue along the contour of the drawn snowflake to make a three-dimensional copy of it. Carefully monitor your child's actions at this stage - he may get burns from the hot polymer.
Wait until the polymer has completely hardened and separate it from the paper. After the snowflakes have dried, they can be decorated with ordinary nail polish or spray painted.

Builders, as well as home craftsmen, who are often involved in renovating their apartments or fixing things, have appreciated the heat gun, which makes it possible to glue together with extraordinary ease. various surfaces. It is used by florists, designers and needlewomen, for whom a hot glue gun helps in making souvenirs, doing scrapbooking or creating designer dolls. It is handicraft lovers who often ask the question: how to choose a glue gun for needlework.
Types of heat guns
Glue guns are divided into several categories, namely:
- Professional;
- Household.
Professional ones are quite massive, they are used for long-term work, which is provided by a rod with a large diameter, which is necessary when carrying out construction work.
Household - can fit in the palm of your hand, are lightweight and convenient for gluing various small items and performing simple work, when decorating crafts or interior items.
- mechanical, that is, the glue is supplied by simply pressing the trigger;
- automatic when the adhesive is supplied using an electromagnetic starter.
Undoubtedly a tool for professional builders They are more reliable in operation, but their cost mainly depends on the modification, versatility and brand of the manufacturer.
Design
The body of the glue gun, to which the power cord is connected, contains elements that allow the tool to properly perform its functions:
- nozzle;
- hammer or trigger;
- cylinder for installing the glue stick;
- legs.
The great advantage of the model is the presence of a kind of recess on the body, through which you can determine the presence of remaining adhesive composition, the integrity of the rod and its timely replacement.
The body, made of plastic, has special legs built into it that allow the tool to be in a non-working state with its nose down, since in a different position it can overheat, which leads to malfunctions and failure of the gun.
The presence of a button that can turn off the power also has a positive effect on the operation of the tool, since it saves adhesive, which can leak between uses.
The hot glue gun, equipped with tips of various configurations, belongs to more complex modifications of products. Typically, such nozzles make it possible to change the diameter of the hole through which the glue enters the work surface and thereby regulate the amount of adhesive. Replaceable nozzles with long, small-diameter elements are used for gluing product fragments into hard to reach places. In this case, decorating with a glue gun requires great care and skill from the needlewoman.
Replacement parts are made of metal, and manufacturers who value their reputation provide them with a rubber or silicone protector, which significantly reduces the risk of burns.
In order to understand the principle of operation of this tool, you need to have an idea of how the glue gun works inside. This will help you determine some of the parameters and characteristics of the device.
So, a heat gun is a tool, inside which a polyurethane adhesive substance is heated to liquid state. The device is charged from the back with rods, the diameter of which varies from 7 to 11 millimeters.
The rod, passing a special bushing, enters a rubber tube, after which the spare tire is driven into a chamber where, under the influence of the temperature created by the heating device, the polyurethane composition is melted. This process takes about five minutes. Then, the action of the trigger mechanism causes the spare tire to act like a piston, creating pressure in the heated cylinder and injecting glue through the nozzle onto the work surface.
The heating chamber is a metal cylindrical container containing a so-called heating unit, consisting of a heating element. It is the size of the heating chamber and the power of the heating element that determines the volume of the adhesive mass ready for use, that is, the productivity of the tool. Therefore, when answering the question of which glue gun to choose for handicrafts, you need to take these characteristics into account.
Power consumption
The power consumption of the heating element of a glue gun largely determines the rate at which the adhesive turns into liquid and affects the amount of electrical energy consumed. Thus, devices for professionals can consume 300 W or more, and guns for handicrafts are limited to 30 - 150 W.
Some manufacturers produce heat guns with power regulators. Then, at the start of operation, the device consumes 200 W, entering the operating state with a power consumption of 40 W, and while waiting, it reduces requests to 15 W.
However, the speed of “melting” of the adhesive composition may not affect the performance of the tool at all, since it is necessary to take into account the capacity of the heating chamber.
In the case when the heating element is capable of providing operating temperature, and there is a sufficient amount of adhesive in the heating reservoir, the power of the device can be ignored.
When trying to find the answer to the question of which glue gun is best for needlework, you should focus not on its power, but on its performance.
In addition, crafts using a glue gun can be made from different materials, some of which are quite sensitive to high temperatures.
Thus, for polymers, paper or fabric, low-temperature adhesive compositions. Moreover, for such rods special guns have been developed or tools with the ability to adjust the temperature must be used, which is often reflected in such a characteristic as the price. A glue gun for needlework must be selected taking into account various parameters.
The World Wide Web opens wide choose online resources where you can buy gun glue for needlework, in sticks various diameters, colors and lengths.
Crafts made with a glue gun are often true works of art, and many craftswomen have appreciated the capabilities of this tool. It is convenient and safe, and the results of the work created using a glue gun are simply amazing.
Besides:
- the adhesive composition for hot-melt guns is less toxic and does not emit unpleasant odors;
- replaceable nozzles allow you to work in places where in the usual ways getting there is very problematic;
- correct inaccuracies, since when heated, parts are easily detached;
- glue sticks retain their properties excellently for a long time;
- the polyurethane substance sets quickly and firmly;
- seams created with a glue gun are excellent at resistant to moisture;
- allows you to firmly bond both synthetic and natural materials.
However, you should be careful, as you can burn your hands if used incorrectly. It is not recommended to use the adhesive properties of the tool on thin synthetic materials or polyethylene.
The cost of a glue gun for handicrafts depends on its power, the possibility of using various temperature conditions and types of rods suitable for this model.
You can buy a glue gun for handicrafts in specialized online stores, in the same place where glue guns are sold, in this case, you won’t have a choice special labor, it is important not to miss some nuances.
What to look for when purchasing
Having decided where to buy a hot glue gun for handicrafts, first of all you should pay attention to its technical characteristics:
- power;
- melt operating temperature;
- productivity, which in the documentation is often referred to as the speed of operation, that is, the supply of adhesive;
- power options.
However, as already noted, the performance of a tool is usually more important than its power, and it is this indicator that will be the main one for determining the category of the tool. As for other parameters, they can significantly affect how much a glue gun for handicrafts costs. And this is from 250 rubles and above.
Undoubtedly, the Internet allows you to compare prices on resources where you can buy a hot glue gun for handicrafts, but it is useful to know the features thanks to which you can make the best choice.
So, if you have to use the gun periodically, then there is no point in purchasing an expensive modification that can support high temperatures, for home creativity, devices with chamber heating up to 165-170˚ are quite suitable.
In addition, you should not buy a heat gun with the ability battery life, a work of applied art can be created by a powered tool.
However, before deciding which glue gun is best for needlework, you need to familiarize yourself with its capabilities:
- switchable temperature mode;
- the presence of electronic regulation, eliminating the possibility of overheating;
- determining the state of readiness for work;
- presence of a push-button switch on the body;
- work area lighting;
- presence of an inspection window on the body;
- special trigger designs;
- possibility of changing nozzles;
- presence of a nipple on the nozzle;
- the presence of a stand leg;
- complete set of the instrument with a special case and a set of rods.
It is worth noting that, despite big choice similar tools industrial production, and a fairly affordable price, craftsmen, if possible, are quite capable of making a heat gun with their own hands.
How to make a heat gun yourself
Certainly, homemade instrument will not have the capabilities of industrial analogues, however, there are situations when such a device is urgently needed.
In this case, for those who have wondered how to make a glue gun on their own and quickly solve this problem, you will need:
- a roll of non-stick tape;
- tin sheet that can be cut from ordinary tin can;
- coil of copper wire;
- wooden block with a section of 2×4 cm;
- small household boiler;
- silicone rod.
First of all, a wooden handle is made, for which the length of the handle of the boiler is measured, to its working part. It is about seven centimeters. It is this value that is measured twice on a wooden block and two parts are sawed off.
Then, using a hacksaw, stepping back half a centimeter from the edges, make two longitudinal cuts on one side of each of the resulting blanks.
The depth of the cuts should completely recess the handle of the boiler after the excess wood has been removed from the grooves with a chisel.
The boiler is insulated from wooden surface Teflon tape and placed in the handle box, after which both parts are fastened with self-tapping screws or insulating tape.
The main part is ready.
Now, it is necessary to manufacture a nozzle nozzle and a cylindrical heating chamber. To do this, the silicone rod is wrapped in half a tin sheet cut from a can. The resulting cylinder should fit freely into the boiler spiral.
Using pliers, a funnel is made from the remaining part of the tin sheet, which should fit tightly with its wide end onto the cylinder of the heating chamber.
The connected parts, threaded into the coil of the boiler, are firmly fixed with copper wire.
After inserting the glue stick into the tool, you can start working.
It is important to note that a glue gun that uses a boiler as a heating element cannot operate directly from the mains. To connect the device, you need a special power regulator, which can be used to control the heating of the device.
Undoubtedly, homemade heat gun will not be able to replace industrial designs, and most likely will not be useful to home craftswomen in their creativity, but will help in carrying out urgent repair work he is quite capable.
A glue gun is one of the most commonly used tools in the house. With its help, we fasten, insulate, and create homemade products. What if you try to create a glue gun yourself?
See how to make a glue gun with your own hands:
So, to create your own glue gun we will need:
- Teflon tape or other non-stick coating,
- a piece of tin that can be cut from a tin can,
- copper wire,
- silicone rod,
- wooden block,
- an ordinary small boiler.
The materials are ready, you can start making a glue gun.
The first step is to make a wooden handle. To do this, you need to measure the lower part of the boiler, which, as a rule, is 6-7 centimeters and transfer the dimensions to a wooden block. You should pay attention that the dimensions are transferred twice, since the handle will be made of two parts. Then all that remains is to cut off two parts and make a recess small size so that both parts of the handle can be attached to each other and the middle of the boiler does not interfere. Finally, you can slightly round the handle so that the handle is comfortable to hold in your hand.
The wooden handle is ready. The next thing you need to do is wrap the middle part of the boiler with Teflon tape so that it does not heat the wood, and then fasten the two parts of the handle using self-tapping screws or electrical tape.
The first piece should be wound around a silicone rod, and from the second cut a separate piece 5 centimeters wide and 7 centimeters long. From this piece you need to create a small bag and attach it to the first piece, carrying both pieces through the passage at the bottom of the boiler, winding them with copper wire to fix them.
The cool gun is almost ready. To use it, just connect the gun to an outlet, wait until it warms up and lightly press on the silicone rod.
