How to bend a plastic panel with your own hands. Decorating walls with plastic PVC panels by gluing them. Technology for installing PVC panels with glue
PVC pipes They are increasingly used as a source material for the manufacture of various crafts and crafts. Sometimes craftsmen give them an ornate curved shape and the final work after applying the finishing coating does not even resemble the finish raw material. In this master class we will demonstrate a similar technique to you.
Materials
To bend a PVC pipe you will need:
the pipe itself;
durable tape;
sand;
funnel;
metal container;
gas or electric stove;
protective gloves;
knife or scissors;
saw or hacksaw, as well as sandpaper.
In addition, you will need a pipe bending device. IN in this case a piece of plywood with dowels embedded in the thickness was used.
Step 1. Usually, a gas torch is used to bend pipes, but with its help you can give the pipe only a slight bend and only small area.
It is difficult to process significant sections of such material in this way. This takes a lot of time, and besides, the pipes are often bent during work, which does not look aesthetically pleasing.
To bend a pipe, as you see in the photo of the final work, it requires uniform heating from the inside. For this difficult operation we use sand. So, first of all, you need to cut a piece of the required length from the PVC pipe and clean the edges of the cut.
Step 2. One end of the pipe must be sealed with tape. The tape should completely cover the hole.
Using a funnel, you need to pour sand into the pipe. Take enough of it so that the pipe is completely filled with it.
After measuring the required volume of sand, pour it into a metal bowl and warm it well. The sand should become hot.
Wear protective gloves on your hands. Using the same funnel, pour the prepared sand back into the pipe.
Cover the other end of the pipe with tape. This is necessary so that the sand does not spill out during work.
Leave the pipe like this for a couple of minutes. During this time it will warm up from the inside. The material will become soft and pliable.
While the sand is still hot, you can give the cut piece of pipe the bend or shape you need. After this, remove the tape and pour the sand back.
Once completely cooled, the pipe will hold the shape you gave it.

If you heat the plastic correctly, it can be easily bent, one of the options simple device For this we will consider below.
This device Can be used to thermoform plastics up to approximately 1/8 inch thick. This way it bends well polystyrene, polycarbonate and PVC.
The base of the entire device will be an MDF board, its size is unlimited, what size you need to bend, choose that size. An aluminum “U” shaped profile is well suited for the heat shield of the heating element; it can be purchased at any hardware store, suitable size 10*10mm,10*8mm. We screw the profile along the edge of the base sheet with self-tapping screws.
For the heating element itself, we need nichrome wire with a diameter of 0.2 to 1 mm.
Using the table “Calculation of nichrome wire for a heater”, you can see the maximum amperage for heating the existing wire diameter to the required temperature of 400-600 degrees.
We stretch the wire inside the profile; to adjust the height and direction, we use bolts with a head for a flat-head screwdriver. The wire should not touch the plastic workpiece, the distance depends on the size of your profile and can be 1-3 mm. To constantly tension the heated nichrome, we install a fairly stiff spring, for example from a printer.
For ease of use of the device, you can also install a switch, a connector for connecting a battery or power supply. It is very convenient to use a powerful adjustable power supply to smoothly regulate the incandescence (heating) of the wire. For example, this one: Adjustable power supply 4000W AC 220V adjustable 10-220V.
How to work: Place a sheet of material along the fold line over the hot wire and turn on the power. We hold it motionless until we notice that the bend has softened and begun to bend on its own. We quickly move the workpiece onto a flat table and bend it to the angle we need, hold it like this until it cools.
Many people wonder how they can bend PVC plastic pipes themselves. Indeed, in the process of installing heating and water supply systems, you very often have to deal with deformation of pipes, but many, not knowing how to do this, acquire a lot of unnecessary components, with the help of which they create bends and branches of the channel. At the same time, they spend almost a third of the allocated budget for creating the entire pipeline. A more rational and inexpensive way is to bend PVC pipes.
So, in order to bend a polyvinyl chloride pipe intended for heating and drinking water supply systems, it is necessary to remember and put into practice several well-known methods of influencing plastic products using heated air and a vaporous substance. In addition, in independent construction work ah there is a way to bend a PVC pipe using the included gas stove. So, let's talk about everything in more detail.
As for the handy method of bending plastic pipes, it consists in heating up exactly that section of the pipe that will bend. A home stove, or rather, one of its burners, can help in this matter. But when using this method of bending plastic pipes, you need to be vigilant and careful, since an open flame can damage not only the pipe, but also human hands. And in more serious cases lead to disastrous results. Therefore, there is always an alternative to everything that happens, regarding methods of bending PVC pipes, including.
More in safe ways creating any bend and direction of the pipe intended for supplying water are:
1. You can bend a plastic pipe using a technical hair dryer. To ensure the proper shape of the PVC pipe when it is heated, so that it does not begin the melting process, it is necessary to pour into its internal cavity a material that is resistant to elevated temperatures, and whose structure has the form of finely ground fractions. Such materials include both sand mass and salt mass. Using a construction watering can or funnel, pouring such materials inside a polyvinyl chloride pipe will not be difficult. Naturally, one end will need to be sealed with a stopper or barrier cap. Approximately, to fill a standard (length about 3 meters and diameter about 2 cm) plastic pipe intended for creating a heating system or water supply channel, you will need about one bucket of bulk material. Knowing all the calculations, you can purchase everything you need in advance and not worry about whether the available materials are enough or not.
2. Plastic pipe can be bent without the help of a technical hair dryer. This method involves heating bulk material (sand mass or salt mass) using oven. To realize your plan, you will need a baking sheet and a preheated oven. After the bulk mass has warmed up to the desired temperature, using a scoop and a construction funnel, it is necessary to pour it into the internal cavity of the plastic pipe. It must be taken into account that when choosing this method of bending a PVC pipe, you need to have a crow and a metal barrier cap.
An important nuance is to determine the required temperature, sufficient for bending plastic pipes, as well as polyvinyl chloride pipes, independently. In this case, you need to think logically. This issue can be considered using the example of a water heating tank. So, the tank heats the water, according to the recommendations in the instructions for the product, to a maximum of 75 degrees Celsius, but it is advisable to adjust the mode and set the heating temperature to 60 degrees. This is necessary in order to avoid the formation of precipitation on the walls of the tank during heating at high temperatures. So, by analyzing the available data, we can conclude that the required heating temperature of the bulk mass must definitely be above 80 degrees. There is information on the Internet that such masses need to be heated to at least 140 degrees and no more than 170 degrees, so this extreme temperature is considered the melting point of plastic and PVC products.
All methods of bending PVC pipes for water supply systems have been considered, and you need to make a choice only based on your wishes.
What methods can be used to bend PVC pipes intended for sewer systems?
Few people know what they are rigid PVC Large diameter pipes can generally be bent. You need to understand that not all types of such pipes can be bent. Moreover, you can only bend the pipe a little, but that's already something. In most cases, as practice shows, a plastic sewer pipe with a diameter of 1011 cm can be bent by a maximum of 25% using a technical hair dryer. Do not worry if relief formations in the form of folds appear on the outer surface of the PVC pipe after treatment with a technical hair dryer. Such formations do not impede the passage of masses through it, and also do not weaken the deformed areas.
Pipes made of polyvinyl chloride or plastic with a diameter of 56 cm can be easily created. For bending such products, a technical hair dryer is used or hot bulk materials technology is used. Before the process of creating bends, it is necessary to undergo a training exercise. There is no need to skimp on materials to hone your skills. Such training will help to achieve a good result at the end of the process of bending the desired plastic product.
The bending process itself sewer pipes made of plastic or polyvinyl chloride is not much different from the process of bending pipes for heating systems or water supply systems. Initially, it is necessary to heat the bulk material to 80-100 degrees Celsius, and then pour it into the cavity of the plastic product. Next, you need to wait some time for the PVC pipe to warm up at the intended bend. Once you have waited, you can begin to give it the desired look.
Today's construction technologies have reached the level of creating special bendable PVC pipes for sewerage systems. They are produced in different sizes and with different diameters. Therefore, when purchasing such a pipe, you can avoid imparting flexible properties to the pipe yourself. But the choice is always yours!
Quite often during construction work, when the owner makes major renovation, they face many problems that need to be solved using available tools. For example, quite often it is necessary to give a plastic product a curved shape. Of course, you can go to the store and buy a ready-made product, but the search for the most suitable product often takes a long time. Below we will try to figure out how to bend plastic at home.
The very concept of “plastics” unites a large number of natural or synthetic polymers that can easily deform and change shape when heated. After the material hardens, it will become solid again. We will use this property of plastic when answering the question of how plastic can be bent.
You can bend plastic in several ways. The best way to avoid breaking the material and create a bend at the required angle is to use a molding machine.
To bend the plastic you will need:
- molding machine;
- VAL board;
- silicone;
- industrial dryer.
Detailed instructions on how to bend plastic
If you need to bend polystyrene, you can prepare several tools. Make a mandrel from MDF (fibreboard). Assemble the mold and, depending on the width and length of the plastic part, adjust it to the appropriate size. Go over the surface with sandpaper to ensure there are no distortions.
Prepare the shell for the plastic silicone part using a molding machine. It will be needed to fix the flat workpiece on the mandrel and preserve its surface from scratches and chips.
Insert the plastic part into the shell, then secure it into the MDF mandrel and place it on the molding machine. After the unit warms up and the plastic begins to settle on the mandrel, taking the required shape, you need to wait 5-7 minutes. Carefully remove the part from the machine while wearing gloves. Then place it on a metal surface to allow the material to cool. Then remove the mandrel.
Bend plastic pipe much easier. Take an industrial hair dryer or gas burner, turn it on and point it at the place where you are going to make a fold. The distance from the heating device to the surface of the part must be at least 5 cm.
Rotate the pipes without stopping, otherwise it may catch fire. Heat it until the material is soft, then bend it. Hold the pipe in this position for a while to allow the plastic to harden.
Plastic slopes for windows or walls made of foamed PVC, you can bend it at the required angle, making frequent cuts along the radius. Then, having created the required shape, fix them with special glue. This way you will make a part with bends and extensions.
