How to make the simplest soldering iron (stapler) for plastic

Hello dear readers and homemade products!
How to make a simple soldering iron (stapler) for plastic There are a huge number of products in the modern world made of plastic. This lightweight and strong enough material is strong enough, but any part can break or crack. Usually, all sorts of cases, handles, and other parts, which are not subject to special temperature requirements, are made of low-melting plastics such as ABS.
Repair of cracks by gluing or fusing parts together is not always effective. Such methods do not work well on products subject to mechanical stress and are more likely to break in the same place.
Such problems are very often encountered in auto repair shops, especially when restoring cracked bumpers and other elements. In this case, the craftsmen use a special “hot stapler” for plastic , with the help of which the metal staple is heated and fused into the thickness of the plastic. Thus, a rigid connection is created.
In this article, the author of the YouTube channel “Mextraf” will tell you how you can make a reinforcing stapler for plastic.
This tool can be made in a few minutes at home. Of course, such a device does not pretend for daily professional practice, but it is quite suitable for periodic repairs.
Materials necessary for homemade products.
– 12V relay
– 12V 6A power supply
– Nichrome wire
– Staples for a stapler for plastic
– Super-glue 502, a wooden block
– Flux, solder, wires, terminal blocks.
Tools used by the author.
– Electric soldering iron with temperature control
– Screwdriver
– Pliers, nippers, hammer
– Screwdriver with a set of bits
Manufacturing process.
So, a long wooden block will serve as a handle, on the sides of which you need to make grooves for wires.
 How to make a simple soldering iron (stapler) for plastic In the front of the holder, the craftsman prepared a pair of shallow holes. You can drill them, or hammer in nails and pull them out.

After that, two cloves with eaten caps are hammered into the holes. This creates a fairly good connection between the wire and the stud itself.

In order to be able to turn on and off the heating of the staple directly from the handle, you need a powerful switch, because the current in the circuit is large.
Instead, you can put a small clock button, and with its help turn on the relay , and supply power to the bracket.

You can also use factory staples for a plastic stapler .
A homemade staple needs to be given a zigzag shape, like purchased staples.

After that, the holder is easily detached.

I thank the author for a simple “hot stapler” for welding plastic.
Good mood, good health, and interesting ideas to all!
