Hello dear readers and homemade products!
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
– Pliers, nippers, hammer
– Screwdriver with a set of bits
So, a long wooden block will serve as a handle, on the sides of which you need to make grooves for wires.
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.
< img class = "aligncenter" alt = "How to make a simple soldering iron (stapler) for plastic" src = "https://usamodelkina.ru/uploads/posts/2021-05/1620519611_ppl-014.jpg"/> The stripped ends of the power wires are inserted into these holes. 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.
The wires are fixed in the grooves with a second glue.
Now a terminal block is put on each nail and fixed on it. In this case, the nail should be clamped with only one screw, and not be too long.
The device will be powered from 12V 6A power supply .
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.
The positive wire from the power supply is soldered to one of the terminals of the coil, and the common terminal of the relay.
One of the heater wires is soldered to the normally open relay pin.
< a href = "https://usamodelkina.ru/uploads/posts/2021-05/1620519620_ppl-056.jpg" rel = "prettyPhoto"> The negative wire from the unit is connected to the second wire of the heater.
A two-wire thin wire is soldered to the pins of the clock button.
The first end of this wire connects to the remaining terminal of the coil, and the second to the negative wire twist.
It remains to fix the button on the holder, fix the wires, and hide the relay in a small case.
Tubes from thick syringe needles will serve as contacts for the staple.
These tubes are fixed in the terminals on the second screw, and the device is ready.
The author makes the staples from a thick nichrome wire taken from an old heater from a hair dryer. You can also use factory staples for a plastic stapler .
A homemade staple needs to be given a zigzag shape, like purchased staples.
The bracket is easily inserted into the tubes, and such an electrical contact will be enough.
When you press the button, the relay turns on, and the bracket heats up in just a second. < br> It is enough to press the bracket against the plastic and melt it in half the thickness. After that, the holder is easily detached.
Excess staple ends must be removed by cutting them off with wire cutters.
Of course, those who need such a tool very often will either have to improve the proposed design , or buy a factory hot stapler for plastic .
I thank the author for a simple “hot stapler” for welding plastic.
Good mood, good health, and interesting ideas to all!
