Can an electric soldering iron be connected to a plastic toy? I often sell toys. Do you have any tips for welding plastic toys? Mainly to make the surface smooth. The commonly used electric soldering iron is too high to solder. Generally, the temperature is at least 270 degrees and the high temperature can reach 420 degrees. At this temperature, plastic toys are burnt at once and cannot be sold.
Generally speaking, there are two methods:
1 is to fill the gap with repair glue; 2 Use a special electric heating rod to heat the same plastic for repair.
Dogs eat plastic traps. One advantage of this thing is that they will spit out what they can't digest. Too much is not enough. If it is too little, let it vomit on its own. Take it to the hospital for surgery.
Plastic toys are no good. Try 502 or something.
What is toy plastic? Plastic 1. The main component of plastic toys is resin.
2. Raw materials of plastic toys: materials with high molecular synthetic resin (polymer) as the main component and various auxiliary materials or additives, which have plasticity and fluidity under specific temperature and pressure, can be molded into a certain shape and keep the shape unchanged under certain conditions;
3. Polymer: refers to the pure substance or polymeric substance produced in the process of polymerization. Both natural resin and synthetic resin belong to polymer, referred to as polymer for short;
4. Plastic has good insulation performance against electricity, heat and sound: excellent electrical insulation, arc resistance, heat preservation, sound insulation, sound absorption, vibration absorption and noise elimination efficiency.
Most of the raw materials of plastic toys are extracted from some oil, and some of the most familiar PC materials are extracted from oil, which smells like gasoline when burned; ABS is extracted from coal, and it will smoke when burned. POM is extracted from natural gas, which will have a very smelly gas smell when burned.
Plastic welding skills include ultrasonic plastic welding technology. Welding, embedding, spot welding, forming and cutting.
Plastic welding method:
1) hot plate welding
Pressure welding method for softening joint surface by using heat generated by hot plate.
2) Vibration welding
Pressure welding method for softening joint surfaces by heat generated by friction.
3) Ultrasonic welding
A pressure welding method for thermal softening of joint surfaces by kinetic energy of intermolecular mechanical vibration at ultrasonic frequency.
4) High frequency welding
Pressure welding method for softening joint surface by using heat generated by high frequency electric field.
5) laser welding
A technique for welding two molded products by laser energy.

How to play with a plastic crossbow? In modern times, crossbows have the following advantages over guns:
1, mute (micro sound) during transmission, which is beneficial to sound masking.

(3) There are no shell casings when launching. If you pull them out after killing, you can leave no physical evidence. )
(Disadvantages:
1, which is bulky and inconvenient to carry.
2. Accuracy, firing rate and range are not as good as rifles. )
