Pot Magnet Manufacturer introduces the manufacturing process of magnets:
1. First make a sand mold that requires a magnet shape, and then you can cast the magnet. The materials include copper, cobalt, sulfur, nickel, iron, aluminum, and titanium. Put the metal into an electromagnetic stove and heat it to over 1600°C to melt all the metal into a liquid.
2. Pour the solution into the sand mold, and the sand mold will burn because the gas in the hardened sand is flammable. Use a hammer to pry open the casting mill, let air enter the casting mill to cool the material, and let the gas burn out. Separate the metal from the sand block, and the metal after casting is still an ordinary iron block without any magnetic force.
3. Tie the metal parts to the copper pipe and put it into a larger pipe. Place the copper pipe in the middle position, and close the sides with silica sand. Seal both ends with concrete to expose the two ends of the copper pipe.
4. Put it into the furnace and heat it at 700℃ and take it out. Fix both ends of the copper pipe with clamps, pass low-voltage and high-charge current, and then take out the metal parts. This step has made the metal parts slightly magnetized and the direction of the magnetic field has been correctly established.
5. Make the magnet effective through the magnetizing machine, and the machine will transfer the magnetism to the metal through the current to make it magnetism. After the alternating current is applied, the capacitor is first charged with high voltage (energy storage), and then discharged through a coil with very small resistance. The peak current during discharge is very high, reaching tens of thousands of amperes. The strong magnetic field generated by electromagnetic can make metal permanent magnetization.
