(When the temperature is too high, the magnet will affect the magnetic pull of the magnet) If you need to work at high temperatures, please contact us to select a higher specification neodymium magnet model for customized shuttering magnet assembly;
- Handling switches: Avoid excessive force when operating the shuttering magnet box switch. If necessary, try to hit the switch pressure head with a rubber hammer. Long-term use of an iron hammer will damage the internal structure of the magnet box.
- Avoid overloading: Distribute the load evenly on multiple shuttering magnets to avoid exceeding the specified load capacity of a single shuttering magnet. Overloading will weaken the magnetic force and cause premature wear and damage.
- Avoid violent impact: Prevent the shuttering magnet from falling and hitting. Violent physical shocks can damage the internal components of the magnet and reduce its effectiveness.
Maintenance after use:
After using the shuttering magnet, it is very important to perform maintenance to keep it in good condition for future use. Here are the steps to follow:
- Keep it clean, wipe the surface of the shuttering magnet clean after demoulding, and avoid debris from entering the inside of the shuttering magnet box. If foreign matter enters, the magnetic force will be affected. Remember that complete drying after cleaning can minimize rust and corrosion.
- Damage inspection: After each use, check the shuttering magnet for signs of wear or damage. Address and repair it in time to prevent further damage and ensure the reliability of the prefabricated magnetic box.
- Proper storage: Store the shuttering magnet in a dry, cool place and away from unnecessary metal and electronic equipment. Make sure that the ambient temperature is not higher than 70℃ when the shuttering magnetic assembly is stored, and there is no corrosive medium around. Long-term exposure to harsh and high-temperature environmental conditions will accelerate the demagnetization of magnets and affect their service life.
- Regular maintenance: If you expect the shuttering magnet box to be unused for a long time, the magnetic box should be cleaned and coated with anti-rust oil, and checked regularly.
