Magnets FAQ

Q: I was replacing the membrane on my HD Press and the magnet broke. What can I do to prevent this in the future?

A: Neodymium Magnets are very strong, but also very brittle. They should be handled with care. Avoid releasing magnets to press more than 1-2" away. These magnets are very powerful and can accelerate a great speeds toward each other and toward ferrous material. When these magnets come together quickly, they can shatter and break sending particles at high speed. These magnets can also pinch strongly if allowed to come together against the skin. See warnings below for more information.

Q: How do I separate magnets that are stuck together?

A: Use a flat surface with an edge such as a table or countertop. Hold the magnet roll on the table. Push one magnet at a time off the end of the roll over the leading edge of the table down and away. Keep it away from the other magnet(s) once separated.

Q: To what temperature can Neodymium magnets be subjected before they start losing their magnetic force? 

A: 176 degrees Fahrenheit.

Q: How long will Neodymium magnets last? 

A: 400 years...if not subjected to sharp impacts or higher than rated temperatures. ;)

Q: What else do I need to know about the magnets used with the HD vacuum press?

A: Neodymium Magnets are very strong for such a small magnet.  Please handle them with care to prevent personal injuries, property damage, and damage to the magnet itself.  Our vacuum formers are usually used in an adult, professional environment, but just in case they are not, here are some hazards you may not be aware of. 


WARNING - please read before handling magnets


Children should not be allowed to handle neodymium magnets -  Small magnets are a CHOKING HAZARD and should not be swallowed or inserted into any part of the body. This could result in death. Magnets are not toys and are for adult use only !


Pace-makers may be damaged or switched to "Test Mode" due to strong magnetic force. Please keep minimum of 3ft from pace-maker or other medical implants. Consult your physician regarding safe distances for your device.


Magnets are brittle - may break or splinter in a collision. Wear gloves and protective glasses when handling due possibility of splinters flying from the magnets.

Do not cut, saw or drill the Neodymium magnets. Magnets will break - dust from magnets is very flammable. 

Do not burn magnets - burning  will create toxic fumes.

Do not allow two magnets in close proximity to each other or other ferrous metal material when handling to avoid pinching hazard to fingers.  Serious damage could occur.


Strong magnetic fields of magnets can damage items such as electronics, credit cards, computers, watches, hearing aids, speakers, and other electronic devices. Keep items away from magnets
