5. FAQ
- Is it possible to make customized irregular shape magnet?
Yes,we can do varied shape magnet,customized shape and drawings are welcome.
- What is the strength of magnet?
In theory, Magnets can suck up 64 times is equivalent to its own weight of iron.If you have the strength request,we can design the magnet size for you.
- What is the magnet working temperature?
We can do the magent as your working temperature demand range of 80°c to 230°c
- Low lost weight and Salt Spray test available?
Yes, We are equipped with complete equipments for plating and function test.
- What is the delievery time ?
It depends on product shape, plating technology and amount.In general, The Small lot production in usual shape is about 7 days after the confirmation.Mass production or irregular shape with epoxy or cadimium plating will take longer time.
