FAQ

 

Q1:How fast can I get a reply?
A: You will receive our reply within 15 minutes during our work time 08:00-18:00(UTC-8).

Q2:What information do I need to supply when I have a inquiry?
A: In order to get precise quotation on time,pls inform us following details when you send inquiry to us: Dimensions or drawing;Grade of Material;Magnetized direction; Surface coating(if necessary) ;Quantity and delivery terms.
If you have don't have above information, you can inform us the application of the magnets, our technician will provide
professional advice for you.

Q3:Can you offer customized size and shape?
Yes, we could produce customized size,shape magnets according to customers' requirements.

Q4:Can I have a free sample before mass production?
A: Yes. We could offer free samples if the magnets are in stock but you need to pay the delivery cost. It may take minimum 7 days for production if your size is out of stock.For neodymium magnets, we have many different size samples in stock.

Q5:Can magnets could be shipped by air or by express ?
A: We could ship the magnets by air or by express with our magnetic shield package.

Q6. How about the quality of the magnets?
A: To ensure the quality of the products, every production procedure is inspected strictly by the professional QC team from all aspect.Besides,Alibaba Trade Assurance order will protect your payment, and make sure that we deliver on time and manufacture quality products as required.

Q7: Will the magnetism be weaker after use years?
A: Yes, magnets do weaken over time.If you store permanent magnets correct, neodymium magnets will likely lose less than 1% of their flux density over 100 years.The magnetism decline is neglect, that's why we call it Permanent Magnet.
