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,****** 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.
