1. Are you a factory?

    Yes, we're a factory producing industrial ceramics professinally. Our main products are alumina ceramics, zirconia ceramics and sic ceramics.


2. What's the price for it?

    It depends. Prices are caculated by the drawing size and structure.


3. How about the delivery?

    Generally speaking, a ceramic production needs about 30 days to finish. Some special products maybe take a longer time. For some simple products, maybe 10-15 days is ok.


4. How's the packing?

    The usual packing is cartons, wooden cases, or pallets. Ceramics are fragile products, will use some breakage-proof

materials to protect them.


5. Can you do the finish maching?

    Yes, we have lathes, grinding machines, milling machines, carves-milling machines to make sure products' accuracy.
