There is a problem with the newly bought ring mold.

The ring mold of a certain brand just bought a few days ago, used less than a week, made more than 200 tons, and became like this. Please help us to see if it is the quality problem or our operation problem. Thank you attachment: you need to log in before you can download or view the attachment. No account number?

Or is it something else? It is recommended to buy a better one, hehe ~ ~ Wicker's or Shende, whatever is appropriate! But the price can also ~-or buy it, really, now everything has defective products-the quality is too poor, only a few days to buy stainless steel, ah, even alloys should not be like this, find manufacturers to accompany! -it must be a quality problem.

The quality is good and the price is excellent. 13961245892-this post was last edited by hl43802960 at 2009-12-17 13:56 and replied, "the zgjsyzdxq profile is not very clear-you can go to the manufacturer-is it 508D? liyangzm added the following at 2009-12-17 13:41 Yours is also expensive-this post was last edited by hl43802960 at 13:52 on 2009-12-17 13:52 and replied, "the hl43802960 profile is not very clear attachment: you need to log in before you can download or view the attachment.

Most of this kind of problem is that there is a problem with the material of the ring mold, and the manufacturer generally guarantees how many tons of material can be produced, which can be replaced by the manufacturer.
