FAQ


1.Q Are you a manufacturer, or a trading company?
A: We are an OEM/ODM manufacturing company.
2.Q:What's the delivery time?
A: 5 -7working days by express.
3.Q: Are there differences among zirconia ceramics?
A: Differences among zirconia ceramics can occur with the level of purity of zirconia;
grain size, trace elements and stabilizing compounds; and consistency of formulation.
Differences can exist in shrinkage from batch to batch because of differences in the
coefficient of thermal expansion (CTE).
4.Q: Do you provide samples ?  Is it free or extra ?
A: Yes, we could offer the sample for free charge but do not pay the cost of freight.
