Frequently Asked Questions
What products do you specialize in?
We are piezoelectric wafer specialists with over 30 years of experience. We were the first to work with single crystal quartz in China and have expanded to LiNbO3, LiTaO3, quartz glass, LGS, and CTGS materials. We export millions of quartz blanks annually with superior angle precision in AT, SC, and IT cuts.
Can you accept product customization?
Yes, we offer complete customization and can fabricate according to your specifications. Our experienced team can provide technical recommendations and we maintain standard wafer inventory for immediate delivery.
Can you deliver via our courier agent?
We support shipping through your preferred courier (DHL, FedEx, UPS, etc.) using your account. We optimize packaging to minimize shipping costs, or we can arrange freight with our established courier partnerships.
How do you guarantee product safety during shipping?
