Frequently Asked Questions
What are the products you mainly work on?
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 include LiNbO3, LiTaO3, quartz glass, LGS, and CTGS materials. We export millions of quartz blanks annually with superior angle precision for AT, SC, and IT cuts.
Can you accept product customization?
Yes, we offer complete customization services. Our experienced team can fabricate wafers according to your specifications and provide technical guidance if needed. We also maintain standard wafer inventory for immediate delivery.
Can you deliver the goods via our courier agent?
We can ship using your preferred courier service (DHL, FedEx, UPS, etc.) via your account. Our packaging is optimized to minimize shipping costs while ensuring product safety. We also offer freight services with discounted international courier rates.
