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 LiNbO3, LiTaO3, Quartz glass, LGS, and CTGS. We export millions of quartz blanks annually with superior angle precision for AT, SC, and IT cuts.
Can you accept product customization?
Yes, we can fabricate according to your specifications. Our experienced team can provide technical recommendations if you're uncertain about your requirements. We also maintain standard wafer inventory for immediate delivery.
Can you deliver the goods via our courier agent?
Yes, we can ship using your preferred courier (DHL, FedEx, UPS) via your account. We optimize packaging to minimize shipping costs while ensuring product safety. We can also arrange shipping with our discounted carrier rates.
How can you guarantee we get what we want safely?
