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 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 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 availability.
Can you deliver the goods via our courier agent?
Yes, we can ship using your preferred courier (DHL, FedEx, UPS, etc.) via your account. We optimize packaging to minimize shipping costs. Alternatively, we can handle freight arrangements using our established courier partnerships.
How can you guarantee we get what we want safely?
We use specialized packaging with buffer sponge and fragile labeling. Please follow our acceptance check procedure: inspect outer carton condition, photograph packaging before removal, open vacuum packages in clean rooms only. If damage occurs during transit, document immediately without removing products from packaging and contact us for resolution.
