Frequently Asked Questions
What are the products you mainly work on?
We specialize in piezoelectric wafers and were the first to work with single crystal quartz in China approximately 30 years ago. Our expertise extends to 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 and can fabricate according to your specifications. Our experienced team can provide technical recommendations if you're uncertain about material selection. We also maintain standard wafer inventory for immediate availability.
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 management services with discounted international courier rates.
How can you guarantee we get what we want safely?
We employ robust packaging with buffer sponge and fragile labeling. In case of transit damage, we provide replacements or refunds when you follow our documented acceptance check procedure.
Acceptance Check Procedure
- Handle products with care upon receipt and inspect outer carton condition
- Document packaging condition with photos before removing contents
- Open vacuum packaging only in clean room environments during application
- If damage is detected, photograph/video immediately without removing from packaging and contact us for resolution
