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, CTGS and other materials. We are the ultimate choice for piezo quartz suppliers, exporting 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 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 availability.
Can you deliver the goods via our courier agent?
Yes, we can ship using your preferred courier service (DHL, FedEx, UPS, etc.) under your account. We optimize packaging 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 use specialized packaging with buffer sponge and fragile labeling to protect these delicate wafers during transit. However, accidents can occur, so please follow our acceptance check procedure. If damage occurs during shipping and you follow the checking steps, we will provide replacement or refund.
Acceptance Check Procedure
- Handle all packages with care upon receipt
- Inspect outer carton condition before opening
- Check internal packaging alignment and photograph before removal
