Frequently Asked Questions
What are the products you mainly work on?
We specialize in piezo 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 are the ultimate choice for piezo quartz suppliers, exporting millions of quartz blanks annually with superior angle precision for AT, SC, and IT cuts.
Can you accept product customization?
Yes, we can fabricate wafers according to your specifications. Our extensive experience with piezo wafers enables us to provide valuable technical suggestions 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 recommend using your preferred courier service (DHL, FedEx, UPS, etc.) and can ship via your account. We optimize packaging to minimize shipping costs while ensuring product safety. We also offer competitive freight arrangements through our established relationships with international courier companies.
How can you guarantee we get what we want safely?
We employ comprehensive protective packaging with buffer sponge and fragile labeling to safeguard these delicate and valuable products. In case of transit damage, please follow our acceptance check procedure for prompt resolution through replacement or refund.
Acceptance Check Procedure
- Handle products with care upon receipt and inspect outer carton condition
- Carefully open outer carton and check packaging box alignment
- Document packaging condition with photographs before removing products
- Open vacuum packaging only in clean room environments during application
