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 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 can fabricate wafers according to your specific requirements. Our extensive experience with piezoelectric wafers allows us to provide valuable suggestions if you're uncertain about your specifications. We also maintain standard wafer inventory for immediate availability.
Can you deliver the goods via our courier agent?
Yes, we recommend using the courier service you're most familiar with (DHL, FedEx, UPS, etc.). We can ship using your account and will package products safely in optimal sizes to minimize shipping costs. We also offer competitive freight rates with international courier companies.
How can you guarantee we get what we want safely?
We understand that wafer products are fragile and valuable. We use adequate packaging with buffer sponge in proper cartons to prevent damage during transit. Please follow our acceptance check procedure, and if any issues occur despite our precautions, we will provide replacements or refunds when proper documentation is provided.
Can we visit your factory?
Absolutely. Factory inspections are important for large quantity purchases and long-term partnerships. We welcome face-to-face discussions and have hosted numerous global clients. During the COVID-19 pandemic, we've successfully conducted videoconferences with international buyers.
Acceptance Check Procedure
- Products are fragile and adequately packed with "fragile" labeling
- Upon receipt, handle with care and inspect outer carton condition
- Photograph the packaging before removing contents
- Open vacuum packages only in clean room environments
- If damage is found during transit, photograph or video immediately
- DO NOT remove damaged products from packaging boxes
- Contact us immediately with documentation for resolution
