We are recognized as piezoelectric wafer specialists with over 30 years of experience. We were pioneers in Single Crystal Quartz manufacturing in China and have expanded to include 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.
Yes, we offer complete customization services and can fabricate according to your specific requirements. Our experienced team provides technical guidance for optimal wafer selection. We also maintain standard wafer inventory for immediate availability.
We accommodate shipping through your preferred courier accounts (DHL, FedEx, UPS, etc.) and optimize packaging to minimize shipping costs. We also offer freight management services with competitive international shipping rates.
We implement comprehensive protective packaging with vacuum sealing, buffer sponge, and reinforced cartons. All shipments are clearly marked as fragile. Please follow our acceptance check procedure to verify product condition upon receipt.
Factory inspections are welcome for significant orders and long-term partnerships. We have hosted numerous international clients and also offer virtual factory tours via videoconferencing for remote evaluation.
- Handle all packages with extreme care upon delivery
