We are piezoelectric wafer specialists with 30 years of experience. We were the first to work with Single Crystal Quartz in China and now manufacture LiNbO3, LiTaO3, Quartz glass, LGS, and CTGS wafers. We export millions of quartz blanks annually with superior angle precision for AT, SC, and IT cuts.
Yes, we fabricate wafers according to customer specifications. Our experienced team can provide technical recommendations and we maintain standard wafers in stock for immediate delivery.
We can ship using your preferred courier (DHL, FedEx, UPS) via your account. We optimize packaging to reduce shipping costs while ensuring product safety. We also offer competitive freight rates through our international courier partnerships.
We use specialized packaging with vacuum sealing, buffer sponge, and fragile labeling. Follow our acceptance check procedure: inspect outer carton condition, photograph packaging before opening, and contact us immediately if damage is found without removing products from packaging.
Factory inspections are welcome for large quantity purchases and long-term partnerships. We also offer videoconferencing for remote discussions with international buyers.
