We specialize in piezo wafers and were the first to work with Single Crystal Quartz in China over 30 years ago. We export millions of quartz blanks annually with superior angle precision in AT, SC, and IT cuts.
Yes, we fabricate according to customer requests and provide expert guidance for wafer selection. We also maintain standard wafers in stock.
Yes, we can ship using your preferred courier (DHL, FedEx, UPS) and pack products safely to minimize shipping costs.
We use adequate packaging with buffer sponge and fragile labeling. Follow our acceptance check procedure: inspect outer carton condition, photograph before opening, and contact us immediately if damage occurs.
Yes, factory inspections are welcome for large quantity purchases. We also offer videoconferencing for remote discussions.
- Handle with care and check outer carton condition upon receipt
- Photograph packaging before opening for documentation
- Open vacuum packages in clean room environments only
- If damage is found, photograph/video immediately and contact us
- Do not remove damaged products from packaging boxes
