Upgrade Your Systems with Our Piezoelectric Wafer Endcaps for Precision Engineering and High-Temperature Applications

Our quartz endcaps are expertly designed to provide superior thermal stability, chemical resistance, and optical clarity for demanding applications across semiconductor processing, laser systems, and industrial equipment. Crafted from high-purity fused silica (SiO₂), these endcaps withstand extreme temperatures (up to 1,200°C) and corrosive environments without deformation or contamination, ensuring long-term reliability in critical processes.

Key Advantages:

• Exceptional Purity: 99.99% SiO₂ content minimizes outgassing and particle generation.
• Precision Fit: Customizable dimensions (OD/ID/thickness) and surface finishes (polished or ground) for seamless integration.
• Thermal Shock Resistance: Maintains structural integrity during rapid temperature cycles.
• Optical Transparency: Ideal for UV/VIS/IR applications requiring unobstructed transmission.

Whether used as vacuum chamber seals, laser window protectors, or furnace components, our quartz endcaps deliver unmatched performance. Available in standard and bespoke designs with fast turnaround times, we support prototyping to full-scale production.

Packing and Shipping:

Our Piezoelectric Quartz Endcaps are carefully packed in a sealed and secure container with an anti-static layer and moisture barrier to ensure that it arrives securely and undamaged.

The container is then sealed and labeled with a unique identification number for tracking purposes.

We offer both domestic and international shipping options, with the latter requiring additional paperwork. We also provide a tracking number for all domestic shipments.

Founded in 1999, Hangzhou Freqcontrol Electronic Technology Ltd. is a China leading manufacturer of piezoelectric crystal wafers, substrates, components and single crystal growth. We, known as the "CQT Group" in global market, headquartered in Hangzhou, China, empowered by its manufacturing sites in Shanghai, Jiaxing and Deqin etc.

Our products are mainly used in RF Telecom, Semiconductor, Biotech, Optical engineering and frequency control industries. The monthly production capacity: 500K single quartz blanks (SC, AT, IT, FC, etc.), 20K quartz wafers (AT, ST, X, Z, etc.), 10K LiNbO3 wafers (3~8 inch), 10K glass wafers (Fused silica, Borofloat33, Corning, etc.), 8K LiTaO3 wafers (3~6 inch), and 100K filters/oscillators (VCXO, TCXO).

Our company vision is to be a reliable primary Microelectronic substrates supplier in today's world.

The CQT Group consists of five major plants with total floor area over 10,000 m². Our production machines include crystal growth furnace, wire saw, X-ray orientation, grinding machine, polishing machine, chamfering machine, CNC, REDOX chambers etc. Inspection equipment include Flatmaster 200, AOI, profilometer, optical imager, X-ray inspector etc. We are also equipped with Class 100 and 1000 clean rooms.

The CQT group is primarily known as the expert of hexagonal crystals, We master the manufacturing process of single & doubly rotated quartz blanks, and we can provide quartz of any orientation cut whether given by IRE , Miller index, Euler angle or conventional sign.

In addition to our leading quartz blank manufacturing capabilities, the last decade sees our major technological breakthroughs. We overcome the 3~6 inch ultra-thin wafer mass production barrier, obtained the reduction technology of black LiNbO3 & LiTaO3 wafers, and achieved 8 inch LiNbO3 wafer mass production successfully.
