Precision and Durability Quartz End Caps for High-Temperature and High-Pressure Applications

Precision Engineered for Extreme Environments‌

Elevate your industrial and technological applications with our premium ‌Quartz End Caps‌, designed to deliver unmatched performance in the most demanding conditions. Renowned for their exceptional thermal stability, chemical resistance, and optical clarity, quartz end caps are the go-to solution for industries requiring reliability under extreme temperatures and corrosive environments.

‌Why Our Quartz End Caps Stand Out‌

• ‌Ultra-High Purity Material‌: Crafted from 99.99% fused silica, our end caps ensure minimal contamination, making them ideal for semiconductor processing, vacuum systems, and high-purity chemical applications.
• ‌Extreme Durability‌: Withstand temperatures up to 1,200°C and resist thermal shock, acids, and alkalis, outperforming traditional materials like ceramics or metals.
• ‌Customizable Designs‌: Available in diameters from 10mm to 300mm, with tailored shapes, thicknesses, and surface finishes (polished, ground, or coated) to meet precise specifications.
• ‌Broad Industry Applications‌: Perfect for laser systems, fiber optic communications, LED manufacturing, CVD/PVD reactors, and analytical instrumentation.

‌Engineered for Excellence‌
Our quartz end caps are precision-machined using advanced CNC and ultrasonic processing to ensure micron-level accuracy. Each unit undergoes rigorous quality checks, including helium leak testing, spectroscopy, and surface integrity analysis, guaranteeing airtight seals and flawless performance.

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.
