Engineered to withstand extreme temperatures and harsh chemical environments in modern Thai manufacturing plants.
Lianyungang Southeast Quartz Products Co., Ltd., established in 2015, is located in Donghai County, Lianyungang City, Jiangsu Province—a national base for the silicon material industry. As a professional manufacturer integrating R&D, design, production, sales, and import & export trade, the company relies on the superior high-quality quartz ore resources in Donghai County, deeply engages in the deep processing of quartz glass, and has become a core supplier of quartz consumables for photovoltaic, semiconductor, laboratory, chemical, lighting, and other industries with mature production technology, a strict quality control system, and complete customized services.
The company has standardized production workshops, advanced quartz processing equipment, and a professional R&D team, with full-process production capacity from quartz raw material processing to finished product manufacturing. It can produce a full range of quartz products, including high-purity fused quartz tubes, quartz furnace tubes, quartz bell jars, quartz boats, quartz lamp holders, quartz crucibles, quartz instruments (beakers, condensers, distillers, etc.), and tri-acid purification equipment.
All products are made of high-purity fused quartz raw materials, featuring excellent high-temperature resistance (up to 1200℃), thermal shock resistance, corrosion resistance, high light transmittance, and good electrical insulation performance, which can meet demanding working conditions such as vacuum environments, high-temperature sintering, atmosphere control, and precision experiments.
Thailand's transition toward high-tech manufacturing under the "Thailand 4.0" initiative has spurred unprecedented demand for advanced thermal processing components.
The Eastern Economic Corridor (EEC) of Thailand, spanning Chonburi, Rayong, and Chachoengsao, is rapidly evolving into a major hub for semiconductor assembly, testing, and advanced packaging. Fused quartz furnace tubes are critical for silicon wafer oxidation and diffusion processes, demanding ultra-high purity (>99.99% SiO2) to prevent metallic contamination and ensure high chip yields.
Thailand has become one of the leading manufacturing bases for solar cells and modules in Southeast Asia. Solar cell production involves high-temperature phosphorus diffusion and annealing, where large-diameter quartz furnace tubes and quartz boats are indispensable. Our custom-sized tubes support thermal stability up to 1200°C, matching the intensive operations of Thai solar factories.
Leading academic and state research institutions in Thailand, such as Chulalongkorn University, Kasetsart University, and MTEC (National Metal and Materials Technology Center), are expanding material science research. This drives the demand for specialized, custom-designed small-bore quartz tubes and instruments for laboratory vacuum furnaces and chemical vapor deposition (CVD) setups.
Our custom quartz furnace tubes are specifically engineered to meet the operational demands of diverse Thai industrial sectors.
In the cleanrooms of electronic component manufacturers near Bangkok, quartz tubes act as the primary process chamber. They isolate silicon wafers from external contaminants during high-temperature thermal oxidation. The low coefficient of thermal expansion of fused silica prevents structural failure during rapid temperature cycling.
In Rayong's massive solar parks, heavy-duty quartz tubes are integrated into horizontal diffusion furnaces. These tubes carry quartz boats loaded with silicon wafers. Our tubes feature uniform wall thickness and excellent thermal shock resistance, ensuring consistent heat distribution and reducing downtime for Thai solar manufacturers.
Thailand’s traditional ceramics and advanced glass industries rely on industrial furnaces for sintering. Fused quartz tubes provide a clean, chemically inert barrier for atmospheric control (vacuum, nitrogen, or argon flow) during sintering, preventing oxidation of the processed parts.
For researchers developing advanced coatings or 2D materials in Thailand, our custom quartz tubes serve as CVD reaction chambers. We customize the tube ends with ground joints, flanges, or gas inlets to seamlessly connect with gas delivery and vacuum systems.
A professional manufacturer with over 10 years of experience in the quartz industry. Serving diverse high-tech applications globally and locally in Thailand.
Every quartz tube undergoes a meticulous manufacturing process using state-of-the-art machinery to guarantee absolute purity and dimensional accuracy.
Take a look inside our state-of-the-art facility where high-purity quartz products are precision-crafted.
Adhering to the philosophy of "Quality First, Customer Supreme, Innovation-Driven, Integrity Management", Lianyungang Southeast Quartz Products Co., Ltd. has established a complete quality inspection system. All products undergo multiple tests such as helium mass spectrometry leak detection, pressure resistance test, and purity test before leaving the factory to ensure stable performance, no impurities, and no leakage.
Meanwhile, the company provides flexible customized services, and can customize product sizes, structures, and specifications according to customers' equipment parameters and process requirements, quickly responding to personalized orders.
With reliable product quality, efficient delivery capacity, and thoughtful after-sales service, our products not only cover all provinces and cities in China but also are exported to many countries and regions in Europe, America, Southeast Asia, the Middle East, etc., winning wide recognition and trust from customers at home and abroad. In the future, the company will continue to deeply cultivate the field of quartz products, continuously improve technological innovation and production technology levels, and strive to provide global customers with higher-quality and more professional quartz product solutions, contributing to the high-quality development of high-end manufacturing and scientific research fields.
