-Long term use temperature of 1200 ℃, short-term can reach 1450 ℃
-Excellent UV infrared transmittance performance (transmittance>90%)
2. Precision manufacturing process
-Formed by electric melting or gas refining method, with strict control of internal bubbles and impurities
-High dimensional accuracy (diameter tolerance ± 0.5%, roundness deviation<0.3%)
-Surface smoothness can be customized (polished, frosted, flame treated)
-Can perform secondary processing such as cutting, drilling, sealing, flange connection, etc
3. Stable quality assurance
-Each batch of products undergoes bubble degree, stripe degree, and stress testing
-Compliant with international standards such as ASTM, ISO, JIS, etc
-Provide material reports and performance testing data
-Strong anti crystallization ability and significantly longer service life than the industry average

The key problems we can solve
1. Replace expensive imported products
To provide customers from Europe, America, Japan, and South Korea with products of equal quality but more competitive prices, and to shorten delivery times (4-6 weeks for regular orders and 2-3 weeks for urgent orders).
2. Break through technological bottlenecks
Solve technical problems encountered by customers in the production of oversized quartz products, such as poor uniformity, easy deformation, and insufficient temperature resistance. We use segmented molding and special annealing processes to ensure that 800mm diameter products still maintain excellent thermal stability.
3. Match complex system integration requirements
Provide pre assembled quartz components for equipment manufacturers to reduce on-site installation difficulty and risk of damage. For example, the 700mm quartz tube with flange connection port provided to a European photovoltaic equipment supplier reduced its equipment assembly time by 40%.
4. Coping with the challenges of harsh working conditions
Special formula materials can resist strong corrosive environments such as fluoride and chlorine gas, extending their service life in semiconductor etching equipment. Actual testing shows that our 650mm quartz tube has an extended lifespan of over 30% compared to conventional products in the same corrosive environment.
