Engineering Expertise & Manufacturing Excellence
Kavri Quartz Product Co., Ltd. is a specialized manufacturer of short-wave tungsten halogen heating lamps, carbon infrared emitters, and fused quartz components based in Donghai, Lianyungang City — the renowned silicone and quartz capital of China. Backed by verified regional supply chains and 13 years of platform verification, our products are engineered to provide maximum thermal efficiency, exceptional mechanical durability, and strict dimensional tolerances.
Our halogen infrared heating tubes are manufactured using optical-grade fused silica glass envelopes filled with precision halogen cycle gases to eliminate tungsten evaporation and envelope blackening. With an operational lifetime exceeding 5,000 hours, they provide consistent radiant flux required by advanced OEM machine builders in Germany, the Netherlands, Japan, Korea, and the United States.
Rapid Thermal Response: Full rated output reached within 1 to 2 seconds, minimizing machine idle time and energy consumption.
Directional Reflectors: Half-coated 24K gold or white ceramic backings concentrate radiant heat onto target substrates without bulky secondary reflectors.
Extensive Customization: Tube diameter (10mm, 12mm, twin-tube 11x23mm), heated length up to 3000mm, voltages from 12V to 480V, and wattage up to 6000W.
Export Quality Control: Every batch undergoes full filament centering verification, resistance measurement, high-voltage leakage testing, and impact-resistant export crating.
