JUNTENG is a manufacturer and supplier of professional Carbon Carbon Thermal Insulation Materials in China. We adopt three-dimensional weaving integration technology, which can withstand an extremely high temperature of 2200℃, has a low thermal conductivity, is resistant to thermal shock, has high purity and no impurities, and has excellent sedimentation effect. Its lightweight insulation performance far exceeds graphite soft felt and ordinary carbon felt. We can customize SiC anti-oxidation coatings and perform molding and cutting according to requirements, and it is widely used in the thermal insulation of photovoltaic single crystal furnaces, semiconductor diffusion furnaces, and high-temperature sintering furnaces.

JUN TENG's Carbon Carbon Studs are long-rod fasteners designed for high-temperature vacuum thermal fields — connecting large graphite components in photovoltaic single-crystal furnaces, semiconductor CVD chambers, and vacuum heat treatment equipment. Manufactured through 3D weaving and multi-cycle densification, they deliver stable fastening at 2200°C in inert atmospheres without creep, thread stripping, or thermal shock fracture. Full-thread precision machining ensures secure engagement with matching C/C nuts and washers.

JUN TENG's Carbon Carbon Washers are precision-engineered companions to our C/C fastener system — designed for 2200°C inert atmospheres and high-purity thermal field applications. With density of 1.63-1.72g/cm³, ash content ≤580ppm, thermal expansion coefficient 0.9-1.4×10⁻⁶/K, and thermal shock resistance exceeding 1200 cycles, they outperform molybdenum and stainless steel washers in weight, purity, and service life. Available in M2-M50 sizes, standard or custom thickness, with optional SiC anti-oxidation coating. Factory-direct, CNC-machined to ±0.02mm tolerance.

JUNTENG's Carbon Carbon Nuts are densely formed in one piece and tightly interlocked with carbon carbon screws. They are resistant to high temperatures of 2000 ℃ without looseness and are resistant to cold and hot impacts, making them less prone to cracking. We have our own factory for direct sales, with sufficient stock and affordable pricing. Suitable for various high-temperature furnaces in photovoltaics and semiconductors, our professional team provides free selection and assembly technical guidance. If you have any purchasing sample needs, please feel free to consult at any time.

JUN TENG's Carbon Carbon Screws are factory-direct high-temperature fasteners manufactured through a three-dimensional weaving and multi-cycle densification process. Designed for smaller diameters (M3-M16) and a wide variety of head types—flat head, countersunk, pan head, and custom geometries—they are ideal for precision fastening in confined spaces, delicate thermal field assemblies, and applications requiring flush mounting. With 2200°C temperature resistance, 70% weight reduction over metal screws, and ash content ≤600ppm, they deliver reliable, contamination-free performance in photovoltaic, semiconductor, and high-temperature industrial environments.
