is a specialized manufacturer of high-performance ceramic and graphite products. Our core business portfolio encompasses thermal field consumables for lithium batteries, supporting components for PV and energy storage systems, industrial electronic ceramic components, and precision grinding media. We deliver mission-critical solutions that enable high-temperature sintering,

graphitization, powder processing, and power transmission applications across the new energy, electronics, and advanced manufacturing sectors.

Within the lithium battery segment, we focus on supporting the high-temperature sintering of cathode materials and graphitization of anode materials, providing highly reliable kiln furniture solutions for the global new energy battery industry.

Our core product portfolio for battery material manufacturing comprises two primary sagger series:

• Corundum-mullite and cordierite-mullite saggers (mullite cordierite saggers), with an annual production capacity of 4 million units
• Graphite saggers, with an annual production capacity of 600,000 units

We engineer application-specific saggers optimized for a broad spectrum of battery material chemistries, including ternary cathode materials (NCM/NCA), sodium-ion battery materials, lithium cobalt oxide (LCO), lithium manganate (LMO), and lithium iron phosphate (LFP). These products serve as essential consumable kiln furniture throughout the cathode sintering and anode graphitization processes.

Leveraging our proprietary compression molding technology, our graphite saggers exhibit exceptional flexural and compressive strength. Compared with conventional assembled or solid-machined graphite saggers, our solutions deliver superior performance in production throughput, cost efficiency, manufacturing yield, and quality consistency, earning widespread industry recognition.

We maintain close strategic partnerships with leading enterprises across the lithium battery value chain, covering top-tier cathode material manufacturers and power battery giants. 70% of our sales revenue is derived from industry-leading customers.

Our core partners include CTAL, BYD, BASF Shanshan, Wanhua Chemical, and Huayou Cobalt. In 2023, we were awarded the "Best Quality Supplier" title by Huayou Cobalt, a formal testament to our consistent product quality and robust supply reliability.

Our production facilities cover a total area of 68,000 square meters, with a workforce of over 300 employees. The company has sustained annual revenue exceeding RMB 250 million for three consecutive years.
