Over 20 Years of Breakthroughs in Ultra-High Pressure Technology: Letone Technology's Domestic Isostatic Pressing Equipment Paves a New Path for Solid-State Battery Industrialization

As solid-state batteries emerge as the next technological high ground in the global new energy industry, the sector has long been hampered by a common challenge: poor solid-solid interface contact, high internal porosity of battery cells and insufficient density of electrode materials. These issues lead to high interfacial resistance, short cycle life and poor batch stability, forming an invisible barrier between laboratory technologies and large-scale mass production.

As a specialized, sophisticated, distinctive and innovative "Little Giant" enterprise with over 20 years of expertise in ultra-high pressure fluid technology, Letone Technology has independently developed the LTWIP series warm isostatic pressing equipment through years of technological accumulation and continuous innovation. It delivers a reliable domestic solution for solid-solid interface densification of solid-state batteries and advances the localization of high-end equipment.

Steady Progress: A Down-to-Earth Journey of Technological Breakthroughs

Letone Technology's breakthroughs in warm isostatic pressing are no accidental cross-industry attempt, but an inevitable achievement stemming from more than two decades of dedicated research. In earlier years, the company overcame multiple core bottleneck technologies in high-end hydraulic components and ultra-high pressure HPP food sterilization, building up full-industry-chain experience covering ultra-high pressure system design, precision component manufacturing and complete equipment assembly and commissioning. These seemingly unrelated technological reserves have laid a solid foundation for the R&D of warm isostatic pressing equipment. The core principles of ultra-high pressure fluid control are consistent across fields, and the rigorous optimization of product reliability and safety over the years has become the core competitiveness of Letone Technology's products.

After years of dedicated research, the first LTWIP-600-56L warm isostatic pressing equipment of Letone Technology officially rolled off the production line on April 20, 2026. Just two days later, Henan Letone Precision Manufacturing Co., Ltd. and the Ultra-High Pressure Equipment Research Institute were inaugurated and put into operation in Zhengzhou. This move is more than a mere expansion of production capacity; it represents an integrated industrial base combining R&D, pilot testing and mass production built by Letone for the ultra-high pressure equipment sector. It marks that Letone's layout in this field has evolved from individual technological breakthroughs to systematic and large-scale development.

Solid Support: Building an R&D System with In-depth Integration of Industry, Academia, Research and Application

Sustained technological iteration relies on a sound R&D platform and professional talent team. Regarded as the lifeblood of the enterprise, technological innovation has always been a top priority for Letone Technology, which has established a complete and efficient R&D system. Supported by its R&D framework of one institute and four divisions, Letone has pooled talents from various fields and formed an interdisciplinary collaborative research model. Professor Yao Jiansong, a senior industry expert, serves as the chief scientist of the Ultra-High Pressure Equipment Research Institute. His team not only optimizes the performance of existing equipment, but also takes the lead in researching next-generation warm isostatic pressing technologies, accumulating technological reserves for the company's long-term development.

Meanwhile, Letone Technology has built standardized R&D laboratories and intelligent production workshops equipped with world-class testing and processing facilities. A full-process quality control system has been established covering independent R&D of core hydraulic components, every production procedure of equipment assembly and rigorous pre-delivery testing, ensuring stable and reliable operation of all delivered equipment.

Full-cycle Product Portfolio: Precisely Catering to Diverse Enterprise Needs

Solid-state battery enterprises of different scales and development stages have vastly varying demands for production equipment. Fully aware of this, Letone Technology has developed a product portfolio spanning the entire lifecycle from R&D and pilot testing to mass production, delivering solutions tailored to clients' practical requirements.

The experimental model LTWIP-600-56L is specially designed for laboratory research and small-scale trial verification. Featuring compact size and flexible operation, it enables researchers to quickly test the performance of different material formulas and process parameters, greatly shortening the R&D cycle and cutting early trial-and-error costs, thus helping enterprises avoid detours during technological exploration.

The pilot-scale model LTWIP-600-169L serves as an ideal link between R&D and mass production. It ensures smooth transition of process parameters, and allows enterprises to fully verify the feasibility and stability of production processes before formal large-scale manufacturing. Potential problems can be identified and resolved in advance to accelerate commercialization and seize market opportunities.

Going forward, Letone Technology will launch the mass-production model LTWIP-600-326L and other models with larger volumes, to fully meet the high-volume production demands of enterprises of all sizes.

The full-system equipment boasts six major advantages: 360° omnidirectional uniform pressurization, precise temperature control over a wide range, high efficiency and cost reduction, one-piece forming for complex structures, fully automatic intelligent control, as well as environmental friendliness and strong compatibility with multiple application scenarios. It addresses industry pain points with quantifiable indicators and provides solid equipment support for the large-scale development of the solid-state battery industry.

Beyond supplying a full range of warm isostatic pressing equipment, Letone Technology has built a one-stop full-lifecycle technical service system covering process development, customized equipment design, on-site installation and commissioning, personnel training and after-sales maintenance. Moving forward, adhering to the development philosophy of "Leading through innovation, Creating value for all", Letone Technology will work hand in hand with all partners to drive the high-quality development of China's new energy and high-end manufacturing industries.
