Focus | Industrial Breakthrough and Future Layout of Letone Technology’s Ultra-High-Pressure Equipment Division

When a technology crosses the boundaries of multiple industries and fundamentally reshapes manufacturing processes and performance ceilings of products, it wields the power to reshape entire industrial landscapes. Ultra-high-pressure technology is exactly such an "industrial key". It enables cold sterilization of food while preserving nutrients and flavor without any chemical additives. In addition, its densification treatment delivers a qualitative leap in the energy density and cycle life of solid-state batteries.

As a specialized, sophisticated, distinctive and innovative "little giant" enterprise with over 20 years of intensive cultivation in ultra-high-pressure fluid technology, Letone Technology has maintained clear strategic resolve and solid technical reserves to build an industrial ecosystem for ultra-high-pressure equipment. This ecosystem covers the full technical spectrum of cold isostatic pressing (CIP) and warm isostatic pressing (WIP), all application scenarios including healthy food, new energy and high-end manufacturing, as well as the full product life cycle spanning R&D, pilot testing and mass production. This represents not only the company's strategic upgrade from core component supplier to high-end complete equipment provider, but also a microcosm of China's high-end equipment manufacturing industry achieving self-reliance amid global competition.

Two Decades of Technical Accumulation: The Leap from Components to Complete Equipment

Letone Technology's layout in ultra-high-pressure equipment is by no means a fleeting trend-following move, but an inevitable outcome nurtured by more than two decades of technical accumulation.

Founded in 2003, Letone Technology has focused on the R&D of high-pressure and ultra-high-pressure fluid transmission systems from the very start. It has tackled numerous bottleneck technical challenges in high-end hydraulic hoses, petroleum hoses, resin hoses and other products, which are widely deployed under extreme working conditions such as construction machinery, offshore oil and gas, and nuclear power. These technical accumulations, seemingly unrelated to equipment manufacturing, have actually laid the most solid foundation for the development of complete ultra-high-pressure equipment, given the shared core principles governing ultra-high-pressure fluid control.

In 2024, Letone Technology officially designated ultra-high-pressure equipment as one of the core sectors for corporate strategic development, and continued to build an R&D system featuring "one research institute and four specialized labs". It set up an exclusive Equipment Research Institute and an Ultra-High-Pressure Equipment Application Research Institute, with Professor Yao Jiansong, a senior industry expert, serving as Chief Scientist. This move marks a shift for Letone's ultra-high-pressure equipment division from scattered technical exploration to systematic and large-scale industrial layout.

Parallel Development of Cold and Warm Isostatic Pressing: Building a Full-Scenario Product Matrix

Letone Technology boasts an exceptionally clear technical roadmap for its ultra-high-pressure equipment strategy. The company has pinpointed two core technical directions: Cold Isostatic Pressing (CIP) and Warm Isostatic Pressing (WIP), concentrating resources to achieve leading advantages on its most competitive tracks.

Cold Isostatic Pressing: Mature Technology Targeting Global Large-Capacity Market

Cold isostatic pressing (CIP) technology represents an area where Letone Technology has secured industrial breakthroughs. The technology is now fully mature and available for mass delivery, with its most representative application being HPP ultra-high-pressure sterilization for the beverage industry that retains nutritional value and original flavor.

Letone Technology has developed a full lineup of cold isostatic pressing equipment ranging from 2L lab-scale models to 612L mass-production units, fully covering clients' demands from lab formula verification to large-scale commercial manufacturing. In 2025, the company's 612L series HPP equipment rolled off the production line and entered mass delivery. Certified with the international ASME U3 stamp, Letone has secured a position among the world's top tier of ultra-high-pressure equipment manufacturers.

The cold isostatic pressing equipment market saw explosive growth in 2026, with the first four units of Letone's equipment successfully shipped to customers. Looking ahead, Letone plans to launch a 1000L cold isostatic pressing machine in 2026 featuring world-leading capacity, high efficiency and superior cost performance. The launch of this product will completely break the monopoly held by foreign manufacturers in the large-volume ultra-high-pressure equipment segment and accelerate the popularization of ultra-high-pressure technology across more industrial sectors.

Warm Isostatic Pressing: Targeting All-Solid-State Batteries to Forge the Next Growth Engine

If cold isostatic pressing forms the foundational business of Letone's ultra-high-pressure equipment division, warm isostatic pressing (WIP) serves as the company's future growth driver. Combining moderate temperatures of 90–150°C with ultra-high pressure ranging from 100 to 700 MPa, WIP technology effectively addresses the core pain point plaguing the all-solid-state battery industry: poor solid-solid interfacial contact.

After years of intensive research and development, Letone Technology rolled out its first LTWIP-600-56L lab-scale warm isostatic pressing machine on April 20, 2026, marking the company's mastery of core WIP technologies. In line with its development roadmap, the enterprise will sequentially launch a 159L pilot model and a 312L mass-production unit, while accelerating the R&D of higher-capacity production equipment to fully satisfy the full-cycle demands of all-solid-state battery manufacturers, spanning laboratory research through large-scale commercial manufacturing.

Letone's WIP equipment can reduce the internal porosity of solid-state battery energy storage materials (sulfide, oxide or polymer systems) to below 0.5% and boost green body density by 10%–20%, substantially lifting the energy density and cycle life of batteries.

How Ultra-High-Pressure Technology Reshapes the Future of Industries

Zhao Hongliang, Chairman of Letone Technology, stated in a video: "Ultra-high-pressure technology can trigger structural transformations for numerous products." This statement perfectly encapsulates the industrial value of ultra-high-pressure equipment. Rather than merely optimizing existing production processes, it fundamentally reconstructs manufacturing methodologies and performance thresholds from the underlying logic.

Restructuring the Food Industry: Achieving Health and Great Taste Simultaneously

Within the healthy food sector, HPP cold isostatic pressing technology is spearheading an "additive-free revolution". Unlike traditional high-temperature sterilization, HPP sterilization operates at ambient temperature. It eliminates harmful bacteria while preserving the maximum amount of nutrients and natural flavors in food, with zero preservatives required.

Letone Technology's ultra-high-pressure HPP sterilization equipment is widely adopted for sterilization and fresh-keeping of conventional products such as fruit juices, dairy products, meat and seafood, and its application scope keeps expanding. It enables rapid aging of Baijiu, endowing newly distilled liquor with the mellow taste of aged vintage liquor. It is also applied in the processing of craft beer and ready-to-cook meals, unlocking boundless innovation potential for the food industry.

Empowering New Energy: Breaking the Bottlenecks Restricting Mass Production of Solid-State Batteries

In the new energy sector, warm isostatic pressing (WIP) technology has been universally recognized as an indispensable prerequisite for the mass production of solid-state batteries. Solid-state batteries are regarded as the next-generation power battery solution. Nevertheless, poor solid-solid interfacial contact brings high interfacial impedance and short cycle life, which have long bottlenecked its industrialization.

Letone Technology's LTWIP series warm isostatic pressing equipment delivers uniform 360° all-round pressure and precise temperature control. It optimizes the interfacial bonding between solid electrolytes and electrode materials, drastically cuts interfacial impedance, and improves batch consistency of battery cells.

Outlook: Ultra-High-Pressure Equipment Drives the Enterprise's High-Quality Development

For Letone Technology, the ultra-high-pressure equipment division is far more than a new business growth point; it acts as the core engine fueling the company's strategic transformation and high-quality development. The company has clearly proposed that in the coming years, the ultra-high-pressure equipment business will help the enterprise expand production scale, grow business volume, boost revenue and lift operational efficiency.

To fulfill this target, Letone Technology is speeding up its industrial layout. On April 22, 2026, Henan Letone Precision Manufacturing Co., Ltd. and the Ultra-High-Pressure Equipment Research Institute were officially inaugurated in Zhengzhou, forming an integrated industrial base covering R&D, pilot testing and mass production of ultra-high-pressure equipment. Moving forward, the company will keep increasing R&D investment, rolling out ultra-high-pressure equipment with larger volumes, superior performance and higher intelligence levels, and provide customers with full-lifecycle technical services ranging from process development and customized equipment design to installation, commissioning and personnel training.

From high-pressure hoses for deep-sea oil and gas extraction, to HPP sterilization equipment safeguarding food safety, and warm isostatic pressing machinery powering the new energy revolution, Letone Technology has always upheld its original aspiration and mission: "Make fluid technology bring happiness to hundreds of millions of people".

Amid profound shifts in the global industrial landscape, Letone Technology takes independent innovation as its writing brush and dedication to national industrial development as its ink, composing a brand-new chapter exclusively its own on the grand scroll of China's high-end equipment manufacturing industry.
