Good News | Yutian County Changtong Electronics has once again successfully obtained the certification as a National High-Tech Enterprise.

Recently, following a joint evaluation by the Ministry of Science and Technology, the Ministry of Finance, and the State Taxation Administration, Yutian Changtong Electronics Co., Ltd. has once again successfully obtained national high-tech enterprise certification, leveraging its profound technical expertise, sustained independent innovation capabilities, mature manufacturing processes, and industry-leading equipment R&D capabilities, thereby maintaining its status as a nationally recognized high-tech enterprise.
This successful re-certification represents high recognition from national authorities regarding our company's R&D capabilities, innovative achievements, core technological expertise, and comprehensive innovation capacity. It also stands as the ultimate testament to our enterprise's three-decade commitment to advancing cutting, grinding, and polishing technologies for hard and brittle materials through continuous technological iteration and innovation.
With over three decades of dedicated industry expertise, our company has built robust technical capabilities in the fields of piezoelectric crystals and cutting, grinding, and polishing of hard and brittle materials. Established in 1998, we have specialized in these areas for nearly three decades. As early as 2001, we were recognized as a High-Tech Enterprise in Hebei Province; in 2016, we successfully upgraded to National High-Tech Enterprise status and have since consistently passed re-evaluations, maintaining a leading position in technological innovation within the industry.
The company boasts a unique dual industrial advantage in the industry: it is both a manufacturer of precision processing equipment for hard and brittle materials and a leading R&D and production provider of multi-line cutting machines. Leveraging years of practical experience in crystal processing, our company has achieved industry-leading breakthroughs in the edge guiding, slicing, and precision grinding/polishing processes for piezoelectric crystals at the 49S frequency band. Our process maturity, yield rate, and stability rank among the highest domestically, establishing us as a benchmark in processing technology.
With sixteen years of dedicated self-developed and self-produced equipment development, we have established industry-leading standards. Driven by our own manufacturing needs, our company officially initiated the independent research, development, and production of multi-line cutting machines for internal use in 2008, and launched full-scale market sales in 2010. To date, we possess extensive experience spanning sixteen years in complete machine R&D, assembly, and iterative refinement. Starting from traditional mortar machines, we have continuously pursued technological innovation, cultivating multiple groundbreaking competitive advantages in the industry.

1. Completely air-compressor-free design for optimal energy efficiency and reduced consumption: All our multi-line cutting machines require no additional air compressors, eliminating the common drawbacks of traditional equipment such as high energy consumption, excessive noise, and frequent malfunctions. Each unit can save nearly ¥100,000 in annual electricity costs, significantly lowering production expenses and enhancing operational efficiency for customers.

2. Ultra-high cutting line speed: The production efficiency leads the industry, with a stable line speed exceeding 2,200 m/s; under mass production conditions, it can consistently maintain a high line speed above 1,600 m/s, delivering cutting efficiency and output capacity that far surpass those of conventional industry equipment.

3. Extensive processing range: Compatible with mass-production equipment across multiple material categories, offering a wide thickness coverage from 0.3 mm thin sheets to 60 mm thick materials with stable roller winding cutting performance. Suitable for various hard and brittle materials including piezoelectric crystals, ceramics, quartz, sapphire, and magnetic materials, featuring comprehensive applicability and exceptional versatility.
Adhering to independent R&D, Changtong Electronics has leveraged multiple core patents to drive industry advancement. Over the years, the company has consistently prioritized technological innovation as its core strategy, significantly increasing R&D investment and focusing on optimizing equipment architecture, upgrading manufacturing processes, and advancing intelligent technologies. Its independently developed core technologies—including dual-station multi-line cutting machines, rotary tool holder-based multi-line cutting machines, and single-line independent function capabilities for multi-line cutting systems—all enjoy proprietary intellectual property rights.
Multiple original technologies have filled gaps in specialized industry segments, effectively addressing key challenges such as poor cutting accuracy, high wire breakage rates, high energy consumption, and limited versatility, thereby continuously driving high-quality development in the hard-brittle material cutting sector.
Changtong goes beyond merely supplying equipment; it offers comprehensive end-to-end manufacturing solutions. What sets it apart from conventional equipment manufacturers is its profound expertise in processing, production techniques, and mass production capabilities.
We not only provide customers with high-performance multi-line cutting equipment characterized by exceptional stability, low energy consumption, and high efficiency, but also offer comprehensive solutions—including mature cutting processes, mass production plans, debugging techniques, and on-site production guidance—for both new and existing clients. These services genuinely enable customers to accelerate production launch, achieve stable mass output, reduce waste, and improve product yield rates.
Being recognized as a National High-Tech Enterprise once again is both an honor and a responsibility. Moving forward, Changtong Electronics will remain committed to its innovation ethos, continue advancing research and development in precision machining technologies and intelligent cutting equipment, and empower the global hard and brittle materials processing industry with superior products, mature manufacturing processes, and comprehensive technical services.
