Major Collaboration | Changtong Electronics has formed a strategic partnership with a global semiconductor giant to usher in a new era of precision cutting for optical communications.

From May 13 to 15,2026, U.S. President Donald Trump embarked on a state visit to China. Among the delegation of representatives from 16 leading global companies, six semiconductor industry leaders attracted significant attention. Currently, the global AI sector is experiencing explosive growth with continuously rising demand for computing power, and optical communications, as a core component of AI infrastructure, are facing unprecedented development opportunities. Against this backdrop, Yutian Changtong Electronics Co., Ltd. (hereinafter referred to as "Changtong Electronics"), leveraging its 28 years of technical expertise in precision cutting, established a long-term strategic partnership with one of Coherent's semiconductor subsidiaries, becoming its primary supplier of cutting equipment for optical communication core materials and jointly driving a revolutionary upgrade in optical communication manufacturing processes.
As a national technology enterprise, Changtong Electronics specializes in the research, development, production, and innovation of multi-line cutting machines, possessing multiple core patents and maintaining a leading position in technical capabilities within the industry. Through this collaboration, both parties addressed key challenges in precision cutting of optical communication materials and jointly overcame technical hurdles, achieving a significant breakthrough by replacing traditional mortar-based cutting with diamond wire cutting. This advancement completely eliminates the industry bottleneck that limited optical communication materials to mortar machine processing, delivering cutting quality on par with or even superior to that achieved with mortar machines through diamond wire cutting technology, thereby providing essential equipment support for cost reduction, efficiency improvement, and quality enhancement across the industry.
Technological Innovation: A Leap in Performance The jointly developed multi-wire cutting machine and its accompanying cutting equipment have achieved comprehensive, transformative improvements in core performance: • Production Capacity Enhancement: Compared to traditional mortar machines, overall production capacity has increased nearly fivefold, significantly overcoming bottlenecks in processing optical communication materials; • Cutting Efficiency: Cutting speed has been boosted by 1.25 times, effectively meeting the demands of large-scale production for optical communication products in the AI era; • Precision Optimization: Tool edge wear has been reduced by 25%–50%, material yield rate improved by 20%, material waste minimized, and production costs substantially lowered; • Comprehensive Supporting Systems: A dedicated multi-wire cutting machine was co-developed to enable one-step cutting and precise positioning in upstream processes, delivering a full-process precision manufacturing solution for "cutting – slicing" that enables efficient workflow coordination for customers.
With deep expertise and remarkable achievements, Changtong Electronics has consistently advanced in the field of precision cutting for optical communications, leveraging its leading technological capabilities and reliable product quality. The company has established stable partnerships with numerous industry leaders, with its products widely used in cutting core materials such as optical communication chips and optical components. Recognized for their high stability, precision, and cost-effectiveness, these solutions have earned widespread market acclaim.
This strategic collaboration with a global semiconductor giant marks a significant milestone in Changtong Electronics 'international expansion and serves as a direct testament to the company's technological prowess and product competitiveness. Moving forward, Changtong Electronics will steadfastly uphold its development philosophy of "technological innovation, quality as the foundation, and win-win cooperation," deepen expertise in precision cutting core technologies, continuously overcome industry technical barriers, and empower the high-quality development of the global optical communications and semiconductor industries through superior products and services. We are committed to advancing alongside partners amid the wave of AI development and jointly creating new achievements for the industry!
