Tiangong Aihe Awarded "China Good Technology" Honor丨Achieves Major Breakthrough in Domestic Materials with High Hardenability and High Toughness Die-Casting Mold Steel
On November 26, 2025, the "China Good Technology" Conference and the 2024 "China Good Technology" Award Ceremony were held in Beijing. Jiangsu Tiangong Aihe Technology Co., Ltd., a subsidiary of Tiangong International Company Limited, was successfully included in the "China Good Technology" honor list for its original technological achievements and mature industrial capabilities in the field of high hardenability and high toughness die-casting mold steel. Zhang Pengcheng, Deputy Director of the Technology Department at Tiangong Aihe, accepted the "China Good Technology" award on-site and delivered a thematic presentation on behalf of the company, systematically showcasing the technological achievements and application value. This national recognition marks a significant breakthrough for Tiangong in the localization and substitution of high-end mold steel, signifying that the company's core material technology has reached domestically leading and internationally advanced levels.
Original Technological Breakthrough: Key Material Properties Achieve Leapfrog Improvement
Addressing the stringent demands of high-end die-casting molds for materials with high hardenability, high toughness, and high stability, Tiangong Aihe has achieved significant improvements in multiple key indicators through innovative composition system design combined with advanced smelting, remelting, forging, and thermal processing control technologies: Smelting cleanliness has further broken through international bottlenecks, with impurity content significantly reduced; Microstructural uniformity has markedly improved, enhancing material stability and machinability; Core indicators such as impact toughness, hardenability, and thermal fatigue resistance have achieved simultaneous leaps; Comprehensive performance fully aligns with internationally advanced products, stably reaching the level of imported materials.The breakthrough in this technology provides a solid guarantee for the localization of materials in China's high-end die-casting molds, demonstrating outstanding innovative value and significant industrial promotion significance.
Industrial Maturity and Implementation: Established Stable Mass Production Capabilities with Large-Scale Supply Advantages
The project has completed the full-cycle development from design and process validation to engineering application and has successfully passed national standard testing, reflecting a high level of maturity. Tiangong Aihe has established a standardized production line, achieving stable batch production with excellent consistency between batches and reliable performance of key properties. The annual production capacity has reached 2,000 tons, enabling large-scale market supply. Verified by authoritative testing institutions, the product's performance indicators fully meet the quality level of imported similar materials, exhibiting high hardness, high toughness, and excellent microstructural uniformity, positioning it as a leader in the industry.
National Honor Boosts Independent Control of China's High-End Manufacturing Materials
The "China Good Technology" honor is selected by a national authoritative platform, focusing on recognizing outstanding technological achievements with originality, innovation, and breakthrough significance. Tiangong Aihe's award is a high affirmation of the company's long-term commitment to independent innovation, overcoming critical material bottlenecks, and promoting high-quality industry development. This honor not only demonstrates Tiangong's independent R&D capabilities in the high-end mold steel field but also injects strong momentum for the company to enter broader high-end manufacturing application scenarios, accelerate the domestic substitution process, and drive industry technological upgrades.
Looking Ahead: Driving Industrial Upgrading with Innovation, Supporting "Made in China" with Material Strength
Tiangong Aihe stated that the company will continue to uphold the mission of "strengthening the nation through material technology," persist in combining material R&D, process breakthroughs, and industrialization, and continuously introduce more core products with international competitiveness. This will enhance the resilience and strength of the high-end equipment manufacturing industry chain.
In the future, Tiangong will plan technological innovation to higher standards, serve global customers with higher quality, and take on greater responsibility to support China's transition from a "manufacturing powerhouse" to a "manufacturing leader."
