In October 2026, the company's Shanghai headquarters and Jiangsu production base successively completed ISO9001:2015 quality system certification, marking the sixth consecutive annual pass and confirming that product production, raw material procurement, sales service, testing, and quality control remain in a well-controlled state. The company aims to use this quality review as an opportunity to continuously improve product quality and customer service, delivering sustained high-quality service to industry customers and achieving long-term mutual benefit. In the third quarter, the company's calcined-grade fine-cast zircon sand and zircon powder products obtained product testing and production certifications from high-end precision casting enterprises and received contract orders, marking the success of new product development over the past two years. Made from high-quality Australian zircon sand through special high-temperature calcination above 1300°C and prolonged heat preservation, the products feature more stable physical and chemical properties at high temperatures, better refractoriness, and an extremely low thermal expansion coefficient. Fine-cast coatings prepared with this powder can significantly enhance permeability, reduce sand adhesion defects, and improve the surface finish of investment casting parts. Its particle size distribution meets aviation engine system quality requirements, making it suitable for import substitution and enabling the company to provide high-quality raw and auxiliary materials to high-end precision casting enterprises.

           In October 2026, the company's Shanghai headquarters and Jiangsu production base successively completed ISO9001:2015 quality system certification. This marks the sixth time the company has passed the review annually, indicating that the company continues to maintain a good and controllable state in product production, raw material procurement, sales service, testing, and quality control. The company hopes to leverage the opportunity of quality review to continuously optimize product quality and customer service through sustained improvement, providing continuous high-quality services to industry customers and achieving long-term mutual benefit and win-win results.

 In the third quarter, the company's calcined-grade fine-cast zircon sand and zircon powder products successively obtained product testing and production certifications from high-end precision casting enterprises in the industry, and also received contract orders, marking the success of the company's new product development over the past two years. The calcined-grade fine-cast zircon sand powder is made from high-quality zircon sand imported from Australia. Through special high-temperature calcination at over 1300 degrees and long-term heat preservation, its physical and chemical properties become more stable at high temperatures, with better refractoriness and an extremely low thermal expansion coefficient. The fine-cast coating prepared with calcined-grade fine-cast zircon powder can significantly enhance the permeability of the coating, reduce the occurrence of sand adhesion defects, and improve the surface finish of investment casting parts. The particle size distribution of calcined-grade fine-cast powder meets the quality requirements of the aviation engine system, making it suitable for import substitution of similar products and providing high-quality raw and auxiliary material services to high-end precision casting enterprises.
