Two reinvestment projects, focusing on intelligent key basic components and new materials for deep-sea aquaculture, were signed at the Gangzha Economic Development Zone in Chongchuan district on March 24. 

The intelligent key basic components R&D and manufacturing project by Zhengtian Heavy Industry has a total investment of 550 million yuan ($79.59 million) and is being funded by Jiangsu Zhengtian Heavy Industry. This project will add high-end equipment to enhance the intelligence level of production lines, create an industry-leading production system and achieve independent supply of core components. 

The Xindi Synthetic Monofilament R&D and manufacturing project for new deep-sea aquaculture materials involves an investment of approximately 1.12 billion yuan, led by Nantong Xindi Synthetic Monofilament Technology. This project aims to focus on the modification of polymers, the spinning of ultra-large diameter polymer monofilaments, and R&D and production of hexagonal nets specifically designed for deep-sea aquaculture applications. 

Both companies have been rooted in Chongchuan for more than 20 years, having grown from startups to industry benchmarks. This reinvestment demonstrates their recognition of Chongchuan's business environment and their confidence in its development.
