In today's chemical, power, metallurgical, and municipal engineering sectors, composite materials are playing an increasingly vital role due to their excellent corrosion resistance and high strength. As a leader in the domestic fiberglass and carbon fiber products industry, Mingjin Composite Materials (Lianyungang) Co., Ltd. is showcasing the power of Chinese intelligent manufacturing to the global market. With years of technological accumulation and innovative breakthroughs, the company is steadily advancing toward its goal of becoming a "domestically first-class and internationally renowned" enterprise.

Rooted in Donghai, Radiating Globally

Founded in 2009, Mingjin Composite Materials is located in the North Development Zone of Donghai County, Lianyungang City. The area boasts a highly convenient transportation network: it borders the Changshen Expressway and National Highway 327 to the north, the Coastal Expressway to the east, and the 310 and Lianxu Expressways to the south. This superior geographical location greatly facilitates the introduction of raw materials and the shipment of finished products, enabling Mingjin's products to efficiently serve engineering projects across the country and around the world.

Hardcore Equipment: Overcoming the Challenges of Large-Scale On-Site Winding

In the field of composite material manufacturing, equipment capability often determines the upper limit of product quality. Mingjin Composite Materials understands this well. The company currently possesses FW-4000 microcomputer-controlled horizontal fiberglass winding equipment, various specifications of steel molds for pipes and storage tanks, and FW-25000 on-site fiberglass winding equipment.

What is particularly noteworthy is that Mingjin's on-site winding equipment has overcome a persistent industry pain point. Traditional on-site winding machines can often only perform hoop winding, resulting in insufficient axial strength of storage tanks. However, Mingjin adopts an advanced process combining spiral and hoop winding, enabling the on-site production of giant fiberglass storage tanks with diameters up to 25 meters and volumes up to 5,000 cubic meters. This technological breakthrough not only solves the transportation difficulties of large equipment but also greatly enhances the structural safety of large storage tanks.

In addition, the company recently introduced a continuous winding production line for PP, PE, and PPH plastics, covering continuously wound plastic products with diameters ranging from DN1600 to DN5000. This seamless, one-time molding process significantly improves product quality and production efficiency, further enriching the company's product matrix.

Strict Testing: Guarding the Lifeline of Quality with Data

"Quality is life" is not just a slogan for Mingjin; it is a principle integrated into every stage of production. The company operates a laboratory with comprehensive testing equipment and strong capabilities, recognized as one of the best in China's civilian fiberglass industry.

From microcomputer-controlled electronic universal testing machines and heat deflection/Vicat softening temperature testers to ultrasonic thickness gauges, spark testers, and Barcol hardness testers, the laboratory is equipped with dozens of high-precision instruments. This means that from raw material selection to physical performance testing of finished products, every fiberglass storage tank, tower, pipe, and carbon fiber product leaving the factory has undergone rigorous data verification. The company has successfully passed ISO9001 Quality Management System, ISO14001 Environmental Management System, and ISO45001 Occupational Health and Safety Management System certifications. It has also been awarded the AAAA Credit Enterprise rating, the "Contract-honoring and Promise-keeping Enterprise" title, and the honor of "Advanced Unit in Quality Management" in Jiangsu Province.

Technology-Driven: Building a 24/7 Rapid Response Team

Mingjin Composite Materials understands that excellent products cannot be separated from comprehensive service. The company has established an Engineering Technology Center, featuring a "rapid response team" composed of more than 20 technical personnel with bachelor's degrees or above and intermediate or higher technical titles.

This young and professional team is not only responsible for providing construction guidance to users but also capable of adjusting production processes according to special customer requirements. The company promises:

• Respond to customer service requests within 2 hours;

• Reply to complaints and provide solutions within 24 hours;

• 24/7 hotline service every day of the year;

• During the warranty period, for failures caused by product quality issues, the company will respond within 8 hours and arrive on-site as quickly as possible if technical personnel are needed.

This dual standard of "valuing both product quality and service quality" has earned Mingjin the long-term trust of customers in numerous fields, including chemicals, power, and brewing.

Looking to the Future: Building a Green and Safe Composite Material Intelligent Manufacturing Enterprise

Currently, Mingjin Composite Materials employs a team including postgraduate and doctoral researchers, along with over 80 technical and production personnel. Its annual production of composite materials such as fiberglass and carbon fiber reaches approximately 15,000 tons. Adhering to the business philosophy of "Innovation, Quality, Reputation, and Service," and guided by the corporate culture of "Setting industry benchmarks with technology, guarding the original intention of cooperation with quality," the company continues to forge ahead.

As global requirements for environmental protection and safety continue to rise, Mingjin Composite Materials is actively positioning itself to become a domestically first-class and internationally renowned green and safe composite material intelligent manufacturing enterprise. Whether it is fiberglass storage tanks, towers, pipes, carbon fiber products, or PP/PE/PPH plastic products, Mingjin is committed to providing the most reliable solutions for global customers.
