The Double L-Ring Drum Blow Molding Machine is a patented, intelligent, eco-friendly and high-speed machine designed for producing double-layer 220L products, with a maximum production speed of 70 seconds per piece. It is a patented, intelligent, energy-saving and high-output machine.
The YY-220fast-2 hollow blow molding machine can manufacture various double L-ring drums, chemical drums, as well as other barrels, bottles and containers made of polyethylene, polyvinyl chloride, styrene polymers and other materials. These products are widely used for holding chemical raw materials, chemical liquids, food, chemicals, pharmaceuticals, daily necessities and other applications.
Since many manufacturers have a limited production workforce, the degree of automation of equipment has become a key factor that single L-ring drum manufacturers must take into account. The fully automatic single L-ring drum blow molding production line can not only reduce the labor intensity of on-site operators, but also significantly improve the production efficiency and quality of single L-ring drums.

Recently, Weifang Yuyang Plastic Machinery Co., Ltd., a national high-tech enterprise, officially launched the world's first double-station blow molding machine. This new machine integrates intelligence, high efficiency, environmental protection and energy saving. It breaks the limits of traditional single-station blow molding machines and rebuilds the production mode of hollow plastic products. It brings new energy to the global plastic processing industry and shows that China's blow molding technology has reached the world's top level.
Our professional technical engineers accompanied the visit throughout. Combined with the customer’s actual production conditions and process requirements, we delivered full-process operation demonstrations, precise parameter debugging and long-duration continuous operation tests. The equipment delivered stable single-station operation, smooth ring drum circulation and reliable automated control logic, fully demonstrating its superior overall performance. The customer closely inspected the mechanical structure, operational efficiency and production compatibility. They spoke highly of the equipment’s stable performance, optimized process design and reliable manufacturing quality. This successful on-site trial run further strengthens mutual trust and lays a solid foundation for future in-depth cooperation and seamless product delivery.
Many new customers were attracted by the company’s new product technology, complete solutions and the professional ability of the technical team. They took the initiative to communicate with staff about product details, customized needs and cooperation ways. Many old long-term partners also came to the booth on purpose. They showed their recognition and trust in the quality of Yuyang’s products. One old customer said, "We have cooperated with Yuyang Plastic Machinery for many years. Its equipment runs stably with low energy consumption, and after-sales service responds quickly. It not only helps us cut production costs, but also improves production efficiency. We come here specially to deepen our cooperation and develop more market chances together."
In the future, Yuyang Plastic Machinery will keep focusing on the plastic machinery industry, pay attention to technical innovation and quality improvement, constantly raise product technology and customized service ability, improve international service system, and steadily expand overseas markets. Yuyang will work together with more overseas customers, build a high-end international brand with professional ingenuity, and support the high-quality development of the global plastic and rubber industry.
