We are China's first high-tech company to develop fully automatic manufacturing equipment for type IV composite pressure vessels, which can be applied to manufacture composite vessels such as LPG cylinders, hydrogen storage vessels, CNG cylinders, etc. The Automatic production line includes liner blow molding, fiber winding, curing, cylinder testing, and other special equipment.

We focus on the research of composite pressure vessels made of nonmetallic fibers, fully wound composite material systems, molding processes, and intelligent manufacturing equipment. Successfully developed a type Ⅳ composite cylinder automatic flexible production line, and became the second company in the world that can independently research and develop new composite vessels, intelligent production equipment, and provide composite pressure vessels with independent intellectual property rights for the entire industry chain solution.

As gas is becoming a more popular energy source, the demand for the storage and transport of gas is also increasing. One way of storing and transporting the gassings of composite cylinders, which can meet the requirements for safe and cost-effective transport under high pressure. To achieve high output production of the composite cylinders. WUXI LONGTERM offers automated production lines for LPG, CNG, hydrogen, and other types of high-pressure vessels. Depending on the required yearly capacity output and dimensions of the cylinders, we can design automated production lines starting from 30,000 pieces and up to 1,000,000 pieces per year.
