About Haifeng
Zhejiang Haifeng Automation Equipment Co., Ltd., operating globally as Haifeng Polyurethane Machinery, is a polyurethane equipment manufacturer and turnkey production-line supplier based in Wenzhou, Zhejiang, China.
Our technical roots date back to Wenzhou Dongfeng Plastic Machinery Factory, founded in 1986. Haifeng began specializing in polyurethane processing equipment in 1995, and the current corporate entity was established in 2001. This engineering heritage supports our long-term mission: making polyurethane production more measurable, controllable, and repeatable.
Haifeng designs and manufactures low-pressure polyurethane dispensing machines, high-pressure foaming machines, polyurethane elastomer casting machines, spraying systems, supercritical foaming equipment, continuous foam lines, sandwich panel lines, and customized polyurethane automation systems. Our solutions serve automotive, footwear, synthetic leather, furniture, tires, railway infrastructure, thermal insulation, industrial elastomers, and composite manufacturing.
Each project is engineered around the customer’s raw materials, viscosity, mixing ratio, output range, temperature requirements, production cycle, product structure, and automation objectives. Our services cover process consultation, equipment engineering, manufacturing, installation, commissioning, operator training, and lifecycle technical support.
Haifeng operates a 15,076 m² headquarters manufacturing base and has three additional manufacturing bases operated by its affiliated companies. Our broader engineering and service network comprises approximately 120 people, including more than 50 technical professionals. These figures include personnel at our technical service locations as well as external specialists in polyurethane equipment, processing technologies, and industrial applications.
With equipment and engineering experience serving more than 1,200 customers worldwide, Haifeng provides standalone polyurethane machines, customized production cells, and complete turnkey production lines.
