We offer products and technical support to different industries, such as injection moulding machineries, forging machineries, food machineries, hydraulic cylinders, mining and construction machineries, logistic and port machineries and marine machineries etc. Based on our experience and customers' requirements, we have been researched and developed a series of tools for seal solution since 2006 also known as SEALTOOL, which solved many problems that could not be done in the past.
