Hydraulic parts with three sealing devices always leak in use, absorber and air spring for example. Hydraulic cylinder can be sealed by itself if friction hot forming technology is adopted on hydraulic cylinder at both ends. By going through the technology, two sealing devices of hydraulic parts are saved, the leak of hydraulic parts is avoided, the rigidity of hydraulic parts is enhanced, the structure of hydraulic parts is optimized and the service life of hydraulic parts is increased.

High strength steel hot forming technology plays an important role in achieving lightweight vehicles, improving the safety of vehicles. The tensile strength of the blank formed by traditional hot forming process is as high as 1500–2000 MPa, the strength of the formed blank is high, but the elongation is usually low and comprehensive mechanical property is not high. In this article, the process control of material gradient properties hot forming technology is summarized through the analysis of strengthening mechanism of gradient distribution hot forming technology. Based on the traditional hot forming technology, a new hot forming technology based on partition cooling to achieve material property gradient distribution is proposed. By changing the cooling rate of blank in different zones is different, and the gradient distribution of material properties is finally obtained. The DEFORM is used to analyze the hot forming process of the blank under the nonuniform temperature field of the partition cooling. A set of partition cooling hot forming die was designed independently to verify the experimental results. The evolution mechanism of microstructure and its effect on material properties during hot forming under nonuniform temperature field with partition cooling were revealed.

A new type of metal composite material can be manufactured by controlling heating temperature and designing the layout of cooling pipes in hot forming process of ultra high strength steel. The yield strength of this type of metal material varies from 380 MPa to 1000 MPa continuously, and its strength limitation varies from 480 MPa to 1600 MPa continuously. In this new hot forming technology, boron steel named as 22MnB5 is stamped by one-step process of hot forming to obtain the metal composite material and manufacture the part consisting of the metal composite at the same time. The hot forming technology of U-shaped part consisting of the metal composite material is provided. Then the microstructure of the U-shaped metal composite material is analyzed and the tensile test is also implemented. The experimental results show the material properties have the characteristics of continuous distribution along the main direction of energy absorption during crash process, which indicates the feasibility of hot forming technology of the metal composite material. The top-hat thin-wall structure consisting of U-shaped metal composite material is employed to analyze the crashworthiness of the new type of metal composite material. By distributing the single phase material of U-shaped composite part properly, the energy absorption ability is increased by 58.7% and the crash force is decreased by 23.4%, which indicate the new type of metal composite material has the comprehensive performance of every single phase material. So the metal composite is a good alternative material in application of crash resistance.
