In order to improve the mechanical properties and wear resistance of ultra-high molecular weight polyethylene (UHMWPE) hollow parts, a self-developed hollow part forming mold was used, and pulse vibration was introduced during the compression molding process, so that the material can be formed under pulse pressure. The effect of impulsive vibration on the microstructure and macroscopic properties of the part was studied. Through tensile test, mortar abrasion test, DSC test, density test and 2D-WAXD test, the results show that the application of pulse vibration can increase the density, orientation and crystallinity of the sample, and its tensile properties and wear resistance are better than those molded under static conditions.
