Description

technical field [0001] The invention relates to a material micro-molding forming device and method, in particular to a high-frequency vibration-assisted micro-molding forming device and method. Background technique [0002] With the rapid development of micro-electromechanical systems and micro-mechanisms, the demand for micro-components continues to increase, and the requirements for micro-forming quality are also increasing, requiring high geometric dimension accuracy and shape and position accuracy. Plastic micro-forming has obvious advantages in terms of processing efficiency, material utilization, manufacturing cost, part performance and dimensional accuracy. However, affected by the friction size effect, the friction force on the component during the micro-molding process increases significantly as the size decreases. , there is often the problem of incomplete filling of microstructures and limited size of forming features, which limits the wide application of micromol...
