Abstract: The forming process of the shape and structure of a certain electrical adjustment seat component was analyzed, and Moldflow software simulation results was used to guide the improvement and optimization of the gate type and position in the design scheme of the metal injection molding mold. Finally, the design of the metal injection molding mold is completed. Through actual production verification, the mold structure is reasonable, and the product quality of injection molding using this mold meets customer′s requirements.
