Compact injection molding method of injection molding part with wire

The present invention provides a compact injection molding method of an injection molding part with a wire, the compact injection molding method comprises the following steps: A, polishing; B, stripping an outer sheath; C, stripping a head, and crimping; D, neutron injection, to be more specific, the wire and a terminal are fixed, the wire and a terminal are firstly closely covered by plastic particles as neutrons; E, two times of injection molding, to be more specific, the wire treated by the step D is divided into two parts, one part comprises the terminal, first, first injection molding of the part comprising the terminal is performed, during the first injection molding, the terminal and the neutron are coated, second injection molding of the other part is performed, during the second injection molding, the wire and the neutron are packed, and the to-be-processed injection molding part with the wire can be formed. By addition of the neutron injection molding before the first injection molding, gaps between the injection molded body and the wire can be effectively eliminated for ensurance of air tightness test to meet corresponding technical requirements, and product quality is improved.
