Product details

This injection mold is designed for precision electrical connector components used inside electrical and electronic products. Although these parts are compact in size, the mold itself presents a number of demanding technical challenges due to the high functional requirements of electrical assemblies. The primary challenges lies in the high-density cavity layout combined with extremely fine functional details. The connector components feature multiple small positioning structures, pin alignment areas, and internal support features that must be formed accurately in every cavity. Any dimensional deviation, even at micron level, may result in poor contact alignment, assembly difficulty, or unstable electrical performance. And the major difficulty is strict dimensional consistency across all cavities. Electrical connectors rely on precise positioning to ensure correct mating with metal terminals or pins. The mold must maintain uniform cavity dimensions, consistent shrinkage behavior, and excellent steel stability throughout long production cycles. This places very high demands on mold base rigidity, insert design, and machining precision.

The gate and runner system design is also highly challenging. Due to the small part volume and thin-wall areas, melt flow must be carefully balanced to avoid short shots, jetting, or uneven filling. At the same time, gate marks must be minimized to prevent interference with functional or assembly surfaces. Achieving stable filling across multiple cavities requires extensive simulation, validation, and fine-tuning during mold trials. Electrical connector parts are often molded from engineering plastics with specific electrical insulation, heat resistance, and mechanical strength requirements. Each material presents unique flow and shrinkage characteristics, which must be fully considered during mold design and steel selection to guarantee long-term production stability. The mold base steel is S50C and mold insert steel uses S136 steel with a hardness of HRC48 - 52, and the mold life of the steel can reach 500,000shots or more. Our company is very experienced in Connecter Plastic Mould, Elbow injection mold, PVC Injection Mould.
