The 4-cavity Type‑C TPE outer film mold is a precision injection mold designed specifically for producing soft protective overmolding on Type‑C connectors. It is typically used to manufacture the outer TPE (thermoplastic elastomer) jacket or film that surrounds metal shells or inner plastic parts, providing strain relief, insulation, and enhanced durability.This mold features four cavities arranged to optimize both cycle time and material flow balance. By running four parts per shot, production efficiency is significantly improved while maintaining consistent dimensional accuracy across all cavities. The runner and gate system is engineered to ensure uniform filling of each cavity, reduce pressure loss, and minimize weld lines and air traps, which is especially important for thin‑wall TPE film structures.TPE material has particular flow and shrinkage characteristics, so the mold design pays special attention to venting, parting line precision, and cooling layout. Proper venting helps avoid burn marks and short shots, while an optimized cooling channel system stabilizes the molding temperature and shortens cycle times. The mold base and cavity inserts are typically made of high‑quality tool steel with surface treatments to resist wear and corrosion under repeated TPE processing.The cavity geometry conforms closely to the outer surface of the Type‑C connector design, forming a uniform soft film layer that offers comfortable hand feel and secure grip during insertion and removal. Critical dimensions, such as the interface area near the metal shell and cable exit, are tightly controlled to ensure reliable assembly with downstream components and to maintain durability in repeated bending and plugging cycles.Interchangeable inserts can be used to adapt the mold to different cable diameters, color variations, or minor design updates without replacing the entire mold. This modular approach reduces maintenance costs and allows flexible production for different product variants. Ejector pins, stripper plates, or a combination system are configured to ensure smooth demolding of the soft TPE parts without deformation or surface damage.The mold is usually compatible with standard injection molding machines and can be integrated into automated production cells, including automatic loading of metal housings or inner cores for overmolding. With robust alignment features, precise guiding components, and reliable cooling and hot‑runner (or cold‑runner) options, the 4‑cavity Type‑C TPE outer film mold offers stable mass production capability, high yield, and consistent product quality for modern Type‑C cable and connector applications.
