The iMulti-S is a digital hydraulic valve gate controller designed for sequential injection molding applications in hot runner systems. It provides precise digital control of hydraulic valve gate actuation, enabling sequential filling of multi-cavity or large-area injection molds. The digital control architecture allows for programmable gate opening and closing timing, improving knit-line placement and reducing part warpage in complex molded components.

Why use digital valve gate control over mechanical sequencing?

Digital control allows operators to program and adjust valve gate opening/closing sequences from the HMI without mechanically re-timing cams or limit switches. This enables rapid mold changeover and fine-tuning of fill patterns to optimize part quality — particularly important for family molds and multi-gated large parts where knit-line position is a critical quality parameter.
