UN Series Injection Molding Machine (1350T–6000T)

SOUND Machinery’s UN Series (1350T–6000T) Injection Molding Machines represent the cutting edge in large-scale, high-efficiency plastic molding technology. These machines are built for industrial giants—automotive parts, waste bins, logistics containers, and more—requiring massive clamping force and ultimate repeatability.
Designed with precision mechanics and reinforced clamping structures, the UN Series ensures mold longevity and reduced deformation. The injection units are equipped with high-speed servo systems, closed-loop SSR barrel control, and custom screw options for different materials. This allows for superior melt homogeneity and shot weight accuracy between 0.3% and 0.7%.
Additionally, the machines feature advanced hydraulic circuitry with minimal energy loss, quick response, and automated safety diagnostics. The large-screen UI and MES-ready control system make this series a perfect fit for smart factories.
With a legacy dating back to 1955, SOUND MACHINERY continues to lead as a top-tier injection molding machine manufacturer. The UN Series is a direct response to the global demand for heavy-duty machines that don’t compromise on efficiency or intelligence. Join manufacturers across 60+ countries who trust SOUND for long-term performance and technological excellence.
