At Fakuma 2026, ELMET will present its SMARTshot i system for the first time. This new generation of intelligent cold runner technology for LSR injection molding continuously analyzes the injection process, automatically balances the cavities, and independently optimizes the nozzle pin positions.

ELMET’s SMARTshot i system.

When used with family molds featuring cavities of varying sizes, SMARTshot i automatically adjusts the nozzle positions to match the specific filling behavior of each cavity.

In tests with a 16-cavity mold, only 20 shots were needed to perfectly balance the cold runner. This reduced the ramp-up time by up to 95% compared to the conventional approach.

High-precision servo-electric needle control

As part of the optimization process, SMARTshot i uses the high-resolution data collected during injection to analyze and control the process. Pressure sensors in the cavities are not required.

Thermal changes during the ramp-up phase are also detected and compensated for by continuously adjusting the needle positions. The system’s ability to position each nozzle needle servo-electrically with an accuracy of 2 µm is a key factor in its high balancing speed.

SMARTshot i is designed to be AI-ready and serves as the technological foundation for further automation steps. Currently under development are features such as online rheometry for real-time measurement of material viscosity and material fluctuation detection without external sensors.

Experience SMARTshot i live and digitally at Fakuma 2026

Visitors to Fakuma 2026 can explore SMARTshot i from two perspectives. A live demonstration at the Momentive Performance Materials booth will showcase the technology in a real-world production process.

Additionally, a digital twin of the SMARTshot i at ELMET’s booth will provide an in-depth look at the technology and development work behind the system. It reveals functions and interrelationships that are usually hidden during the injection molding process.
