Eta Prototype Series
Beyond research — EtaSolid delivers prototype systems proven in industrial applications.

The series includes the EcoFoam System, EcoMold System, and Eta One-Cycle Solution, representing advanced technologies in foaming, molding, and AI-based process control.
These systems have demonstrated up to 40% weight reduction, enhanced surface quality (high-gloss, paint-free), and 50% energy savings across automotive, appliance, packaging, and industrial applications.

ETA Solution System
Injection System Based on ETA Solution

EtaSolid’s injection molding machine integrates next-generation supercritical foaming technology (EcoFoam) with advanced mold surface control (EcoMold), forming a unified ETA Solution platform.
Unlike conventional single-plunger systems, it adopts a double-plunger (dual injection unit) structure to achieve precise control and superior foam uniformity.

This configuration allows independent control of injection pressure and gas dosing, maintaining uniform material density while achieving up to 40% weight reduction.
Equipped with an in-house developed AI-based control algorithm and real-time process monitoring sensor network, the system automatically compensates mold temperature, pressure, and gas distribution, minimizing quality deviation during mass production.

The surface achieves Class-A gloss without additional painting, while the internal cell structure maintains high mechanical strength thanks to precisely controlled supercritical nitrogen expansion.
The system supports both structural and non-structural parts for automotive, aerospace, drone, and home appliance industries, and is offered as a complete smart factory package combining EcoFoam-Enabled Injection System, EcoMold Tooling, AI PC Control, and Smart Chiller Integration.

Through this, EtaSolid presents an intelligent lightweight plastic solution that surpasses the limitations of conventional foam injection molding.
