In today’s rapidly evolving plastic industry, automation has become indispensable for optimizing processes and maximizing efficiency. In-Mold Labeling (IML) robots represent a pinnacle of innovation within the injection molding process, offering unparalleled precision, speed, and versatility. In-Mold Labeling Robots (IML Robots) are cutting-edge industrial automation solutions designed to streamline the process of labeling molded products directly within the mold cavity during the injection molding process. This innovative technology offers several advantages over traditional post-molding labeling methods, including increased efficiency, improved product quality, and enhanced flexibility.
IML robots are equipped with advanced robotic arms, precision vision systems, and sophisticated control systems, allowing them to handle and place labels with utmost accuracy and consistency. The process involves inserting pre-printed labels or films into the mold cavity before injecting molten plastic, thereby seamlessly integrating labeling into the molding cycle. Unlike traditional post-molding labeling methods, IML robots insert labels directly into the mold cavity before injection, resulting in a fully automated labeling process. With the use of sophisticated technologies like robotic arms, vision systems, and programmable logic controllers (PLCs), these robots are able to precisely insert labels and coordinate with injection molding equipment.

How In-Mold Labeling Technology Works
For manufacturers optimizing their production lines, understanding the workings of in-mold labeling robots is crucial. The process is a perfectly sequenced integration of cutting-edge robotics and intelligent automation.
When an injection molding machine triggers the robotic system, the system begins its labeling cycle. The robotic vision system analyzes the mold cavity and identifies pre-defined alignment and marker points. The robotic arm receives this instant visual feedback as part of the closed-loop system and determines the path for label placement. The label, which may be a pre-printed film, foil, or specialty material, is positioned and inserted into the mold cavity just before the injection of molten plastic.
Delta Stark’s IML robotic solutions are particularly effective due to their perfectly sequenced and timed integration with injection molding equipment. Our robotic systems are designed to perform cycle times of manual labeling while exceeding expected accuracy and consistency.
Whether you’re utilizing our top-entry IML labeling system or our side-entry IML solution, both configurations are engineered to maximize production throughput without compromising label quality.
The integration of intelligent PLCs ensures that every movement is optimized, reducing idle time and waste. This level of automation sophistication transforms the manufacturing process, turning what was once a labor-intensive, error-prone operation into a streamlined, predictable workflow.
Key Components and Features of In-Mold Labeling Robots:
- Advanced vision systems utilize cameras and sensors to detect mold features and guide the robotic arm with pinpoint accuracy during label placement.
- PLCs serve as the control center, orchestrating the movements and operations of IML robots in synchronization with injection molding machines.
