Integrate IML labels, injection molds, molding machines and robots into one automated production solution for plastic containers.
IML packaging combines plastic injection molding and in-mold labeling in a single production process. A preprinted label is placed inside the injection mold before molding, allowing the label to become integrated with the plastic container during the injection molding cycle.
For automated IML packaging production, the label, injection mold, injection molding machine and IML robot must work together as a coordinated system. The robot handles label picking and placement and can also remove the finished molded containers after injection molding.
HecosTech provides customized IML automation solutions for plastic packaging applications. Robot configuration, EOAT, label handling, mold layout and downstream processes can be evaluated according to the container, injection molding machine and required production sequence.
What Is IML Packaging?
IML packaging, or in-mold labeling packaging, is a manufacturing process in which a printed label is placed inside an injection mold before molten plastic is injected. During molding, the label becomes integrated with the surface of the plastic product, creating the decorated container as part of the molding process.
Unlike a separate post-molding labeling process, IML combines molding and product decoration within the injection molding cycle. This makes it suitable for many plastic packaging products where integrated graphics, repeatable label placement and automated high-volume production are required.
How Does the IML Packaging Process Work?
A typical automated IML packaging cycle begins with label feeding and picking. The IML robot picks one or multiple labels from the label magazine and positions them accurately inside the injection mold using customized EOAT.
After the labels are positioned, the robot leaves the mold area and the injection molding machine completes the molding cycle. The plastic material forms the container while the label becomes integrated with the molded surface.
When the mold opens again, the robot can remove the finished IML containers and transfer them to the next production step. Depending on the project, downstream processes can include conveying, stacking, inspection or other automated handling.
What Plastic Containers Use IML Packaging?
IML packaging can be used for different injection-molded containers where decoration and molding need to be integrated into an automated production process. The mold, label and robot configuration should be designed according to the specific container geometry and production requirements.
Food Containers
Plastic Cups
Tubs and Boxes
Buckets and Pails
Plastic Lids
Household Product Containers
Chemical Packaging Containers
Industrial Plastic Packaging
Different applications may require different cavity layouts, label shapes, robot motions and EOAT designs. A thin-wall food container and a large plastic bucket, for example, normally require different IML automation configurations.
IML Robot, Mold and Label Integration
Reliable IML packaging production depends on coordination between the IML robot, injection mold, label and injection molding machine. Label dimensions and positioning must match the mold and container, while robot motion and EOAT should be configured for stable label picking, placement and finished-part takeout.
HecosTech can evaluate the complete automation process according to the customer’s container, mold cavities, label design, injection molding machine and production requirements rather than treating the robot as an isolated piece of equipment.

Complete IML Packaging Automation for Plastic Containers
An IML packaging system is more than an IML robot. Stable automated production requires the label, injection mold, injection molding machine, robot, EOAT and downstream equipment to be configured around the same container and production process.
Depending on the application, the automation system can include label feeding, automatic label picking and placement, molded-part takeout, conveying, stacking, inspection and other downstream handling. The required configuration depends on the container geometry, number of mold cavities, label design, molding machine and production requirements.
For new IML projects, evaluating these elements together before finalizing the equipment configuration can help avoid mismatches between the robot, mold, label and actual production process.
