How IML Machine works

An IML (In-Mold Labeling) machine is used in the process of in-mold labeling, where labels are placed inside the mold cavity before the injection molding process. Here's a breakdown of how the IML machine works:

1. Label Insertion

Labeling: A pre-printed label is placed inside the mold cavity. These labels are typically made of polypropylene (PP) or other materials compatible with the molding process.

Automation: In modern IML machines, robotic arms or other automated systems handle the precise placement of labels into the mold. The machine has a system that ensures the label is perfectly aligned and positioned.

2. Injection Molding

Mold Closure: The mold closes, and molten plastic is injected into the mold cavity where the label is placed.

Adhesion: As the plastic cools, it bonds with the label. The label becomes an integral part of the molded product, without the need for additional adhesives or processes.

3. Cooling and Ejection

Cooling: The mold is cooled to solidify the plastic and allow the label to stay attached firmly.

Ejection: Once the plastic has cooled and solidified, the molded part is ejected from the mold, with the label securely attached.

4. End Product

The final product has the label embedded inside the plastic, providing a durable and long-lasting labeling solution.

Key Benefits:

Cost-effective: Reduces labor costs by combining labeling and molding into one step.

Durability: The label is protected from wear, abrasion, and environmental factors.

High-quality appearance: Produces clean, sharp, and aesthetically pleasing labels.

This process is commonly used in packaging, particularly for products like containers, tubs, and bottles, where high-quality and durable labels are needed.
