Iml labeling machine

Types of IML Labeling Machines

An IML labeling machine creates in-mold labels that both serve as branding for the product being packaged and function as part of the packaging itself. These labels are typically made from polypro and other plastic compounds, which are then attached to the container during the molding process.

Separating the label application process from the mold creation saves manufacturers both time and money, while also improving labeling efficiency and producing a better-end product. The types of IML-labeling machines can be split up into the kind of product they are meant for and the kind of technology they use.

• Robot arms: These machines typically use one or two labeling heads that can be repositioned and programmed to label products of different shapes and sizes each at around 2,200 to 4,000 pieces per hour. They work best for products with more complex packaging shapes and are more flexible than other options but less scalable to bigger production sizes.
• Sliding tables: This labeling machine comes with a built-in sliding table to assist in product orientation and can handle around 1,000 to 3,500 pieces per hour. This system works well with products with flat and panel surfaces and will typically come with electronic controls so that operators can change the speed and position of the sliding table to suit their needs.
• Rotary tables: A rotary IML labeling machine will use an indexing technology to intermittently stop products at the labeling station. This table can handle 3,000 to 8,000 pieces per hour and is usually customizable with different label applications, feeding systems, and product fixtures to accommodate various products and labels.
• Automatic Turret: An automatic turret labels products by using vertical turrets and is best suited for cylindrical and round products. It can usually handle around 6,000 to over 10,000 pieces per hour. The vertical turret usually has multiple stations that carry and present products to the labeling mechanism, and the labeling mechanism can then apply labels to the product at each station.

The above are some of the IML-labeling machines based on their methods of labeling. Others are categorized by product shape and size.

• Flat IML labeling machine: Used to label flat containers like buckets, boxes, and other container shapes with flat mold areas. These containers also come with the flat labels that are typically printed directly on the container.
• IML labeling machine for clamshells: A clamshell IML label is an imprinted label to be read upon opening a clamshell container. When properly designed, the imprinted label will not wear or rub off when the container is opened and closed repeatedly.
• IML labeling machine for transparent containers: In-mold labeling has become an increasingly popular labeling choice for clear containers. In-mold labels are made of high-clarity, super-clear polypropylene that won't interfere with the product's visibility.

  The IML labelling machine may have various automaticness levels, including fully automatic, semi-automatic, etc. The fully automatic machine can carry out automatic feeding, labelling, and delivery processes, which helps to reduce manual intervention and improve production efficiency.

Maintenance

For keeping the working performance, working efficiency, and service life of the in-mold labeling machines, regular maintenance is quite important. The following are some routine maintenance tips:

• Daily check and cleaning

  Users should inspect the machine daily. They should check whether there are any loose or damaged parts, making sure the label and marking material supply systems work properly, and ensuring the machine's driving and electric systems are error-free. Users need to clean the residue and dirt on the label and marking material feeding paths, guiding tracks, and printing heads to avoid blockage and quality issues.

• Periodic parts replacement

  Users should periodically replace the wearing parts (e.g., the feeding belts, guiding tracks, and the printing head's nozzles). The replacement is essential for ensuring the stability, smoothness, and accuracy of the labelling.

• Lubrication

  Perform regular lubrication on the moving parts and transmission system of the in-mold labelling machine. Apply the proper lubricant as per the machine's manual to ensure smooth operation and reduce wear.

• Electric system maintenance

  Check the wires and connections of the electric drive system and control system periodically to ensure they are in good condition and properly secured, thus avoiding electric leakage or circuit faults.

• Regular calibration

  Users need to calibrate the position, precision, and alignment of the label and marking material printing units. Regular calibration is necessary for ensuring the machine's precision and labelling quality.

Scenarios of IML labeling machines

Due to their numerous advantages and uses, IML labeling machines have found a broad spectrum of applications in several industries, specifically for container labeling.
