The POLAR standalone die-cutter DCC-M operates on the counter-pressure principle, making it well-suited for handling special materials like plastic, metal foil, and large label formats. It’s particularly effective for semi-automatic offline label production, especially for small to medium run lengths, offering economic advantages.
Each individual stack is transported by two gripper fingers to the die-cutter. Here, the stack is initially pressed against the counter-pressure plate, which serves as the precise counterpart to the die. The compressed stack then passes through the die and takes on its final shape. Subsequently, the die-cut stack is conveyed via a shuttle to the banding unit, where it is banded.
Description
The highly adaptable and user-friendly POLAR LabelSystem DCC-M is designed for processing compressible plastic materials, including OPP foils for in-mold applications.
Workflow:
- Initially, the material slated for die-cutting is sliced into label stacks by a high-speed cutter.
- The pre-cut label stack is manually loaded into the feeder tray. Once the light curtain of the feeder tray is clear, two gripper fingers automatically convey the products to the die-cutting area.
- An integrated device lifts the stack during transportation to prevent the lowermost sheet from snagging.
- The counterpressure plunger piston, serving as the complementary counterpart of the cutting die, moves through the cutting die and presses the label stack, securing it on all four sides.
- Subsequently, the stamping punch pushes the compressed stack through the cutting die, shaping the material as intended.
- Finally, the counterpressure plunger piston ejects the stack from the cutting die, transporting it via a shuttle to the delivery unit.
Customer benefits
- Job change takes only 10 to 15 minutes with OptChange.
- Motorized precision adjustment of the cutting die enables tool-free operation at the machine.
- Achieving ultimate die-cutting precision involves aligning the stack on all four sides and clamping it before initiating the die-cutting process.
- Minimal material loss occurs because the stack remains locked between the stamping punch and the counterpressure plunger piston until it is unloaded.
