HOT MELT SEALING

Advanced heating technology ensures gentle and uniform melting of various hot melt adhesives, preventing carbonization and guaranteeing superior sealing quality

PHOTOELECTRIC SENSOR

Provides real-time feedback to the PLC via sensors to instantly trigger self-protection to prevent defective output upon detecting missing, overlapping, or misaligned products.

PHOTOELECTRIC EYE TRACKING

Corrects film positioning in real-time via high-sensitivity photoelectric sensors to ensure accurate cutting trajectories, keeping the printed designs perfectly centered on the package.

PLC CONTROL

Manages operational configurations via a PLC program and a color touchscreen interface, supporting automatic fault diagnosis and real-time status monitoring.

VERSATILE FOLDING

It achieves various exquisite wrapping styles such as envelope and fold styles, suitable for square, rectangular, or trapezoidal products.
