In the cardboard and packaging industry, high-precision slitting and corner trimming are critical to ensuring product quality, consistency, and production efficiency. From processing whole cardboard trays to trimming neat round corners for cards and paperboards, specialized automated equipment eliminates manual errors, streamlines workflows, and meets stringent industry standards. Two professional machines—the HX2100A Fully Automatic Paper Board Slitting Machine and HX120 Automatic Four-Corner Round Trimming Machine—work in synergy to provide a comprehensive cardboard processing solution for packaging, printing, and stationery industries.

The HX2100A Fully Automatic Paper Board Slitting Machine is engineered for high-precision, efficient processing of cardboard materials, seamlessly integrating vertical and horizontal slitting into one continuous operation. Its fully automated workflow starts with automatic loading of whole trays, followed by precise vertical slitting, automatic material turning for horizontal slitting, and ends with automatic stacking of finished products. This one-stop automation eliminates manual intervention, significantly boosting production efficiency.

A key advantage of the HX2100A Fully Automatic Paper Board Slitting Machine is its exceptional slitting accuracy and consistent board strip quality, supported by a user-friendly digital knife adjustment ruler that enables quick setup changes. This ruler allows operators to adjust slitting specifications efficiently, reducing downtime between production runs and ensuring consistent results across diverse cardboard sizes and thicknesses.

Complementing the HX2100A, the HX120 Automatic Four-Corner Round Trimming Machine boasts an industry-first maximum trimming height of 120mm. It adopts an innovative “dual-sequence trimming” process to address uneven corner sizes and stringent material tolerance requirements: first trimming two corners on one side, then precisely repositioning the material to trim the opposite two.

Driven by a high-power pneumatic system, the HX120 ensures stable operation, automatic feeding, and precise trimming with enhanced safety. This process delivers uniform, smooth-edged round corners, virtually eliminating irregularities and burrs—even on stacked materials like cards and paperboards. Its high trimming height also expands its applicability to thicker cardboard products.

Together, the HX2100A and HX120 form a seamless cardboard processing workflow: the HX2100A handles high-precision slitting of whole cardboard trays, while the HX120 adds professional round corner trimming for finished products. Their complementary functions streamline production, reduce labor input, and ensure consistent quality, making them essential for modern cardboard processing factories.
