paper container knives
We manufacture a comprehensive range of high-precision blades for the corrugated packaging and paperboard converting industries, including slotting knives, curved trimming blades, stitcher knives, and slitter-scorer blades. Designed for corrugated box printing slotters, corrugators, carton formers, and folding carton packaging lines. Crafted from top-grade SKD-11, SKH, high-carbon alloy steel, and tungsten carbide (TC), our blades undergo precision CNC curved grinding and vacuum heat treatment to deliver exceptional dimensional accuracy and wear resistance.
Our product lineup covers upper/lower slotting blades, curved serrated knives, and specialized mounting block assemblies customized to match your specific machinery. Engineered for clean, sharp shearing, our blades prevent fluting collapse and minimize paper dust generation to maximize high-speed boxmaking output.
Key Features: High wear & impact resistance, precise curvature geometry, clean cuts without flute crushing, reduced paper dust buildup.
Applications: Corrugated printer slotters, paperboard slitter-scorers, automated box-making machinery, and folding carton converting plants.
