Corrugated slitter scorers, or corrugated board slitting machines, are used to slit corrugated boards into the proper shape, preparing for further processing. Fast positioning and precision cutting of the slitter scorers and blades during high operation speeds are of great importance. Tungsten carbide, or cemented carbide, is the ideal material of choice for manufacturing corrugator slitter knives thanks to its toughness and wear & impact resistance, resulting in high precision cutting and long service life.
Tungsten carbide is a mixture of tungsten carbide powder and cobalt powder. The cobalt is acting as a binder to bind tungsten carbide particles together. There are several processes to producing tungsten carbide, including wet grinding, drying, granulation, pressing and forming, HIP sintering, and sandblasting. Each material has its own properties, thus determining the ultimate properties of tungsten carbide.
