Tungsten carbide razor knives have outstanding properties such as long life and clean cutting, although they are not as shock-resistant as steel knife.
By optimizing the ratio of Cobalt to Tungsten Carbide and the Tungsten Carbide particle size, SRC produces tungsten carbide razor knives with improved toughness (or shock resistance) and wear-resistance.
Toughness & Shock-resistance
TC razor knives are extremely wear-resistant if chipping and breakage are avoided. With optimum TC grade selection, SRC razor knives are tough (or shock resistant) enough to operate successfully in double-wall or tri-wall board production without the inherent brittleness.
There is no single blade material that is appropriate for all the applications in the corrugated board industry. SRC offers wide range of TC razor knives and optimizes the hardness, angle of the blade and thickness of the knife to ensure the right mix of properties for each individual application.
To get the best performance from TC razor knife it is really important to prevent glue, oil and paper dust from sticking to the surface of the knife because it may interfere with the periodic sharpening of the blade and the balance of the knife. In order to mitigate this undesirable effect, we adopt the high-gloss finish of the surface of the knife.
Thorough quality control
Procedure includes cross-section microstructure test, density test, magnetic saturation test, coercive force test, bending test, wear-resistance test, and etc
