Shear blades

KnifeSol shear blades are made from special ESR pre-materials using special tool steels. All forging and heat treatment operations are performed in the same factory that produces knives. This specific choice is required to obtain the best structure and mechanical features for knives in order to improve their quality and to extend their life.

KnifeSol is able to meet all types of plant processing characteristics and customer needs.

Metal spacers

KnifeSol metal spacers are in 9CrSi material and have similar tolerances (flatness and parallelism) with circular knives. We believe that spacers should have the same core hardness, as circular knives, especially to maintain the same features on the shaft. What’s more, the tools (knives, spacers, rubber bonded steel spacers) are mounted and fixed to the shaft with a very high tightening load. Our spacers must therefore resist these loads. But the most obvious reason is that spacers must have a long service life, so we also consider the possibility of improper handling by workers that could easily damage the spacer, if they were not hardened at core.

Circular slitter knives

KnifeSol special feature that sets us apart from our competitors is that all our circular knives are made from the finest quality alloy steel, starting with ESR pre-materials. The ESR re-melting process improves the features of materials. The material’s structure is free of segregation and the inclusions content is significantly reduced. The ESR re-melted material also displays a more uniform distribution of carbides in the matrix; therefore mechanical properties are superior, allowing an improved durability of knives.
The ESR re-melted pre-material, combined with a special homogenization annealing treatment and forging operation with excellent deformation, elevates the characteristics and quality of knives, ensuring an extended service life.
KnifeSol’s selected basic standard technology is the best basic choice for knives’ life and differs from competitors products’ quality, since they mostly use only conventional melted materials with a view to increase profits. For your information: the material obtained from conventional melting process contains higher grade of segregations and higher grade of non-metallic inclusions, easily dectectable on micrographs. These imperfections are located on the knives’ perimeter, right where the material structure must be perfect in order to avoid fractures due to imperfections of the material. We distinguish ourselves from others since we offer a better basic quality. Finally, all forging and heat treatment operations are performed in the same factory that produces knives. We are able to meet all types of plant processing characteristics and customer needs.

KnifeSol circular knives are made only from round bars, to ensure the proper and best natural structure for the circular knives.

KnifeSol slitter knives are custom made. One of our strengths is the production of circular knives with a maximum outer diameter of 1400 mm.
