Product Description

Slitting is a sheet metal cutting process with circular knives, which is used to split wide coiled sheet metal into narrower widths or for edge trimming of rolled sheet.The slitter knives are mounted on two arbors together with spacers .The spacers determine the width of the cut and the horizontal clearance. Sometimes also a vertical clearance (overlap) is used, e.g. to correct for bending of the arbors. Rubber stripper rings are used to eject the strip from between the knives and to support the strip during slitting.



Operational Progress :

Steel-choosing→Blanking →Forging Steel →Rough Processing →Heat treatment →Finishing→Testing


Knives are available with polished side faces ,High cost performance ,Punctual delivery .



Slitter knives are manufactured to a thickness tolerance of ±0.002mm-0.003mm(±0.00007 inch-±0.00012inch).

Parallelism tolerances is within 0.003mm (0.00012 inch) These are all prerequisites for the best possible slitting results.



Materials : 9CrSi ,6CrW2Si , H13 ,Cr12MoV ,G1 , G2 ,G3 and etc .


Steel-making by medium frequency furnace

Goodklife company can meet special requirements for materials . In order to guarantee the quality ,the company imported the spectrometer from Germany and is equipped with various testers,such as tensile tester,impact testing machine,metallography analyzer and so on .


Electro slag remelting

The largest ingot can reach 3 tons in Goodklife company .The ingot obtained by this remelting/refining process is very homogeneous and free of internal defects . The segregation of the ingot (called macro-segregations ) are substantially eliminated and the segregations of crystals (called macro-segregations ) are significantly reduced .

The ESR remelted material improve following mechanical characteristics :

   Improved toughness due to increased homogeneity and isotropy

   Improved creep resistance properties

   Best fatigue strength and tenacity properties as well as outstanding tensile strength

   Improved purity


Forging steel

The largest electro-hydraulic hammer is 4.5 ton .And more than 6 skilled technicians work for us .After forging ,the inside microstructure becomes much closer and the metal grain size becomes much smaller . It can evevate the characteristics and quality of the knife ensuring a longer life .


Rough processing

No less than 40sets of processing equipment in the rough processing workshop of Goodklife company , including lathe ,milling machine , planer , drill machine etc. Skilled workers are employed in its rough processing workshop .


Heat treatment

Goodklife company has independent workshop for heat treatment . Couples of skilled technicians work here . Actually , most blades ( thickness ≤100mm) can be fully hardened . Thus ,the blades can be used after repairing until the size reached the minimum design dimension .



Goodklife company has more than 35 sets of processing equipment including internal grinder , external grinder , surface grinder ,CNC grinder ,electric spark CNC wire-cut etc. The company can produce the shearing blades with 5500mm in length and slitting knives with 1300mm in outside diameter .



Various testers are put to use for testing its products in Goodklife company . They are including tensile tester , impact testing machine , metallography analyzer , harmless flaw detector , magnetic powder inspection , hardness tester , caliper rule , microcalliper , etc . Testing is carried out after each step . And every product has a unique track number . Thus it is easy to trace back anytime .

1. How many times can I sharpen my shear blade?

This depends on how much material is removed each time the blades are sharpened. A quality sharpening facility will remove as little material as possible to give you a sharp cutting edge. Most blades( thickness ≤100mm ) can be fully hardened in Goodklife . Thus ,the blades can be used after repairing until the size reached the minimum design dimension .


2. What types of material are used for shear blades?

Optional Materials :9CrSi , 6CrW2Si , LD , D2 , Cr12MoV , H13 , G1, G2 ,G3 and etc .

Goodklife has developed some high alloy steel ,like G1 , G2 ,G3 etc . They are new materials developed independently by our company and excellent in high intensity , high hardness , high wear resistance , high toughness and so on . They can be used in both cold and hot shearing ,the life is 2-3 times longer than other blades made of normal materials .



3. What is the difference between hardness and toughness?

Most steels can be hardened to some extent; however the resulting blade may be very brittle and unstable,then it is easy to crack. To avoid this alloying materials are added (alloy and tool steels) to allow for a hard stable blade. Hardness can be directly measured and expressed on hardness tester. Toughness is a bit harder to describe, as it is related to the steels unwillingness to be cut. Nickel is a good example as a tough material, it is quite difficult to machine, but can be dented with a hammer! The trick with blades and knives is achieving the hardness required to hold an edge, and not be as brittle as fracture on use. To this end alloying materials are added in different amounts and combinations to achieve the best balance for your application.
