Blades are available with ground, lapped or polished side faces.

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.


Parallelism tolerances is within 0.003mm (0.00012 inch)

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 .

FAQ

1.What's the price ?

Always we will quote you price based on drawings . Then according to your application and quantity ,we will send you quotation soon. 

For slitter knives ,we want to know following information :

  OD(mm)        ID (mm)         Thickness (mm)  Quantity (pcs)   Specified material
     

 

For shearing blades and others :

Length(mm)Width (mm)Thickness (mm)Quantity(pcs)Specified Material
     

In order to get the right offer , we have to check the drawing carefully in advance . If you don't have it , we have technicians who can make the drawing for you .

2.What's the material and hardness ?

Material and hardness are the most important thing to the work life of blades .According to your application ,we will recommend you the best material and hardness .

 

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 .

Hardness : optimum hardness and toughness after heat treatment . If hardness is high , when the blades meet higher tensile strength steel ,it is easy to crack . If the hardness is low , then the wear resistance is not good ,that means work life is shorter .  Actually ,most blades ( thickness ≤100mm ) can be fully hardened . Thus ,the blades can be used after repairing until the size reach the minimum design dimension .

3. What's the solution for crack or any other problems ?

If happen cracks ,then there are following reasons :

    a. The hardness is high .

    b. Used for cutting much higher tensile strength steel or others

Goodklife promise that will take responsibility for any failure caused by us ,and reproduce new blades for you for free .

Any other questions , you are welcome any time .
