Circular knife for slitter cutter

Goodklife Machinery Technology Co., Ltd Ma’anshan is located in Bowang Town which is one of the most famous town for blades in China, Goodklife has more than 30 years experience in this line. The company has been committed to providing knives and blades of high productivity and high precision. From raw material, heat treatment to finishing, Goodklife keeps track and exercises strict control over every piece, in order to improve the performance of our products and production efficiency, at the same time reduce the production cost.

Goodklife is specializing in shearing blades, slitting knives, fly shear blades, scrap shear blade and other industrial blades.

The products are widely used in steel industry, metallurgical industry and so on. Goodklife can produce shear blade with max length 5500mm and circular knives with max OD 1500mm, the knives can be made by qualified alloy tool steels, include 6CrW2Si, Cr12MoV, H13, D2, SKD11, SKD61 AND also Goodklife’s independent developed raw materials, G1, G2 and G3. These materials are excellent for high tensile strength, high hardness, high toughness and high hardenability. Accroding to most clients’ feedback, our G1 and G2 ensure much longer worklife, about 1.8 time and 1.4 time longer.

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.

The ESR remelted material improve following mechanical characteristics :

1. Improved toughness due to increased homogeneity and isotropy

2. Improved creep resistance properties

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

4. Improved purity

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.

No less than 40 sets 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.

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

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 .
