Rotary shear knife for coil slitting line and edge trimming line

A sharp blade can make all the difference in your slitting and trimming process. Our range of rotary slitting blade is designed to improve accuracy, consistency, and efficiency of your process. These blades are suitable for slitting line and side trimmer line. We can provide high precision coil slitting blade according to your requirements.

We can make rotary slitting blade with max length 5500mm and circular knives with max OD 1500mm, tolerance of Outside diameter is ±0.01mm and Tolerance of Thickness: ±0.002mm. Hardness of the blade is provided as per the application requirements and we ensure optimum hardness for wear resistance.

Our range of rotary slitting blade is 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. Our G1 and G2 materials have ensured longer work life, about 1.8 time and 1.4 time longer. Our team can process the knives surface with lapping or polishing according to clients' requirements. If you need a quote for rotary slitting blade, feel free to connect with us.

1.Goodklife takes three steps to guarantee the quality of blades.

      A.ESR raw material.

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
      B. Forging every piece of blades .

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.

      C. Professional heat treatment technology

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 mini. design dimension.

Before delivery, we will check the quality for every piece of blade .According to our data for many years, we seldom receive claim about the quality of our products.

2.Goodklife accept third party inspection ,like SGS and etc.
In order to improve the customer experience and maintain strict standard in terms of product quality, Goodklife introduced SGS third party inspection institutions, to escort the product quality. All exports of products for exports must conform to the SGS quality standard, and through strict inspection and testing, product, process, system and service in accordance with national and international regulations and standards.

3.Goodklife has complete quality feedback system. 
Goodklife takes responsibility for any failure caused by us, and reproduce new blades for you for free. But we seldom receive claim about the quality of our products. Before the delivery, we will check the quality for every piece of blades. We will never send out products with problems while don't inform our customer.

4.Goodklife also provide analysis and solutions for shear problems.

We can provide technical service from our engineer to assist you in realizing a high quality output.
