? Company Information ? Goodklife Machinery Technology Co., Ltd Ma'anshan is located in Bowang Town which is one of the most famous town for blades in China. 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. By working with counterparts from western countries closely, Goodklife continues to innovate and pursues the better quality. Besides standard raw materials like 9CrSi, D2, H13, the company also has its own special materials which are specializing in processing high tensile strength metal coils. Material-choosing, cutting performance improvement, professional advices are available here. Good material, skilled producing process and responsible after-sale service make our products popular at home and abroad. ? ? ? Product Description ? We manufacture circular disc knife for paper slitting works . The materials are various , 9CrSi , HSS and etc . ? ? 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 . ? 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 . ? Finishing 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 . ? Testing 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 . ? ? ? Packaging & Shipping Packaging :?? A.?Inside packing: Applied with?anti-rust oil?and then packed in?plastic bag ? ? B.?Outside packing:?Packed in plywood case ? ? ? Shipping : FOB , CIF , DAP and etc. According to customers' requirements ,we will send out the goods to the forwarder that ready for delivery . ? ? Our Services Material and hardness are much important to the work life of ?blades ,according to over twenty years' experience ,Goodklife can provide you professional advice . We will recommend you best material and hardness according to the applications of blades .We want to know the following details : ? ? What kind of the steel ? ? ? The maximum tensile strength of the steel ? ? ? The minimum and maximum thickness of the steel ? ? ?? We custom blades according to your drawing or description .In order to provide prompt and accurate quotation , it's better that you can provide us the?quantity , drawings , cutting application and etc?of blades . ? All of your inquiry and emails , we will give reply within 24 hours . No excuse for failure ,only the action for success.? ? Our enterprise spirit :?Mutually beneficial cooperation?. ? ? 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 :

?	?	?	?	?

? 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 . ? ?
