1. Twenty-four years experience
2. We are END MANUFACTURER
3. We make steel by ourselves, so the materials are various
4. Forging steel make the inside microstructure become much closer and the metal grain size becomes much smaller to ensure a long worklife.
5. Competitive price
6. Passed the ISO9001 quality certification in 2001
7. OEM and ODM
8. Specializes in manufacturing all kinds of cutting tools, including slitting knives, shearing blades, wear-resistant furnace sliders, cutting blades, rollers, etc
9. Blade: Maximum length of 5500mm and maximum diameter of 1500mm
10. Materials5CrW2Si, 6CrW2Si, Cr12MOV, 9CrSi, H13 and self-developed H13k, HMB and HMK high various alloy steel
11. High intensity, high hardness, high toughness, and high hardenability, etc.
12. Widely used in industries of steel, rubber, papermaking, and so on.
13. Each technical index reaches the international standard.
Operatinal Progress:
Steel-making_ Blanking_ Forging Steel_ Rough Progressing_ Heat Treatment_ Finishing_ Testing
We manufacture shearing blades up to 6500mm(255.905inches) in length for cutting sheet steel etc.
Jinhai company has one independent R&D department which is fully equipped with experimental and testing facilities. Until now, we have developed some high alloy steel, like HMB, HMK etc. They are new materials independently developed by our company and excellent in high intensity, high hardness, high wear resistance, high toughness, high hot hardness and so on. They can be used in both cold and hot shearing and have been rewarded the national invention patens. The life of blades and knives made of HMB and HMK is 2-3 times longer.
Jinhai Metallurgical Machinery Building Co., Ltd. Ma'anshan established in 1988, is one of the leading enterprises specialized in the production of various cutting tools, including cutting blades, rollers, wear sliders, which are widely used in industries of steel, rubber, papermaking, and so on. At present, it occupied an area of 55, 000 square meters and has more than 160 employees and no less than 140 sets of processing equipments. The company has passes the ISO9001 quality system certification in 2001.
The materials have a wide range of 5CrW2Si, 6CrW2Si, Cr12MOV, 9CrSi and H13. Even early in 1996, the company established its R&D department and developed independently H13K, HMB, HMK and HMA high alloy series with the features of high intensity, high hardness, high toughness, and high hardenability, etc. The incision is smooth without burr and has a long working life. Each technical index reaches the international standard. The products has been sold widely at home and abroad.
