Product Description
OME & ODM Finishing Tungsten carbide core nibs
Key Specifications/Special Features:
Tungsten Carbide Cold Forging DiesOutside diameter, inner diameter, height are all accurate grinding, tolerance can be +0.01mm.The product has very good concentricity, parallelism, perpendicularity.
Our advantages:
1. Made by virgin raw material. Our production line is imported, the service life time of product is higher by 120%.-
2. Don't crack.
3. HIP (Hot Isostatic Press) sintering ensures the stable microstructure, the service life time is longer, die change is less, can improve the working & production efficiency.
4. We also supply carbide dies with coarse grain size, which has high impact resistance ability and can be used to make big size carbide dies.
The cost is reduced by increasing tool life and productivity is improved.
The defect rate is reduced and quality is improved.
High fracture toughness----------- lower crack occurrence
High strength and hardness-------improved tolerance of colt
Low friction coefficient--------------improved surface roughness
Tungsten carbide grade selection
In the standard tungsten carbide cold heading process, tungsten carbide cold heading die need to withstand greater shock, in order to meet the requirements, you must use the tungsten carbide with a higher amount of cobalt-containing, high strength and good toughness. Such as YG15, YG20, YG20C, YG22C, HJ80.1 (GT55).

Also we can produce the carbide die as your required.
| Carbide production The productionprocess of powder-metallurgical products basically includes the four steps of powder preparation, forming, sintering andfinishing. Tungsten carbide production The APT (ammonium para-tungstate) is calcined into tungsten oxide under high te-mperature. Subsequently the oxide is reduced to tungsten metal in a hydrogen atmosphere. The metal powder is then mixed with carbon and carburised under inert atmosphere at high temperatures. The production parameters are decisive for the WC grain size in the sintered carbide. Powder preparation The tungsten carbide is intensely mixed with the binder metal cobalt, nickel or iron, various grain growth inhibitors and materials, which promote compaction, by wet grinding so that a homogeneous suspension is created. Afterwards, the suspension is dried in a spray tower to produce a granulate with good flow characteristics. This granulate represents the basis for all forming processes. Metal forming The objective of the forming process is to obtain a near net shape sample. Pressing is normally carried out at room temperature with pressures reaching up to several tons per square centimetre. There are several ways of pressing blanks: During isostatic cold pressing the powder is filled into an elastic flexible hose and pressed into a compacted form through high liquid pressure. The powder blocks which are produced in this way can then be processed mechanically. All common machining methods like milling, cutting, drilling or turning may be applied. In uniaxial pressing the pressing tool consists of a die and an upper and a lower punch. The carbide powder is filled into the die and then compacted to create the so called green carbide, which is ejected from the pressing die. Extrusion pressing is mainly used to produce rectangular bar or cylindrical rod, with or without axial hole(s). A plasticiser is added to the powder. The resulting paste is pressed through an extrusion nozzle. Before sintering, the plasticiser must be evaporated in special drying furnaces. Metal Injection Moulding (MIM) is a process used to produce more complex forms which cannot be produced by direct pressing. The paste preparation is similar to the extrusion process. Sintering process The sintering process converts the blank into a homogeneous and dense carbide with a high level of hardness. The material is sintered at temperatures between 1,300 and 1,500 °C (liquid phase sintering) and sometimes also at high pressure (up to 100 bar). The volume is reduced by up to 50 % during this process. Finishing In order to achieve the final requirements of surface finish, tolerances, etc. carbide parts can be subjected to a series of finishing processes such as grinding, spark erosion and coating. |
