      Raw material:
    Xi'an gemei metal materials Co. Ltd. production began to control from raw materials, continuous selection of quality raw materials, product stability and consistency is very prominent. For different grades of raw materials, marking, marking the lot number. And for each batch of raw materials sampling inspection, inspection and filing. Ensure that the finished product has traceability, continuous improvement of product quality.


      Mixing Alloying:
    Xi'an gemei metal materials Co. Ltd. production milling process control is very accurate, with several large mixing machine and vibration platform, ensure milling and mixing process of materials can be fully stirred, to ensure the consistency of the internal organization of product.

      Pressing:
    Xi'an gemei metal materials Co. Ltd. production began to control from raw materials, continuous selection of quality raw materials, product stability and consistency is very prominent. In powder metallurgy, the metal powder is heated by the static pressure to form a blank, which is lower than the melting point of the main component, so that the connection between the particles and the method of improving the properties of the product is called sintering. Powder after forming, dense bodies obtained by sintering is a polycrystalline material, sintering process directly affects the microstructure of grain size, pore size and grain shape and distribution, is the core technology of powder metallurgy.

      Forging:
    The material can obtain a higher density and superior mechanical properties, and play a role in strengthening the surface. Accurately grasp the processing rate of tungsten and molybdenum materials, forging and forging temperature, is an important factor in gemei tungsten molybdenum material having excellent performance. Use of metal billets forging machinery pressure, the processing method of plastic deformation in order to obtain a certain mechanical properties, shape and size of forging. Forging (forging and stamping) the two part of. By forging can eliminate the casting defects such as loose metal produced in the smelting process, the microstructure is optimized, and the preservation of the integrity of the metal flow, the mechanical properties of forgings generally better than the same materials of casting.


      Rolling:
    In this process, the metal material is under the pressure of the rotating roller, which has a continuous plastic deformation, and the shape and performance of the section are obtained. Gemei has advanced tungsten and molybdenum cold and hot rolling technology and equipment from tungsten and molybdenum metal billet to the production of tungsten and molybdenum foils, gemei for you to ensure the production process is more advanced and more superior performance of metal.


    Machine processing:

    Gemei has such as cars, milling, planing, milling and other mechanical processing equipment and technology, made of tungsten and molybdenum materials to meet the requirements of various use requirements and surface.

    Lathe machining is a part of machining. The lathe is mainly used for machining of rotary workpiece. Can also be used in the lathe drill, drill reamer taps Banya and knurling tools for the corresponding processing.

    Grinding: divided into plane grinding and grinding. Plane grinding is mainly used for grinding plane, groove and so on. To grind the outer circle of the workpiece in a non abrasive grinding.

    Line cutting: cutting the workpiece by continuous pulse discharge.

    Deep impact: by pressing the press and die on the plate, strip, pipe and profiles, such as the application of external forces, so that the plastic deformation or separation, thereby obtaining the required shape and size of the workpiece forming process.



      Quality testing:
    Xi'an gemei metal materials Co. Ltd. products began to quality control from raw materials, and each process of quality inspection and sampling, ensure each process products quality inspection process control, finished product, material for the apparent size and internal tissues were detected in the products one by one, the stability and consistency is very prominent.
