HOW IT WORKS

Mastering the Leading Technology

  • NingBo YinZhou ChengEn Machinery CO.,Ltd.
    Prepare suitable raw materials according to the material type and specifications of the shaft to be forged. Commonly used materials include steel, aluminum alloy or other alloys. • Ensure the quality and purity of the raw materials, and avoid using materials containing impurities or defects.

    1. Raw Material Preparation

  • NingBo YinZhou ChengEn Machinery CO.,Ltd.
    Make a die that meets the requirements according to the design drawings and actual needs. • The design and manufacture of the die must be precise to ensure that the metal billet flows smoothly in the die and avoid defects such as folding and cracking.

    2. Die Preparation

  • NingBo YinZhou ChengEn Machinery CO.,Ltd.
    Heat the metal billet to a suitable temperature for forging. • Control the temperature and heating time during heating to avoid undesirable phenomena such as overburning and oxidation of the metal.

    3. Heating

  • NingBo YinZhou ChengEn Machinery CO.,Ltd.
    Use suitable forging equipment to repeatedly hammer, squeeze and twist the metal billet to gradually form the required shape and size. • Temperature and deformation should be strictly controlled during forging to avoid defects such as overheating and cracks. • Forging methods can be divided into free forging, upsetting, extrusion, die forging, etc. according to the movement method of the blank.

    4. Forging

  • NingBo YinZhou ChengEn Machinery CO.,Ltd.
     After forging, the shaft forging needs to be cooled. • Choose appropriate cooling methods, such as air cooling, water cooling, etc., to avoid deformation or cracking caused by excessive local temperature differences. • Straighten some shaft forgings to eliminate stress concentration and correct the shape.

    5. Cooling and Straightening

  • NingBo YinZhou ChengEn Machinery CO.,Ltd.
    Perform strict quality inspection on each shaft forging, including appearance inspection, dimensional inspection, non-destructive inspection, etc. • Ensure that the shaft forgings meet the design and use requirements. • Accept the finished products of qualified shaft forgings and keep records; unqualified shaft forgings are repaired or scrapped.

    6、Quality Inspection and Finished Product Acceptance
