Internal quality inspection of forgings

Because the characteristics of the forgings are constantly applied pressure to shape the metal, he needs a very high demand for quality, which means that the forgings must have a higher quality standard to meet the daily work use. So we also have high requirements for the inspection of forgings. Yongxin Forging Co., Ltd. simply introduces how to carry out the inspection.
The forgings are subjected to pressure, typically through the use of a hammer or pressure. The forging process builds fine grain structures and improves the physical properties of the metal. In the practical use of parts, a correct design can make the particle flow in the direction of the main pressure. Forgings internal quality inspection is to check the internal quality of the forgings themselves, is the quality of the appearance quality inspection can not be found, it contains both inspection of the internal defects of the forgings, also contains the mechanical properties of the forgings, and the important parts, key parts or large forgings should also be chemical composition analysis. For internal defects we will check through low power inspection, fracture inspection, high power inspection method to check whether there are forgings such as internal crack, shrinkage hole, loose, coarse crystal, white point, dendritic crystallization, streamline does not conform to the shape, streamline disorder, flow, coarse crystal ring, oxide film, stratification, overheating, burning tissue defects. The mechanical properties are mainly to check the normal temperature tensile strength, plasticity, toughness, hardness, fatigue strength, high temperature instantaneous fracture strength, high temperature durable strength, durable plasticity and high temperature creep strength.

Tong xin precision forging has a normal size and professional technology, strict with myself in every link, all the factory's products have strict quality requirements, if you have any needs, please feel free to contact us, we long to accumulate experience and reputation, won't let you down, and at the same time holding a sincere heart looking forward to cooperation with you.
