In aerospace, energy, automotive and many other high-end fields, precision forgings as the core parts, its quality control is crucial. Ensuring the quality of forgings is not only about the performance and safety of the final product, but also about the reputation and sustainable development of the company. This paper will focus on the quality inspection methods and related standards of precision forgings.
Quality testing methods for precision forgings
Visual inspection: Visual inspection is the most elementary inspection method, mainly relying on the operator’s experience to identify obvious defects on the forging surface, such as cracks, folds, burrs, etc.
Non-destructive testing: including X-ray testing, ultrasonic testing, magnetic particle testing, eddy current testing and so on. These methods can detect internal defects and structural integrity of forgings without damaging them.
Destructive testing: such as tensile test, impact test, hardness test, etc., through destructive or expendable means to evaluate the mechanical properties of forgings.
Dimensional accuracy detection: The use of coordinate measuring machine, laser measuring instrument and other high-precision equipment to accurately measure the size of the forging to ensure that it meets the design requirements.
Quality control standards for precision forgings
International standards: such as ISO, ASTM, ASME, etc., these standards provide general requirements and guidance on metal materials, forging processes, and product quality.
Industry standards: aerospace, energy, automotive and other industries have their own quality standards, such as AMS, ASTM E and other standards in the aerospace field, which have detailed provisions on the performance, reliability and detection methods of precision forgings.
Enterprise standards: on the basis of meeting international and industry standards, enterprises often develop more stringent quality control standards according to their own product characteristics and market demand.
In order to meet these standards, production enterprises need to establish a sound quality management system, from raw materials to the final product delivery, every link needs to be strictly checked. At the same time, we should continue to introduce advanced testing equipment and technology to improve the accuracy and efficiency of testing.
The quality control of precision forgings is a systematic engineering, involving raw material control, process optimization, equipment advancement, testing technology and many other aspects. In order to ensure the high quality of forgings, enterprises must always adhere to quality standards, constantly improve the quality management system, and introduce advanced testing technology and equipment. Only in this way can we remain invincible in the fierce market competition and make greater contributions to the development of high-end manufacturing industry.
