In the forging industry in our country, there are a large number of quality issues, especially in some small enterprises that are unable to control product quality. Specifically, these problems mainly come from the following aspects:
- Inadequate material: Some unscrupulous manufacturers, in order to pursue profits or to obtain certain orders, will use inferior raw materials to produce forgings, resulting in a significant decrease in the quality of the finished product and which fails to meet customer needs.
- Size deviation: Due to improper production processes or inadequate process control, forging dimensions may deviate, seriously affecting the normal use of the product.
- Surface defects: During production, if not taken care of properly or if certain processing steps do not meet standards, forging surfaces will produce various defects such as oxidation, inclusions, cracks, and more.
- Failure to achieve intensity requirements: Due to the multiple influences of complex processes in forging production, the strength of some finished forgings may not reach the design requirements, requiring secondary processing to increase costs.
The above issues are generally prevalent in the forging industry and pose a certain threat to the stability and healthy development of the industry as a whole. Therefore, relevant departments should take effective measures, increase supervision, and ensure product quality.
Here is a specific case:
Company A, in order to catch up with orders, violated regulations by using inferior raw materials to produce forgings. Due to the lack of sufficient testing methods, this batch of forgings was sent to customers without undergoing strict quality inspection. As a result, two of the forgings underwent cracking during use, causing significant impact and loss to the customer’s production.
