Daily Quality Management of Precision Casting Engineers

Daily Quality Management of Precision Casting Engineers

Casting is a complex process. Investment casting is even more advanced than precision casting. Due to the addition of wax molds and coating parts in investment casting, these parts have a significant impact on the quality of the castings (including dimensional accuracy and intrinsic metallurgical quality), so every process must be done carelessly. A slight relaxation may result in the previous work being abandoned. So, how can we do a good job in the daily quality management of a casting engineer. Today, precision casting manufacturer Tianyao Metal will talk to you about what needs to be done well as a precision casting worker in daily quality management work.

1、 To timely grasp the frequently recurring quality issues of products in daily production. In fact, products that frequently encounter problems in daily production may only account for 20% of the total number of products, but their impact on the overall situation accounts for 80%. This is the 20/80 law that we often hear about. According to this law, we must closely monitor 20% of the 80% market share. For example, for an important manufacturer with 100 items, we only need to grasp the 20 items that are prone to problems. The meaning of this sentence can also be understood as follows: we need to make 80% of the effort for these 20% products, while the remaining 80% products only require routine maintenance, which means we need to do 20% monitoring. This is also known as the Key Management Method, which emphasizes the importance and neglects the importance, and emphasizes the importance and neglects the small.

2、 It is necessary to track the entire production process of problematic products as much as possible and truthfully keep production records. Especially in areas that are inconsistent with normal production. We know that the instability of quality comes from variation, which is inconsistent with normal production. So, whether it's craftsmen or operators, they must strictly follow the process specifications and cannot improvise. In addition, production personnel must pay attention to operational details and record them in a timely manner. Otherwise, quality traceability will become a passive source of water.

3、 Investment casting engineers need to have a quick response mechanism and responsibility. Or rather, the power and courage of the "automatic stop" mechanism designed by the Japanese for production lines. Be willing to take responsibility, face challenges, and have the ability to stop. If there is a problem, production should be stopped immediately. It should not contain any ambiguity or ambiguity, to avoid causing batch scrapping. A quality event is greater than a day and cannot be perfunctory at all. We often see casting engineers busy and exhausted every day, which is an abnormal phenomenon, indicating that casting quality management is meaningless and that casting engineers work improperly. What the production site should do in quality management is to cycle through S (standard), D (execution), C (inspection), and A (action) to maintain production quality; Foundry engineers should consider the P (plan) D (execution) C (inspection) A (action) cycle to improve and enhance the existing quality. These are two different concepts and levels, and everyone should take responsibility and not be biased.

In actual production, we often see operators working with their heads down without looking at the direction, kicking the ball when problems arise, and shifting the responsibility onto the technical personnel. The technical personnel are full of grievances and do not know who to confide in. These are all bad examples. As a casting engineer, one should also have at least theoretical knowledge and practical experience in casting, clear thinking and judgment ability, sharp and profound insight, and the ability to see the root cause of problems through complex appearances. Of course, this requires time, accumulation, and dedication to achieve. But as long as you put your heart into it, you will definitely gain something. Since you have chosen the casting industry, then you should devote yourself wholeheartedly, no matter which process you undertake or what position you hold. In any industry, one needs to work hard, and hard work can bring rewards.
