When we are building high-strength screws, we sometimes find that white residues appear on such screws, and these residues are phosphides. The reason for the occurrence of such a substance is that the high-strength screw is not cleaned with acid cleaning agent during the manufacturing process, and the rinsing tank is not inspected, and such production problems may also occur.
For the production of large-size fasteners, it is generally necessary to go through the production process of quenching with polymer aqueous solution, but if it is to use alkaline cleaning agent to clean the fasteners of large specifications before it is quenched, then we You will find rust on the inside of the fastener. The solution to this problem is to change the rinsing liquid to ensure that the fasteners will not rust when they are not in use.
When installing pressure rivet nuts, be sure not to tighten them before the anodized aluminum plate is installed, let alone remove the burrs on the fasteners in advance. As for the above problems during installation, they usually happen to some novice installation masters. Therefore, it is recommended here that for newly appointed masters, we must do a good job of relevant knowledge training to avoid installation problems in some details, which will affect the continued use of fasteners.
When installing the fasteners, we should not think that the tighter the squeeze, the better the fastener installation effect will be. We must know that once there is excessive squeezing, it will flatten the head of the rivet nut. Once the thread is deformed, the nut is a waste product. The reminder here is that before mass production of such fasteners, the placement force must be determined in advance.
Automotive fasteners mean that we all know that for the processing and manufacturing of any kind of mechanical parts, only on the basis of ensuring the quality, can we better improve the productivity and ensure the efficiency of production. In the process of manufacturing and remanufacturing of each kind of parts, there will be some relatively easy problems. Only by avoiding these problems can the quality of production be guaranteed. Here, the flange manufacturer briefly introduces the problems that are more likely to occur when creating fasteners.
