In the process of production, as long as it is manually operated, there is a possibility that errors may occur, resulting in quality problems of the produced products. For example, when producing hinge screw products, there are some problems such as crooked heads, out of roundness, etc. So what are the reasons for these situations?

1. The head of the screw is not round. The reason is that the selection of the first punch of the screw mold is improper or the punching is not full enough.

2. The screw has burrs or burrs. The reason is that the first punch is not well formed, mainly caused by the excessive gap between the punch and the die hole or the punch is too short.

3. The head of the screw is crooked. The reason for this is the poor installation of the screw mold and the improper adjustment of the machine.

4. The screw head is cracked, and the screw head is cracked. The reason may be that there is a problem with the quality of the screw wire itself, so before the screw wire is headed, the quality department must check it and use the potion. Especially the stainless steel screw wire, it is necessary to check that it is stainless steel 201 and that is stainless steel 304. There may also be a fault in the use of a die, as well as the failure of the viscosity of the lubricating oil.
