The issues that pay attention to the production of the full threaded stud are as follows;
The produced full threaded stud, due to which production aspect is unreasonable, is likely to cause the quality problem of the full threaded stud. In production, during delivery, many full-threaded stud quality problems may be found. Let's talk about the quality problems that full-threaded stud often encounters and what causes the quality problems. Finally, some solutions are proposed.
1. The full-threaded stud has burrs or burrs. The reason is that the first punch is poorly formed, which is mainly caused by the excessive gap between the punch and the die hole or the short punch.
2. The head of the full threaded stud is not round. The reason is the improper selection of the first die of the screw die or the insufficient filling of the first die.
3. The head of the full threaded stud is deformed and the head is skewed. The possible cause is the improper installation of the full threaded stud mold and improper adjustment of the machine.
4. The head of the full threaded stud is cracked, and the head of the full threaded stud is cracked. The reason may be the quality of the screw wire itself, so the full threaded stud wire must be inspected by the quality department and tapped with the syrup before heading.
Especially for stainless steel screw wire, it is necessary to check that it is stainless steel 201 and that is stainless steel 304. It may also be due to the wrong use of a die (such as a die with a hexagonal washer head for the pan head), and the viscosity of the lubricating oil is invalid. Full threaded stud head problem, high-strength full threaded stud fracture, or head crack detection. This article introduces some of the problems encountered in the head of the full threaded stud and how to detect the head problems of the full threaded stud.
The common quality reasons of the full threaded stud are of course not limited to the above, this is only a part of it. There are other quality issues, so I'll talk about them at that time. The above full threaded stud quality reasons are for reference.
If you encounter these problems, you can try the solutions proposed.
