Is it a cold heading plug screw?

The twisted "stalk" is very popular, but we don't agree with the ridicule of the outside world. Screw production is not as "simple" as online said. Although it is not so "sophisticated", it still needs a certain level of technology. Not everyone can say that he is "screw man".

Take the key step of screw production: forming process, cold heading, hot heading and turning are all screw processing methods, but why is cold heading the most suitable processing method for standard fasteners?

Of course, if you just want to be a "tool driver without feelings", then you can only operate without understanding the principle. But "salted fish has a dream", and it has to hit the level when twisting. You can't ask without knowing anything, so it's just a joke.

Here, the old "screw man" will talk about "cold upsetting" to friends who are "screwing".

The cold heading of screw is a process that the wire is extruded and deformed by external force, so that the wire becomes the required length and the nut is extruded. Cold heading is considered to be the most suitable additional process for producing standard fasteners such as bolts, screws, nuts, rivets and pins.

Because of its outstanding advantages, cold heading is an advanced production technology with high precision, high efficiency, high quality and low consumption, which can save raw materials, improve production efficiency and reduce costs, and is suitable for mass production.

Cold heading is a kind of screw that changes the wire into the required shape by plastic deformation of metal, which greatly reduces the loss of raw materials caused by cutting, improves the utilization rate of materials and reduces waste.
