For ordinary screws, we all know is a single mold machine head molding, then stainless steel special screws are produced by what machine?

If the screw is cold heading production, generally through the single mold machine, closing machine, multi – station for the production of blank. Specific is what kind of machine to carry on production, one is the dimension that needs to see stainless steel special screws and administrative will decide. If the diameter of the screw head is more than 2.5 times larger than the diameter of the thread, or if the screw has a step position, it is basically required to carry out multi-station.

If the length of the screw is very long, basically more than 100mm, then it is produced through the closing machine. If the die closing machine, before starting, you need to cut first, because the length of the stainless steel non-standard screw is too long, the machine can not cut such a long screw, so you need to cut separately in the cutting machine, and then put the cut screw into the die closing machine for production.

If some customers for stainless steel special screws tolerance requirements are very strict, then according to the size of the screw, or through a single mold machine to play the blank, then take the car processing or grinding machine; Or it can be produced by multiple stations and then taken to the car for processing.
