Long screw factory teach you how to distinguish its production mode

There are three production methods for long screws: welding production, multi – station production, clamping machine production. Different modes of production have their own advantages and disadvantages. So how can you tell their mode of production? Shi Shi Tong long screw factory teaches you.

Welding production. From the appearance, the welded screws seem to make no difference, but if you look closely, you can see that they are not straight and have small circles. This bulge is where the welding takes place. Weld the rods to the rods so that the length of the screws increases.

Mold closing machine production. The long screw factory produces the long screw through the mold closing machine will have the thin mold closing line under the head. This clamping line is not long and will not affect the assembly. So by looking at the head below whether there is a closing line can be judged whether the closing machine is produced.

Multi – station production. The long screws produced by the long screw factory in this way will not have a closing line under the head, nor will there be a bulge on the rod, is directly formed. But this method of production has limits on length and is more expensive.
