Is the long black screws to open mould?

When many customers are looking for screw manufacturers, it is estimated that most people want their screws to have molds, so they save the cost of the molds and reduce their procurement costs. So, does the long black screws open mould?

Whether the long black screws needs to open the mold, look at the size of several places:

One is the diameter of the rod of the screw. The diameter of the rod not only determines whether it is necessary to open the mold, but also affects the cost of the screw and the cost of transportation. Therefore, the diameter of the rod is very important. If the diameter of the stem is the same as the diameter of the thread, it is usually necessary to open the mold. But if the screw manufacturers have produced similar dimensions, then they have molds, so there is no need to open the mold.

One is the length of the thread. long black screws are molded at a time using a mold clamping machine at the time of production. The mold clamping opportunity pinches the length of the thread. If the mold is not that long, then the mold needs to be opened.

One is the size of the head. If the size of the head does not follow the standard, then it is also necessary to open the mold.
