How is the long pan head screws produced?

At present, there is only one manufacturer of long screws in Shenzhen, that is, Shi Shi Tong screw manufacturers. How did they produce the long pan head screws?

The way that Shi Shi Tong screw manufacturers produce long pan head screws is one-time cold forming using a die spotting machine. When the company puts the order of the long screws down to the workshop, the master responsible for the production will take the production drawings and the production checklist to see if there are any molds, punches, etc., and will talk to the relevant person in charge, let They booked it back.

Then take the relevant molds and wires for production. In the production of the long pan head screws, the material is cut first, and then cut to the top of the adjusted die spotting machine for cold heading, and the head shape, the groove shape and the rod portion of the screw are produced. At the same time, after the production, it is also necessary to measure the size of the relevant parts and fail, and then proceed to the next process after passing the test.

During the production process, there will be a thin mold line under the head of the screw. This mold line will not affect the assembly. However, some customers will not want this mold line, then we need an extra process to remove the mold line. After that, take the rolling thread again. Because the length of the long pan head screws is too long, it is necessary to manually put the screw on the root of the squeegee in the rolling thread. Not controlled by the machine.

After the finished rolling machine, if the customer does not require surface treatment, it can be packaged and shipped after cleaning. If the customer requires surface treatment, it can only be shipped after the surface treatment is completed.
