Could the long brass socket screws not open the mold?

For some customers, if it is a long brass socket screws that needs to be opened, they do not want to pay for the mold. Because they feel that the quantity they need is very small, and the subsequent order quantity is not many, if they pay for the mold cost, their purchase cost will increase a lot. So can the stainless steel long screw not open the mold?

Generally speaking, if the long brass socket screws is produced by cold heading, it needs a mold to be formed. Some mold screw manufacturers have it, so there is no need to open the mold, if it is a mold that the screw manufacturer does not have, then it needs to open the mold. And to judge whether a screw needs to be opened, it mainly depends on whether the screw manufacturer can produce the screw required by the customer through the existing mold. If the existing mold cannot be produced and a new mold needs to be ordered to produce it, then it is necessary The mold is opened.

But sometimes the long brass socket screws do not need to open the mold, so it is produced by turning, but if it is produced in this way, the problem of the screw groove shape needs to be solved. Either the groove is punched out by a punch, or the head is produced by cold heading, and then processed by turning. However, if the number of production methods of turning to process is relatively large, the cost will be very high, and the production time will be very long.
