Why are so many machine screw suppliers rejecting Miss Nong?

Miss Nong wants to customize a machine screw, but in the early stage she needs samples to test, in order to know that this screw is not designed correctly. The order can be placed in the back. However, Miss Nong has found several machine screw suppliers, no screw manufacturers are willing to do it for her. They told the Miss Nong that the screw was not good and the quantity was small.

There is no way, Miss Nong once again found another machine screw suppliers. Later, Miss Nong found the Shi Shi Tong screw manufacturer and asked if we could make her machine screw and gave us the 3D drawing.

After measuring the size of Miss Nong’s wire screw, we found that the head size of the screw exceeded twice the thread and the polished rod portion was as large as the threaded portion. We said to Miss Nong, because this head molding exceeds the molding factor of the material itself, and the groove of the screw is large, leaving less than 1mm on both sides. At that time, there may be a head crack or a stripped screw head. It is necessary to use a multi-station machine, and it may not be successful. We also told the farmer about this problem. If we can’t do it, we will refund the mold cost to Miss Nong.

At the same time, we also told Ms. Nong that there is a mold fee, how much the mold fee is, and how much we will refund the mold fee. Miss Nong said that the mold fee she can accept, ask how long we can deliver. Because it is produced on a multi-station machine, it takes 9-12 days to customize the mold, so our production time is 15-17 working days.

After the payment of Miss Nong, we arranged the production. At the beginning, the screws that were punched out were basically not working, and the punching rods were also very fast. Then our technicians have been debugging the machine, carefully modifying the size of the mold part, and using a heater to heat the wire, so that the wire is not as hard as it is done, and it is better to do something. Until the screws made meet the requirements.

After receiving the sample, Miss Nong immediately took it and assembled it. She found that only one place needs to be changed. A week later, Miss Nong gave the Shi Shi Tong machine screw suppliers an order of 50,000 pcs.
