Why do the flat head machine screws require the cost of the mold?

Mr. Ning contacted the Shi Shi Tong screw manufacturer a few days ago, saying that he wants a flat head machine screws, the grooved inner plum, the head is 90 °, #4-40*12 stainless steel passivated.

According to Mr. Ning’s description, we quickly handed out a simple sketch to Mr. Ning to confirm whether this shape. After reading our sketches, Mr. Ning said that it was not this shape. Soon Mr. Ning gave us the sketch of his painting. We found this flat head machine screws with a cylinder on the head, which is about 2mm high.

After reading Mr. Ning’s drawings, we told Mr. Ning that the flat head machine screws should be opened, and asked whether Mr. Ning could accept the mold cost, and the mold was mainly used to form the head of the screw. Mr. Ning said that he knew that he had to open the mold and could accept the cost of the mold. Let us quote the price to him.

Mr. Ning received the price and said that he accepted our price, let us give him a contract, the contract is the price including tax and shipping, he will pay before next week.
