Why Are The Offers So Different For The Same CNC Machined Parts?

In the process of quotation, we often encounter the same CNC machined parts,but the quotation is more than 1 times different? I believe we have found such problems. Our engineers base on the customer's requirements when we quote. If we are not clear about the customer's requirements, the cost must exists big difference, and the most common reasons for this are the following:

CNC Machining Materials

1. Different materials are used and prices are different. In the cost structure of CNC machining parts, the cost of materials is about 30%. According to different requirements and the selection of different materials, the difference between domestic materials and imported materials is 30%. This is one of the reasons. There is also the difference between secondary materials and new materials, which is what we often call the national standard materials and non-standard materials. They basically differ by about 15%.

CNC Machining Process

2. The difference in CNC machining method is also the reason why the cost has the greatest impact. According to the requirements and quantity of parts, the processing technology selected by each supplier is completely different. Some suppliers will not say it, and some will directly tell their customer, so we usually make DFM before the review. Selecting a reasonable process according to the customer's requirements has become the most direct way of cost.

Appearance Standard

3.Appearance standard requirements are different, which is very important, so many times suppliers quote prices based on their past experience, but they still do not clearly understand the customer's requirements, and often need to increase the price when make these parts, because this cost cannot do that, this is caused by insufficient understanding of the customer's appearance standards.

The above are direct reasons why the quotations vary greatly, thank you.
