Why do cooling fan manufacturers have to order several samples?

Customers who are new to the cooling fan manufacturer generally think that the cooling fan manufacturer should be able to find a few stocks at will, because this product is produced every day, but when the cooling fan manufacturer actually finds a sample, they say they will have to wait a few days. Can provide, why is this? 1. Most of the cooling fan manufacturers do not make this product every day, but do this type of cooling fan every day. For example, the cooling fan manufacturer may produce more than 20 types of cooling fans of different specifications and sizes in a day, and they will do 25* 25*10, one will make 30*30*10, another may be 80*80*25mm, and change the specification many times a day 2. And the same specification has many different parameters, such as 80*80*25mm, there are points Double ball bearings and oil-impregnated bearings have different voltages such as 5V, 12V, 24V, etc., as well as the same voltage and different speeds. It is difficult for us to confirm what voltage, what bearing, and what speed the customer wants, because every customer requires It’s not the same, maybe we would say, choose the commonly used 12V 80*80*25mm high speed, which is indeed the usage rate may increase by 10%, but the chance of being used is still very low 3. There are more than 50 different For cooling fans of different sizes, if you leave one for each size, and reserve about 10 as samples, it means you have to prepare 50 outer boxes to manage these 50 samples separately. For warehouses that originally had thousands of materials , The management cost must be increased again, and the spare samples of more than 50 models can be used for less than 20% in a month, because the customers targeted by the cooling fan factory are generally manufacturers of electronic appliances, most of them It needs to be tailor-made, as mentioned above, voltage, speed, bearing, cable length, terminals, etc., only a few are particularly urgent. For new products they want to try, they usually look for retailers as long as they have this size. , Give it a try, and get a general understanding in my heart. The main reason why cooling fan manufacturers do not stock samples is that they are not very useful. The cost of managing these samples is not as accurate as tailor-made for customers. They can only give up those who want to try them at will and only find the cooling fan customers in stock.
