Why do cooling fan manufacturers have to order several samples?

Time：2021-09-09Views：0

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 random, because this product is produced every day, but when the cooling fan manufacturer actually finds the cooling fan manufacturer for samples, 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 make this type of cooling fan every day. For example, Jingyangda, there may be more than 20 kinds of cooling fans of different specifications and sizes that can be made in one day, and will make 25* 25*10, it will be 30*30*10 for a while, and it may be 80*80*25mm for a while, and the specifications are changed many times a day

2. And the same specification has many different parameters, such as 80*80*25mm. There are double ball bearings and oil-impregnated bearings. There are different voltages such as 5V, 12V, 24V, etc., as well as the same voltage and different speeds. It is difficult to confirm what voltage, what bearing and what speed the customer wants, because every customer’s requirements are different. Maybe we would say, choose the commonly used 12V 80*80*25mm high speed, this is indeed the utilization rate may increase 10%, but the chance of being used is still very low

3. There are more than 50 different sizes of cooling fans. If you leave one for each size, and reserve about 10 as samples, it means that you have to prepare 50 outer boxes to manage these 50 samples separately. For warehouses with thousands of materials, management costs 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 electronic Manufacturers of electrical appliances, most of them need to tailor-made, as mentioned above, voltage, speed, bearing, as well as cable length, terminals, etc., only a few are particularly urgent. They usually look for retail if they want to try new products. Quotient, as long as you have this size, try a little and you will have a general understanding.

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.
