For customers who are in contact with cooling fans for the first time, when choosing a cooling fan manufacturer for the first time, the first thing they know is the price. About 6-10. The price of a small plus workshop in the mainland is only about 3 yuan. Why is the difference so big?
1. If you buy imported fans, you may first say that they are of good quality and good. Most of the imported fans are ball bearings, which have high cost, long service life and stable quality.
2. Domestic first-line brands are much cheaper than imported ones, but the bearings are oil-retaining bearings, which have poor temperature resistance and dust resistance. Even if the domestic products use double ball bearings, the price is actually much cheaper, mainly because the reliability and stability of the products are still poor.
3. Why is the domestic small processing workshop so cheap? In addition to the low management cost, although oil-impregnated bearings are also used in materials, the accuracy of the bearing, the accuracy of the chip and the accuracy of other materials are all deviated.
Combining the above items, to summarize, no matter who makes it, the cooling fan will rotate and have the same shape, but the difference lies in some details, such as noise value, air volume, firmness, high pressure and high flow resistance, temperature resistance, service life, defective products Rate and so on. Of course, the production here does not mean that the expensive ones must be good. Some manufacturers of cooling fans are not. Their prices are very low, the materials are used well, the profit is very low, and the factory management is also very good, but the profit is very low.
