The thing about the cooling fan-tapping teeth

Back to list Release date: Jul 30, 2020

Tapping is a process used in the outer frame of cooling fan.


There are two popular materials for the outer frame of cooling fan :aluminum alloy and plastic.Generally, when we say metal frame, we mean aluminum alloy.


On the opening of installation mode, there are two options for aluminum frame, one is nut type, and the other is tapping thread, which can lock the frame directly.If the size exceeds 200mm, it is recommended to choose the locknut type.Because of the too large motor fan shape, its shaking strength will be stronger under working conditions, and the fan will loosen after working for a long time, which will cause the equipment to work abnormally.


Locking screw teeth are not recommended for plastic frame, which is softer than aluminum frame.Locking screw threads will easily lead to loose sliding teeth and unstable fan.Whether the frame is processed with screw teeth will be customized according to the customers requirements.
