Hello, everyone! I am Jason from Shenzhen In-sail Precision Parts . Today, I will talk about several common types of brass insert nuts and their respective installation methods. Some readers maybe have some doubts about the types and installation methods of some nuts. Aren't they similar ? What's the difference? ....
Normally , brass insert nuts Have four installation methods
They are ultrasonic/ heating staking installation method), press-in installation method, self-tapping (installation method and Molded-in installation method. Today, let's talk about ultrasonic/heat staking threaded insert.
The products in the figure are all installed by ultrasonic/ heating staking implantation. Most of the surface knurls are double knurls, horoscope and herringbone, and some are designed as diamond-shaped diamond knurls. In the figure, you can find that some nuts have a flange on them ; Generally, this type of products are selected, and most of them require appearance; In addition, some products are made of stainless steel, indicating that brass nuts are not only made of brass, but also stainless steel and iron can be processed.How are these products installed? Please look at the picture.…
These products are all installation into plastic parts, that is to say, a hole is reserved in the plastic part. The brass nut is heated by electric heating or ultrasonic heating to soften the periphery of the plastic hole, and then it is pressed into the hole to cool and form, and part of the nut has an outer circle. They all have a certain taper, just to play a guiding role when pressing in. There is also an ultrasonic method. The reason is the same as heating, except that the brass nuts is heated by sound waves. Of course, ultrasonic has another advantage. It can make the brass nut and the plastic part better bond, thereby making it stronger.
