Inserted copper nut?

All kinds of embossed wire (general lead brass, such as H59, 3604, 3602) are used to produce copper nuts. Daily contact with embedded knurled copper nut are made of precision automatic lathe processing. The reference standard of embedded knurled copper nut comes from GB/T809.

The main operation method of embedded knurled copper nut is injection molding. After heating, it is embedded into the plastic parts or directly injected by the mold. If the mold is used for injection, the melting point of PA/ Nyloy /PET is at 200°. Above C, the temperature of the embedded nut is rapidly increased after hot melting into the plastic parts. After injection molding, the plastic body rapidly cools, crystallizes and hardens. If the temperature of the embedded nut is still at a high temperature, it is possible to loosen or crack the contact place between the copper nut and the plastic parts. Therefore, copper nuts are used instead of carbon steel nuts in the injection molding of the insert nuts.

Embedded copper nut outside lines knurling, there are two ways of forming a new copper go up again after flowers forming equipment for production of raw materials, general this way spent grain for the straight grain, another USES light round copper material production in the process of tapping and embossed directly, this processing method can produce some non-standard size knurled copper nut, embedded copper nut embossing shape with the user to select, Such as reticulate, eight-character embossing, herringbone embossing and other rolling patterns.
