embossed using a variety of wire production ( usually lead, brass, such as H59, 3604,3602) produced brass nut . our daily exposure to embedded roll flower brass nut are precision automatic lathe machining. Knurled brass nut embedded reference standard from GB GB/T809.
Embedded knurled brass nut primary operating mode is injection molding, heated or embedded directly inside plastic mold injection , if the mold injection , PA / NYLOY / PET melting point are above 200 ° C , the nut is embedded into the plastic melt after rapid temperature becomes higher , injection molding, plastic body hardens rapidly cooling crystallization , if the embedded nut still in high temperature , it is possible down to the brass nut and plastic contacting place to start is loose or cracks. Therefore, the embedded nut are used in injection molding brass nut instead of steel nuts.
embedded copper nut knurled outer lines forming in two ways , one is the use of copper raw materials after forming garland on equipment for production , the general pattern in this way to pull Road as the ruled, the other is the use of optical round copper material directly in the production process of tapping side edge embossing, this processing method can produce some non- standard size knurled brass nut , brass nut embedded embossing shape can be selected with the user , such as textured , character embossing, embossing and other rolling herringbone pattern road.
