Due to the excellent electrical conductivity and heat dissipation of copper screws and aluminum screws, they are widely used. However, there are not many special screw factories specializing in the processing of copper screws and aluminum screws in China. The processing factory of standard screws and special screws has many years of processing experience. In this regard, we are willing to share the experience accumulated over the years to jointly promote the processing level of the domestic special screw industry and participate in the international competition.
First of all, the process principle of copper wire is similar to that of steel wire. The main thing is that when buying copper wire and aluminum wire, you have a definite order to order the raw material. If there is no order, do not prepare inventory, otherwise the raw material may become waste copper and aluminum, which will be wasted huge. Secondly, pay attention to aluminum wire and copper wire. Copper and aluminum are very soft. Aluminum scraps and copper scraps are very easy to stick to the mold cavity and cause scratches on the finished product. This reduces the chance of sticking. In addition, during production, (solid, powder,) lubricant should be sprayed on the surface of the aluminum material to minimize the phenomenon of sticking to the mold. In the end, no matter how hard you try, it is impossible to completely guarantee the non-stick film, so you can only watch the production with one person and one machine. When the sticking mold occurs, stop the machine immediately to remove the aluminum scrap and start the production again.
