In daily life, screws are ubiquitous. It is the foundation for fastening everything. It is a tool that uses the physics and mathematics of the slanted circular rotation and friction of objects to fasten fasteners gradually.
Due to the excellent electrical conductivity and heat dissipation of copper screws and aluminum screws, it can be used in a wide range of applications, such as the power industry, home appliances, lighting, etc., but there are not many special screw factories specializing in the processing of copper screws and aluminum screws in China.
First of all, the principle of playing copper wire and steel wire rods is similar. The main reason is that when you buy copper wires and aluminum wires, you have to make certain orders. You must order raw materials. You can order stocks without orders. Otherwise, there is a possibility that waste copper waste aluminum will be wasted. . Secondly, it is necessary to pay attention to aluminum wire and copper wire. Copper and aluminum are very soft, and aluminum chips are very likely to stick in the mold cavity to cause scratches. The aluminum material is best able to put on its surface for an oxide film. This reduces the chance of sticking. In addition, it is necessary to spray (solid, powdery, and) lubricants on the surface of the aluminum during production to minimize stick-die phenomena. In the end, no matter how hard you try, it can't be guaranteed completely, so you can only look at the production of one machine at a time. When sticking, you can stop and remove the aluminum chips and start production again.
