• The raw material used in this project included: Carbon steel, stainless steel, Copper etc. It processed with EDM wire cutting, lathe, CNC milling, drilling, tapping, welding and final assembly.


  • The copper terminal is a piece of metal sealed inside the insulating plastic. One end or both ends have holes for inserting the wires, and some are used for fastening or loosening by screws, such as two wires, sometimes need to be connected, and sometimes need to be disconnected. At this point, you can connect them with the terminals and disconnect them at any time without having to solder them or entangle them, which is convenient and quick.


  • What is the reason why the aluminum profile is light and black when it is black at normal temperature? How to deal with it? - Ningbo Paiyan Precision Machinery Co., Ltd ​The reason: 1 black time short profile oxidation, residue on the parts; 2 solution acidity is low; 3 The composition of the solution is out of proportion.

  • Wire Electrical Discharge Machining (WEDM) is a category of electrical processing. It was discovered by the former Soviet Union Lazardenko couple that the switch contacts were damaged by spark discharge corrosion and found that the instantaneous high temperature of the spark can be The local metal is melted, oxidized, and etched away, thereby inventing and inventing the electric discharge machining method. The wire cutter was also invented in the former Soviet Union in 1960, and China was the first country to use industrial production.
