The definition of a wire drawing die is a die where the metal is forced to pass under the condition of an external force, so that the cross-sectional area and shape of the metal can reach the specified format, that is to say, the tool that helps the metal to form a specified shape in the metal pressure processing of the wire drawing die. In other words, the wire drawing die is also a die that changes the thickness of the metal wire to achieve the required size. The core of the drawing die is generally made of three materials, one is natural diamond, and the other is man-made diamond, which is applied to copper wire material. Of course, there is also a commonly used wire drawing die, which is a hard wire drawing die. The copper wire drawing die is also called a soft wire drawing die. The general compression zone angle of the copper wire drawing die is about 20 degrees, and the fixed diameter length is about 30%, while the general compression zone angle of the hard wire drawing die is only about 13 degrees, and the fixed diameter length can only reach 100 degrees. About fifteenths. The wire drawing dies also include diamond wire drawing dies, cemented carbide wire drawing dies, plastic wire drawing dies, etc. There are many categories.
