Carbide drawing dies usually refers to the various metal wire drawing die, as well as the optical fiber drawing die. All drawing dies have a hole in the center of a certain shape, round, square, octagonal or some other special shape. The metal becomes smaller and even changes shape as it is pulled through the die hole. A steel die is sufficient to stretch a soft metal, such as gold and silver. The die may have several holes with different diameters. Drawing die widely used, such as electronics, radar, and TV, instruments and high precision wire and used in the aerospace and other commonly used tungsten, molybdenum wire, stainless steel wire, electric wire and cable wire and all kinds of alloy wire.
Attensions for mold use
1. The mold shape and size suitable for the material to be stretched must be selected, otherwise it will be easy to produce mold crack damage;
2. The mold must be fastened correctly along the stretching direction, without deviation to prevent uneven wear;
3, lubricant has a great influence on the life of the mold, choose the appropriate lubricant and keep the mold in a clean state;
4. Do not knock or throw the mold.
