A tool used for metal press working compels the metal to pass via a die under external force. This, in turn, compresses the metal cross-sectional region, thus obtaining the size and shape of the desired cross-sectional area. It is referred to as a draw die. Generally, Wire Drawing Dies are used like high-precision wire materials in radar, electronic devices, aerospace, instrumentation, television, etc. The commonly used ones are molybdenum wire, tungsten wire, cable wire, stainless steel wire including different alloy wires.

The diamond drawing dies is said to pull these wires. The raw material used here to create the wire die is naturally found diamond. It is known for its high service life and strong wear resistance.

Production process

The drawing die production procedure generally includes numerous steps like draft drawing, die pressing, and turning. Drawing die can be termed to be a wire that is sent through a mold with the objective to make it fine from being coarse. It then gradually takes the desired size. This special die type is considered to be the drawing die. It is made from synthetic diamonds or natural diamonds. On the other hand, a copper wire die is considered to be a soft wire die. With some research, you may also come across hard wire dies like tungsten drawing dies, pull tungsten wire, etc. So the compression zone angle can be stated to be relatively small about 12 to 14 degrees.

According to the experts at, drawing dies tends to include hard alloy dies, diamond drawing dies, plastic drawing dies, etc. Usually, drawing die refers to different kinds of metal drawing molds and pull fiber dies. Drawing dies, in general, has a center with a certain hole shape that can be octagonal, square, round, or of other special shapes. On pulling the metal via the die hole, the size becomes much smaller while there are chances of it changing in shape. Soft metal like silver or gold can be pulled by a steel mold. The plurality of holes may be present of different diameters within the steel mold. Well-established wire drawing dies manufacturers offer drawing dies that are used mostly in various high precision wire materials. It includes radar, electronic devices, aerospace, instrumentation, and television.

Cemented Carbide Dies

To draw steel wires, tungsten carbide nibs generally are used. Such dies’ typical structure is somewhat cylindrical in shape. The ground is also embedded within the circular steel case having an Entrance angel, Bell radius, Bearing, Approach angle, etc.

Steel wire mold

In this type, pull non-ferrous metal wire-like aluminum, copper is quite similar to that of diamond dies. The hole shape is somewhat different.

Polycrystalline silicon mold

A polycrystalline diamond may use a pull thin line including a natural diamond die. For the core, carbide wire die tends to adopt superior quality hard alloy, exhibiting a small friction coefficient, excellent thermal conductivity, and high hardness.

The Carbide wire die is considered to be simple to produce, has strong impact resistance, corrosion resistance, and comes with a low price. It is these aspects that make carbide wire die and Diamond Drawing Dies quite popular among select industries.
