Learning of PCD DRAWING DIES

A PCD (Polycrystalline Diamond) drawing die, also known as a diamond drawing die, is a specialized tool used in the wire drawing process to reduce the diameter of wire or rod. It is commonly used in industries such as manufacturing, electrical wiring, and cable production.

PCD drawing dies are made from synthetic diamond materials, which are extremely hard and wear-resistant. The diamond material is typically sintered or bonded to a tungsten carbide or steel substrate to form the drawing die.

Here's an overview of how a PCD drawing die works:

Wire Insertion: The wire or rod to be drawn is inserted through the entry hole of the drawing die.

Drawing Process: The wire is pulled through the drawing die by a drawing machine or equipment. As the wire passes through the die, the diameter of the wire is reduced gradually.

Die Design and Construction: PCD drawing dies are designed with a specific hole size and shape to achieve the desired wire diameter reduction. The die is precision-engineered with a smooth and highly polished internal surface to minimize friction and ensure accurate wire dimensions.

Diamond Properties: The PCD material used in the drawing die is chosen for its exceptional hardness, wear resistance, and thermal conductivity. These properties allow the diamond drawing die to withstand the high pressures and friction generated during the drawing process without significant wear or deformation.

Lubrication and Cooling: To minimize heat and friction, lubricants or coolants are often used during the wire drawing process. This helps to reduce wear on the drawing die and maintain the quality of the drawn wire.

Wire Exit and Finished Product: The drawn wire exits the drawing die and can be further processed or used as a finished product, depending on the application.

PCD drawing dies offer several advantages over traditional drawing dies made from other materials. The exceptional hardness and wear resistance of diamond enable longer die life and reduced downtime for die replacement. Additionally, diamond drawing dies can produce wires with precise diameters, smooth surfaces, and excellent dimensional accuracy.

It's worth noting that the design and specifications of PCD drawing dies can vary depending on the specific application and wire drawing requirements. Manufacturers may offer a range of die sizes and shapes to accommodate different wire types and sizes.

Types of Wire Drawing Die:

1 PCD/ND Wire Drawing Die:Diamond dies are widely applied to a variety of industries, implemented as drawing tools for soft wire products (copper and aluminum wire), as well as hard wire products (stainless steel, tungsten and copper plated steel wire).
2 PCD DIE:Polycrystalline is a kind of synthetic material which combines the advantages of perfect surface finish, minimum friction and high wear resistance. Application:Nonferrous wire, including copper, aluminum, electromagnetic wire and stainless steel.

3 ND DIE: It is formed by natural crystal which is single crystal without grains Diamond of such mold holed are especially easy to be gained smooth face, easy to be extruded with high speed. The life of drawing wire is been increased, also decrease the risks of unfasten. split.

Application:Platinum rhodium wire, gold wire, silver wire, copper, aluminum, molybdenum, nickel, copper, tungsten, copper aluminum alloy and other nonferrous metal wire material.

Notice

Carbide wire drawing dies usually need to pay attention to five points of attention when using, equipment selection, pretreatment of wire materials, selection of appropriate lubricants, abnormal handling, and timely replacement of aging;

1. Equipment selection: According to the material you want to draw and the wire drawing equipment, the compression ratio of each wire drawing die is reasonably matched to determine the angle of the working area of each wire drawing die. (that is, what type of drawing die to use)

2. Pretreatment of wire drawing materials: such as cleaning, rust removal, annealing, phosphating, etc., to ensure the cleanliness of the material.

3. Drawing powder and oil selection: choose high-quality and applicable drawing powder (lubricant, oil), and do a good job of cooling the drawing die.

4. Deal with abnormal molds in time: If there are mold cracking, mold explosion, mold sticking, wire cutting, diameter reduction, broken wire, high temperature, mold blackening, non-wear resistance and other use problems during wire drawing, please contact professional and technical personnel in time .

5. Timely replacement of aging wire drawing dies: When the wire drawing die reaches its service life, please replace the wire drawing die in time to repair the die, so as to avoid the excessive use of the wire drawing die and cause the wire drawing material to be scrapped.
