Applications of Tungsten Carbide Drawing Dies

Tungsten Carbide Drawing Die has a wide range of uses, such as electronic devices, radar, television, instrumentation, and aerospace and other high-precision wire and commonly used tungsten wire, molybdenum wire, stainless steel wire, alloy wire and cable wire. A variety of diamond wire drawing dies are pulled out for use. Diamond wire drawing die use natural diamond used as the raw material, which has strong wear resistance, high service life.

Types of Tungsten Carbide Drawing Dies

1.Steel die. There can be a number of different diameter holes on steel die.
2.Carbide Die - used for drawing wire (steel wire).
3.Wire mode - used to pull non-ferrous metal wire, such as copper, aluminum, etc..
4.Polycrystalline module - used to pull thin polycrystalline module (Artificial Diamond), and use of natural diamond drawing die.


What is Tungsten Carbide Drawing Dies?

Tungsten carbide drawing dies usually refers to all kinds of wire drawing die, there are pull-mode optical fiber drawing. The center of all the drawing die hole has a certain shape, round, square, octagonal or other special shapes. Metal is pulled through the die hole size smaller, or even shape change.

Main Properties of Tungsten Carbide

Tungsten Carbide Properties:

Excellent Hardness: 86~93 HRA, which equal to 68~81HRC;
Excellent hot working performance: Hardness could be remained at 60 HRC under 900~1000 ℃
Excellent wear resistance;
High cutting speed;
Long service life;

Tungsten cemented carbide

Tungsten cemented carbide is the preferred material for parts that must withstand all forms of wear (including sliding abrasion, erosion, corrosion/wear and metal-to-metal galling) and exhibit a high degree of toughness. It exhibits high compressive strength, resists deflection, and retains its hardness values at high temperatures, a physical property especially useful in metal-cutting applications. It provides long life in applications where other materials would not last or would fail prematurely.

Characteristics of Carbide Cutting Tools

Making use of sophisticated technology in manufacturing process has made these cutting tools durable, ant-corrosive and dimensionally accurate. These are highly durable and have excellent cutting edge quality that ensures optimum performance. Further, these are also temperature resistant and provide. 

Understanding various requirements or drawings of our clients, we design carbdie cutting tools in different specifications.

How Cemented Carbides are Made

Carbides are made by blending micron-sized tungsten carbide and cobalt powders, then compacting the mixture in a mold and sintering the molded part at a temperature high enough to cause the cobalt to flow. During this process the cobalt fills the voids between the tungsten grains and thoroughly coats each grain. When the cobalt solidifies, it cements; the grains together, forming a dense composit. Cemented carbides get their hardness from the tungsten grains and their toughness from the tight bonds produced by the cementing action of the cobalt metal. By varying the amount of cobalt we can change the hardness, wear resistance and toughness (shock resistance) of the carbide to suit your particular Tungsten Carbide needs.

The analysis of the tungsten carbide bearing wear

In general,tungsten carbide bearing can be allowed to reach the longest bearing service life if it is in proper use.But there will always be accidental damage. It is because of the careless installation of the bearing, the pay no attention to the intrusion of foreign bodies from the outside,etc.

The Advantage of Tungsten Carbide Stud Pins

Tungsten carbide stud pins offer a dramatic increase in traction on hard-packed trails and ice and reduce the spinning of the track under aggressive acceleration, decrease the likelihood of getting stuck and allow tighter turns and skid-free stops. They allow a snowmobile to climb hills that were previously impossible to climb. Control of the snowmobile is increased and riding is safer. Tungsten carbide stud pins offer an opportunity to significantly increase riding enjoyment and performance of snowmobile.
All of our materials for the tungsten carbide stud pins are made from virgin raw materials and according to ISO standard, thus results in trusted quality with favorable prices of products.

Tungsten Carbide Punch Pins

Tungsten carbide punch pins are more slender and each punch pins is produced to the highs of critical tolerance for maximum tool life while accuracy and repeatability in production ensures that each punch pins offer predictable performance. These tungsten carbide punch pins are best examples of durability, sturdiness, long service life and corrosion resistance. Renowned for its tensile strength, they come in wide variety of grades and sizes. Well able to withstand any quality testing, these are in high demand in international market.

Processing Craft of Tungsten Carbide Nozzles

Tungsten carbide have high hardness, low toughness and poor process, and therefore it was not suitable for production of complex structure nozzles. In practical applications, people usually made ​​of hardness tungsten carbide ring or block inlay at the nozzle's some serious wear parts. But some will inlaid the tungsten carbide on the fraggile parts of nozzle, such as the United States, Canada and other countries' Y-type nozzle and Chinese multi-stage nozzle.

The Advantage of Tungsten Carbide Nozzle

The manufacturing process of tungsten carbide nozzle is much more complex then metal nozzle. Therefore the cost will be relatively high, but have a longer service life under the same conditions. Since tungsten carbide have the higher strength and toughness, and also good thermal conductivity, so it has a higher hardness then metal material and the erision rate is much smaller then metal nozzles, the anti-erosion performance will be better then metal nozzle.

The Applications of Tungsten Carbide Nozzles

Tungsten carbide nozzles are mainly used in chemical, food, machinery, metallurgy, construction industry, milling, rust removal, cleaning, fog and so on. It has over 800 kinds of specifications, which was the first choice for dusting decontamination of cement and other operating environmental dust pollution manufacturers. Use for oil-fired boiler fuel furnace, industrial furnaces and other special-purpose furnace and so on.

Making the Tungsten Carbide Raw Material

When a mixture of powdered tungsten metal and carbon powder are raised to a very high temperature by an arc of electricity, while the whole mass is held in a carbon crucible, there is a complete chemical combination of the two elements to form a big lump of tungsten carbide ( WC ). This lump is crushed several times and then milled to form a fine powder. The powder is screened down to uniform particle sizes.
