Amongst the various Wire Drawing Dies, the tube drawing process is slowly gaining demand due to its specific uses in certain modern industries. Tube drawing is used in several applications like diesel fuel lines, aircraft hydraulic lines, semiconductor manufacturing, chromatography, thermocouple sheathing, and other industries. Generally, tubular products need close dimensional control and smooth and ultraclean ID surfaces. It depends heavily upon the perfect drawing process, and therefore the Tube drawing Dies should be of high quality and have excellent finishing. 

Tube manufacturers often use tube drawing with the help of superior dies to change the tube IDs, ODs, and wall thickness. It is also seen that drawing improves the surface finish even more and refines the grain structure.

Tube Drawing and Other Dies

In tube drawing, the most used die is the sintered tungsten carbide. The tungsten carbide is also encased in steel, and the cobalt content is 10% approximately. The higher the cobalt content, the better the shock resistance, while a lower cobalt percentage would mean that the die has good wear resistance. 

Tube sinking is drawing the tube through a die to reduce the outer diameter and the insider diameter of the product. Sinking is the least expensive of the drawing methods and can save a lot of money for enterprises. But unlike the diamond drawing dies, excessive sinking, in this case, can have an adverse effect on the surface quality. Although more expensive and used only for specific drawings, these dies are fabricated via CVD and have great performance. 

The diamond dies are highly-polished products and have shaped holes through which wire passes. The dies have a metal case and a nib made of tungsten carbide polycrystalline diamond. The pcd wire drawing dies have brought forth a small revolution in the area of dies and are currently in most demand. PCD is made by sintering micron-sized diamond particles and binders under high temperature and pressure. Despite long life and uniform wear, they are unsuitable as Dies for tube and pipe drawing but are the best for certain other unique industries. Besides, they are also expensive. 

Tube and Rod Drawings

It is generally seen that tube manufacturers use rod drawing when the sizes are unsuitable for plug drawing. It is especially seen with a heavy wall or small ID tubing, which is not like dies for drawing wire as is generally seen.  It also requires lesser setup time, and therefore you can rely on small runs. Hence, tubing of very high pressure and heavy-wall hydraulic tubing is produced by rod drawing, and a sinking operation follows it to create finished dimensions. 

If you wish to purchase drawing dies for your enterprise, then you should choose wisely. Only the best wire drawing dies manufacturers can deliver you top-quality products priced lower than other competitors.
