There are different types of Wire Drawing Dies available in the market. Tube drawing method is gaining demand slowly the world over. This is because it is being used specifically in some modern industries. Several applications do witness using of Tube drawing method like aircraft hydraulic lines, diesel fuel lines, chromatography, semiconductor manufacturing, thermocouple sheathing along with other industries.
About Tubular products
Tubular products generally require close dimensional control, smooth as well as ultraclean ID surfaces. This again heavily depends on perfect drawing procedure. It is for this reason, Tube drawing Dies that you plan to buy needs to be of superior quality. Also, it should boast of having excellent finishing.
Often, tube drawing is used by tube manufacturers using superior dies. The objective here is to change completely the tube’s ODs and Ids as well as wall thickness. Drawing also helps enhance surface finish while refining grain structure. More information can be derived at the top portals on quality dies. It also includes dies, tube, etc. along with those products that you can plan to buy for specific purposes.
Other essential aspects
When tubes drawing are concerned, sintered tungsten carbide is regarded to be the most used one. Tungsten carbide is encased within steel while cobalt content is stated to be about 10%. Higher cobalt content means enhanced shock resistance. On the other hand, lower cobalt percentage will mean good wear resistance of the die.
Tube sinking can be termed to be drawing the tube via the die. The purpose here is to diminish the product’s internal and external diameter. The least expensive among the lot is sinking as it can help save a good amount of money for businesses. However, unlike that of diamond drawing dies, sinking excessively will only have adverse effects upon surface quality. It is quite expensive and hence, used for specific drawings only. Such dies are usually fabricated using CVD while assures enhanced performance.
Diamond dies can be termed to be highly polished products. They do have shaped holes via which wires are passed. Such dies for drawing wire come with a metal case along with a nib created from tungsten carbide polycrystalline diamond. PCD die types are credited with having revolutionized the die area and hence, growing in demand. PCD is generally created by sintering binders and diamond particles of micron sized. This is achieved under extreme pressure and temperature. Since it has uniform wear and long life, it is found to be unsuitable especially as Dies for tube and pipe drawing dies. However, for other industries, it is found to be quite favourable. They are also stated to be quite expensive.
Rod and Tube Drawings
Generally, it is noticed that rod drawing is used by tube manufacturers if sizes are found to be unsuitable especially for plug drawing. Generally, it is noticed with small ID tubing or a heavy wall, something drawing wire dies. Moreover, it requires less setup time. Hence, you may rely upon the small runs. Tubing under extremely high pressure as well as heavy wall hydraulic tubing gets created by rod drawing. Then follows a sinking operation to produce finished dimensions!
