We have always believed in providing our customers the complete management solution for their cutting needs. In the light of this we have always upgraded ourselves with the latest technology and state of the art manufacturing facilities. wIth this principle in mind we have developed and introduced tungsten carbide knives for the paper industry.

We are confident that with this introduction along with our long standing idea of providing the highest quality knives at competitive pricing people more in the paper industry will start using such knives in future.

Why tungsten carbide knives: They are preferred over other knives in modern paper industry due the fact that tungsten carbide is a highly wear resistant material and is very stable which means that tungsten carbide knives have a very long lifetime.

» Tungsten Carbide Guillotine Knives, Trimmer Knives

They offer the following important advantages :
¤ Less machine down time
¤ Mainimum material loss during regrinding
¤ High and long lasting cutting quality
¤ Stability in cutting edge
¤ High productivity
¤ Low per unit cost

A very high speed operations the wear on circular knives is a familiar phinomenon. Anging them frequently causes loss of production and quality. The solution for this is tungsten carbide circular knives because the edges of tungsten carbide knife stay sharp much longer.

In the modern paper industry the needs of any manufacturers include high speed production, high precision cutting with longer life of knives. Atlas tungsten carbide sheet cutter knives are the perfect solution for their needs.

Tungsten Carbide guillotine knives. Trimmer knives are available for all types of machines with shortest delivery periods. Tungsten carbide knives ensures clean burr free cutting, high productivity with long standing razor sharp edges & high quality finish. They are ideally suited for high speed production, quality printing & packaging jobs.

We have always believed in providing our customers the complete management solutions for their cutting needs. In the light of this we have always upgraded ourselves with the latest technology in the world. With this principle in mind we have introduced Powder Metallurgy knives.

D.B. Engineering Private Limited is the first company to introduce powder metallurgy knives in India. Powder Metallurgy knives are now popular worldwide and are mainly used by leading Paper industries. However they can be used for other industries as well for special applications.

Advantage of Powder Metallurgy over Conventional Steel Making process:

In the conventional steel making process all the time we encounter with the following detrimental aspects in steel-
A) Presence of impurities viz sulphar and phosphorous in steel due to their chemical equilibrium characteristics with other elements present in steel with the ultimate result of poor toughness and poor interactive binding strength in steel causing poor quality tools.

B) Non-uniform distribution of alloys both no carbide forming and carbide-forming types adversely affect the toughness and abrasion resistance properties of tools. This type of non-uniform distribution of alloy is often termed as segregation and is caused due to sluggish diffusion rate of alloys during solidification of molten steel and the same is not completely removed in subsequent hot working process.

It is always to be remembered that introduction of powder metallurgy has been done to avoid the major defects as mentioned above. In this method first molten steel is allowed to percolate through a premixed slag cover which acts as a trap for subpart and phosphorous thus making the steel free from these two elements subsequently sulphar and phosphorous is atomized in the presence of inert gas like nitrogen. Due to this atomization alloys do not get any chances to segregate. As a result we get a very pure and uniform in composition which is given suitable shape by hot isostatic pressing forging and rolling process.

High purity and uniformity of composition, which causes uniform grain size, Uniform distribution of alloy carbides causing tremendous up gradation of tool standard due to high impact strength, improved bending strength, High abrasion resistance and superb toughness.
