Die Manufacturing

Die Manufacturing

Our manufacturing process includes precision machining, thread milling & slotting operation, accurate deep-hole drilling for high quality hole finish, Inverted countering and outer relieving operation, vacuum heat-treatment under fully temperature controlled furnace and finally high quality grinding to facilitate excellent fitment.

Our complete range includes Dies of holes as small as 1.4mm & upto 12mm holes.

Our D-CHROME and D-CARB dies guarantee

  • Higher production
  • Increased rate of production per hour
  • Substantial reduction in the power cost
  • Unaffected by hot steam, molasses and other fat contents
  • Easy pelleting right from the start
  • Minimizing the maintenance time
  • Negligible hole enlargement

Carb Rollers

  • Corrugated rolls close/open end
  • Dimple rolls
  • Helical fluted rolls
  • Pinnacle close end rolls

Carb rolls are hardened to 60-62 HRC to provide long service life and are compatible to all types of dies.

Carb Rollers Leading Manufacturer and Exporter from Halol, our product range includes New Items such as Pellet Mill Dies - D Carb, Vibro Sieve and Gyro Sieve.

Pellet Mill Dies - D Carb

After successful launch and acceptance of D-Chrome™ world wide RK has launched a value added product D-CARB. These are the dies used mainly for Cattle feed and for high roughage wood/Bio-Fuel Pelleting. These dies are available with hole dia 4- 12mm.

It has the salient features..

  • Corrugated rolls close/open end
  • Dimple rolls
  • Helical fluted rolls
  • Pinnacle close end rolls
  • HIGHER PRODUCTION than the conventional alloy steel dies ( nearly 1.5--2.0 times the normal production );
  • Increased rate of production per hour ( nearly 10%-20% increase in tonnage / hour )
  • Substantial reduction in the POWER COST ( nearly 7% - 10% reduction in power bill per month);
  • Unaffected by hot steam, molasses and other fat contents in the feed due to HIGHER SURFACE HARDNESS ( Hence less rusting, thereby minimizing wearing of the die)
  • Easy pelleting right from the start ( minimum surface friction, NO JAMMING due to highly polished holes );
  • SLOW WEAR OUT ( due to the composition of the raw material and higher surface hardness achieved);
  • Minimizing the maintenance time
  • HOLE ENLARGEMENT after 70-80% of the die life, which facilities even pellet size through out the die life.

It has all the advantages of Gun drilling – mirror polished hole surface, equally distributed holes which leads to better performance, high life and least breakage in dies. There are the dies made for high fibre,hi-roughage & difficult to pelletized formulations .


Spares - Pellet Dies And Rolls
Spares are the lifeblood of any feed plant and that is why we always endeavour to go out of our way to service any feed plant annually or on emergency basis. Pellet Mill Dies - D Chrome
We have the delight to share with you that the manufacturing of Gun Drilled Dies at our Halol plant has now completed almost 15 years of operation catering to the varied requirement of domestic and international market.
We have the pleasure of informing you that the CNC based GUNDRILLLING MACHINES are specially designed for drilling of smaller as well as large hole diameter pellet dies (1.4mm-12mm ) which has been a major breakthrough working for the Indian pelleting industry. All over the world CHROME DIES / STAINLESS STEEL DIES are most demanded because of its hole finish and durability. CHROME dies facilitates not only in higher rate of production, but also in excellent gelatinisation that is never possible with ALLOY STEEL dies.
We are also delighted to inform you that presently we are working for almost all major feed millers in India and EXPORTS to NEPAL, SRILANKA, BANGLADESH, SOUTH AFRICA, EGYPT, ITALY, RUSSIA, UAE, THAILAND, TURKIYE, SYRIA and many more...
We are pleased to inform you that now you can fully depend on R K Machines for the GUNDRILLED CHROME DIES and we assure you that with advanced planning we will be able to provide D-CHROME Dies in 4/6weeks. We have the pleasure of inform you that we are the only manufacturer in the country as on today who have ventured into the manufacturing of GUNDRILLED CHROME DIES duly vacuum hardened in computer controlled furnace and are guaranteed for very high tonnage. We have the delight to inform you that all over the world gun drilling being the ultimate technology in the manufacturing of smaller hole pellet dies, for poultry as well as for the aqua feed pelleting ( dia 1.4mm to 5mm maximum ) and we are fortunate to have the identical world class facility at our Halol works.
Our dies are made from proven German grade chrome steel and are gun drilled for mirror finish holes and vacuum hardened in world class sophisticated furnace to provide the best hardening strength for long hours operation.
We have coined a trade name for the Gun Drilled Chrome Dies as D-CHROME™. We are proud for our Global presence with D-CHROME™ dies. The salient features may be noted as under.

  • Precision machining, cutting and milling operation.
  • Accurate deep hole drilling for high quality hole finish.
  • Countering and reliving operation
  • Vacuum heat treatment under fully temperature controlled furnace
  • Finally, high quality grinding to facilitate excellent fitment.
