Shree Radhekrishna Extrusions Pvt. Ltd. has grown to become the largest manufacturer of Screw and Barrel for Plastic Processing Machinery in India with skill employees and state-of-the-art production center.
At this center, a wide range of Plastic Processing Machinery spares and High speed heater cooler mixers and spares are manufactured in house facility to maintain the highest standards of accuracy all along the way.
It is our great pleasure to explain you about our infrastructure. We would like to appraise you that Radhekrishna is the first organization in screw & barrel manufacturing who invested too much in machineries. We have a lot of machineries for screw & barrel manufacturing.
We are also aware that in the screw & barrel, the accuracy is the biggest factor which can affect the quality. If we have to make a good quality then we must have the all machineries at one place. Radhekrishna is one and only who have these all & more than enough machineries for manufacturing the screw & barrel.
We have all CNC & DRO based machineries for screw & barrel manufacturing. Even though we have in house Nitriding furnace too. We can say that you can keep blind trust on Radhekrishna for accuracy and all.
These Thread Milling Machines are fabricated in accordance with the Screw Manufacturing standards and norms using optimum quality raw material & advanced technology.
The deep-hole drilling machines is used for Making a hole in Barrel and gundrilling which delivers the power we need to machine even the toughest materials with precision and reliability. This machine applies power intelligently, allowing us to drill more accurately and with less risk of damage to your tooling or your work piece.
Gun drilling is a process that produces deep, straight holes in a variety of materials. A gundrill tool differs from a conventional twist drill by its unique head geometry; a standard gundrill has a single effective cutting edge. Guide pads burnish the hole while drilling, allowing the hole to maintain straightness. The result of this burnishing activity is a very round hole with a precision diameter. So it can be used to make a hole in the screw for coolant & make a hole in the barrel too.
Very versatile for machining big and small pieces , constant power at all RPM ranges Very high efficiency production Excellent quality finish of the machine pieces , maximum precision, perfect accuracy
We have our own nitriding furnace, it is the biggest benefit of us, normally others do nitriding process – total cycle time 96 hrs – 8hrs purging time (with ammonia gas passed through the furnace & inside atmosphere with totally ammonia gas& temperature achieve 530ᵒc) + soaking time 72 hrs. (With 530ᵒc & ammonia gas pressure maintain) + 16 hrs. Cooling time up to 150ᵒc, but we are maintaining soaking time 80 hrs. Instead of 72hrs to get better nitriding hardness & case depth. We maintain 0.5mm in-depth layer of 64 to 68 HRC in Screw & Barrel.
Our All DRO Based Machines are having complete DRO system, including magnetic tape and reader heads for angular measurements on large rotary tables. Typically, these rotary tables are part of horizontal boring machines and other such machines.
Angular rotation of the table during machining needs precise measurement. This particular need is not completely fulfilled by optical rotary encoder coupled to the table center. Where this system proves useful. Table diameters starting from 300mm are supported and max diameter can be as large as 10meters.
The machine is widely used in engineering and other industries for manufacturing various components, we use to do the Vent Operation and Hopper Operation on this machine. It provides perfect accuracy in all parameters.
We have 2 nos of Hi Tech Grinding Machine which gives the perfect and smooth surface on the screw and barrel.
This machine is used to polish soiled or rusty screw of all kinds, or for the removal of cold welds.
The press can efficiently handle round, flat and profile material of different hardnesses. Our hydraulic straightening presses have a compact design with easy stroke control operation. These presses are equipped with all the advanced features and provide great flexibility in operation. Available in either C-frame presses or Gantry style presses, hydraulic straightening presses are mainly used for straightening medium or thick sheet, section, tube or round bar.
We are using extra heavy duty lathe machine for perfectness in accuracy. This machine is mostly used for turning operation, barrel’s OD turning, Screw material turning. It boosts the production of Screw Barrel Grooved Sleeve and flanges.
We use this machine to make a hole on flanges.
Drilling is a cutting process that uses a drill bit to cut or enlarge a hole of circular cross-section in solid materials. The drill bit is a rotary cutting tool, often multipoint. The bit is pressed against the work piece and rotated at rates from hundreds to thousands of revolutions per minute.
We have in house facility for tungsten carbide coating. We use standard L&T made rod for Tungsten Carbide Coating. It provides batter life in comparison to powder coating and any other coating.
Hobbing is a machining process for cutting splines on a hobbing machine, which is a special type of milling machine. The teeth or splines are progressively cut into the workpiece by a series of cuts made by a cutting tool called a hob.
