4 PRINCIPAL FIELDS OF APPLICATION PRINCIPAL : PVC Resin is Heat sensitive Material and can not extrude alone. PVC Resin need to be mixed with stabilizer and lubricants with filler. Stabilizer will improve the heat stability to PVC Resin and Lubricants improve flow properties of Pvc Resin with addition of filler it will give strengthen to end product as PVC Resin is polar material. With High speed mixer mixing will take place with all ingredients at certain speed, where Shear will take place. While mixing at high speed PVC Resin will shear in between bottom arc of vessel and Shear Blaed. As the heat generate PVC Resin Bulk density is improve and particle size too. Which will help to absorb additive. The compound need to be mix up to 80degree to 125 degree centigrade temperature to absorb additives in totality. We learn from above process with high speed mixture that compound mixed will need to be cool down to remove statics created due to shear of material as well as to normalize particle size of Pvc Resin. APPLICATION PVC Resin compounding Rigid and Soft Application. Color Master batch compounding. Calcium carbonate coating application. Rubber Industries. Textile bleaching compound application. Hydroscopic material mixing application. Paint & Coating Industries. Wet Coating, Ceramics, Dyes and Colours, Pharmaceuticals and other allied industries.

5 Why Radhekrishna High Speed Mixer Require for PVC Resin? Advantage of Radhekrishna Mixer: Maximum production with economical operation at Low power Consumption as low as 25Paise/Kg(approx.) at versatile filler loading and without cross contamination. Economical operation with less labor cost with Atomization. Lower scrap rates in the extrusion lines due to the best mixing with dry blend quality. Even with high filer loading Maximum 05 batches/hour. Excellent improvement of resin bulk density to absorption additives before Filler as it is hydroscopic nature as well as Mixing with filler. Adequate designed with precise tolerances ( 4 Axis ) ofbottom Arc to Shear Blade for faster rate of heat temperature as well as of Mixing Blade for faster and unique mixing. Zero wastage of compound due to decomposition of compound due to moisture. Perfect positioning of Temperature Sensor for unique compound mixing.

20 NEW TECHNOLOGY Founded By 1.Screw Pair - First Zone Will Be Tungsten Carbide Coated : We think you are also aware that the First Zone(Melting Zone) takes higher or more load in the comparison of other zone, so that's why we are coating of Tungsten Carbide on surface of same zone so it will give you better life against higher filler loading & other particles. 2. Front Barrel will be HSS Sleeve Fitted : For Same reason, we provide sleeve on front barrel ( which will be fitted on Melting Zone), Which made from "High Speed Steel", it also give better life against wear & tear. After Many years of experience & research & development, we have found new technology, which we have described below :

21 Screw & Barrel made out of EN -41B (Moscow make steel),Nitride steel. The material is T conditioned by thermal process. Screw profile is done on thread milling machine. Honing of barrel is done to achieve superior internal bore surface finish. Screw is highly polished by special purpose polishing machine. Stabilizing is done to remove all stresses developed. Screw & Barrel is nitride harden,skin hardness maintain 68 to 70 HRC. Nitrided layer thickness maintained up to 0.47 to 0.50 Screw will be straight with in 0.07 m. m. on turn over by hydraulic press. Close clearance and exacting machining tolerance for screw and barrel. All the procedures are done under Strict Quality Control Screw & Barrel made out of EN -41B (Moscow make steel),Nitride steel.

Close clearance and exacting machining tolerance for screw and barrel. All the procedures are done under Strict Quality Control Glimpse of Process for Screw & Barrel

22 Procedure of Screw Raw Material – (We are using EN-41B (Moscow-Steel) Material.) Chemical Analysis – (We are using EN-41B Material but it is Original composition or not, to check we do a test for it.) Gun Drill – ( It is mainly used to check that Screw is Straight or not. Secondly it is also used for water cooling & drilling in barrel.)

23 Procedure of Screw Toughening – (When we use Raw material it has uneven hardness so to maintain its hardness this process is used.) Blank Operation – (It is used for Pre – Stage machining for zone wise flight cutting) Spline Cutting – (As per Gear Box Spline Screw is used to Spline for Windsor and Kolsite Design.)

24 Procedure of Screw Flight Cutting – (There are two options for Flight cutting) 1. We can cut it on CNC Machine 2. We can manually cut it on Thread Milling Machine. Inspection By us – (We check that everything is O.K or not.) Thread Milling Machine CNC Machine

25 Stabilizing Operation – (If there are Un-Even Stress or Scratches on Screw, these process is used to remove that.) Polishing – (This process is used to polish the Outer Diameter which we keep.) Grinding – It is used to maintain Final Size and for Finishing. Procedure of Screw

26 Inspection – (We check that every thing is done in proper way or not until previous process.) Gas Nitriding – (It is used to maintain hardness of Screw.) Straightening – (When the screw comes from Nitriding it is not straight as before so this process is used to Straighten the screw) Procedure of Screw

27 Inspection – (In this inspection it is checked that Screw has maintained the hardness of 65 to 68 HRC or not and 0.4 to 0.5 Deep) Final Grinding – It is used to maintain final Size & Finishing. Buffing & Polishing – It is used to completely polish the screw and give a new look to it. Metal Hardness Tester

28 Procedure of Barrel Cutting : First of all we are cutting the bars & make the Proper length of barrel. Rough Bore – (This Process is used to make bore on Deep Gun drill Machine.) Tuffning - (When we use Raw material it has uneven hardness so to maintain its hardness this process is used.)

29 Procedure of Barrel Final Bore – (In this Process we can get Final Size of Bore.) Thread Cutting – It is used to cut Flanges. Primary Inspection.(With the help of Bore Gauge & Micrometer we are measure the Bore of Barrel & Outer Diameter.)

30 Procedure of Barrel Honing – (This Process is used to achieve complete Mirror Finishing, If we put our fingers on barrels than our fingers also Slide.) Secondary Inspection - With this process we are Inspecting bore & Center Distance of barrel that Every thing is ok or not) Hopper Mounting Cutting & Vent Cutting – (This process is used for material feeding and Vent Cutting)

31 Procedure of Barrel Dowelling – (This process is used to match Gear-Box Side Flange with, Barrel’s Flange and if it is Twin Barrel than it is necessary to match Front & Rear Barrel.) ↓ Drilling Operation – (This process is used to pierce hole in Thermocouple.) ↓ Nitriding – (It is used to maintain hardness of Barrel.) We have our own Nitriding furnace at our work place.

32 ↓ Third Inspection ↓ Polishing – (This process is used for polishing barrel to get proper finishing.) ↓ Matching – (In this process it is checked that screw is running properly, in Barrel or not {Free Rotation}.) ↓ Final Inspection – (After finishing all operations final inspection is done.) Procedure of Barrel

33 POINTS WILL ENCOURAGE YOU TO WORK WITH POINT: 1 – WE ARE PURCHASING EN-41-B FROM M/S GIRDHARILAL AGRAWAL: Actually M/S GIRDHARILAL AGRAWAL is ISO certified dealers of Musco Company in all over India for the EN-41-B material, RADHEKRISHNA, KOLSITE & WINDSOR are using their material from them, so here in local market EN-41-B is available for 60 Rs/kg only but where we are purchasing it for 120 Rs/kg, now see the difference between ours & others. POINT: 2 – WITHOUT DOING MATERIAL TEST, WE ARE NOT STARTING THE WORK: Which material we are purchasing, it having the 90% of Mild Steel & 10% of heard metals like aluminum, silicon, nickel, phosphorous, carbon, chromium & which material other manufacturer purchasing from local vendor it having 95 to 98% of Mild steel & 2 – 5 % of heard metal, so in the comparison of other manufacturers,our material is very higher grade, however we are doing test on it in ISO laboratories, after getting the positive report we are starting the work on it, either we are not starting the work.

34 POINT: 3 – BENIFIT OF OUR IN HOUSE CNC MACHINES & NITRIDING FURNACE: We are having all CNC machines which having of WINDSOR & KOLSITE, so we are same in machineries, moreover we have our own nitriding furnace, it is so 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 are maintaining 0.5mm in-depth layer of 64 to 68 HRC in Screw & Barrel. Point: 4 – WE ARE PROVIDING TUNGSTEN CARBIDE COATED SCREW PAIR We would like to inform you & we think you also aware of that the First Zone(Melting Zone) takes higher or more load in the comparison of other zone, so that's why we do coating on surface of same zone so it will give you better life against higher filler loading & other particles. Point: 5 – WE ARE PROVIDING HSS SLEEVE FITTED BARREL For Same reason, we provide sleeve on front barrel (which will be fitted on Melting Zone) which made from "High Speed Steel", it also give better life against wear & tear.
