Material Storage (Silo) Aluminum, stainless steel

bags or jumbo bags at the feed rate from 3 to 15

. Minimize material handling saves raw material

4 Material Storage (Silo) Aluminum, stainless steel and carbon steel with coating from 5m 3 to 300m 3 storage capacity. Silo feeding system transfer material from 25 kg bags or jumbo bags at the feed rate from 3 to 15 Tons/Hr.. Minimize material handling saves raw material Space saving of raw material storage Helps to control raw material inventory Closed loop conveying avoid contamination Labour saving

5 Silo Feeding System

Hopper Loader It is vacuum based system.

6 Hopper Loader It is vacuum based system. Vacuum blower creates vacuum inside the body thus material conveying takes place. Advantages:- Labour saving. Material saving due to spillage. No contamination. Less handling of material. Consistent feeding of raw-material.

Advantages Fully automatic material transfer Labour saving Flexibility in handling various materials Reduced

7 Central Conveying System The central conveying system is designed to convey different raw materials to different machines from main raw material storage. Advantages Fully automatic material transfer Labour saving Flexibility in handling various materials Reduced spillage / wastage Raw material convey from main storage area in very organized way Neat and clean work area Consistent material feeding Modular system In line dust removal

8 Dosing Mixing Conveying System Advantages of on-line dosing system over conventional process Mixing ratio can be adjusted and changed during production. Instant setting can be achieved by changing on-line mixing ratio. Avoids manual errors and saves time & material. Saving in quantity of master batch or pigment.

9 Dosing Mixing Conveying System Direct Colouring Unit for Master Batch Screw Feeder for Master Batch Dosing System with Mixer

Dosing Mixing Conveying System Working Principle Gravimetric Dosing Weighing Hopper Dosing Station with Slider Load Cell Viewing Window with Agitator

The load cell registers actual weight of individual component and transfer to controller.

10 Dosing Mixing Conveying System Working Principle Gravimetric Dosing Weighing Hopper Dosing Station with Slider Load Cell Viewing Window with Agitator Materials will convey by hopper loader in to buffer hopper on dosing station. Individual component is weighed into a weighing container as per the set %. The load cell registers actual weight of individual component and transfer to controller. Controller will verify the weight with set value and do correction if require, weighing & correcting continuously. Online mixer with buffer hopper mix all materials homogeneously. Finally recipe will be feed to the extruder

11 Dosing Mixing Conveying System Advantages Gravimetric Dosing Very accurate dosing with 0.1%. 100 recipe storage with password protection. Batch history and consumption records. 6 components dosing and mixing. Complete Modular Concept anything can be fitted anywhere. Bigger size mixer having 3 batches mixes together gives homogeneous mixed recipe. No Tool Concept dismantling without tools.

It can provide numerous recipes from just one system.

12 Octopus The Octopus System Octopus is an off-line multicomponent, multi-recipe gravimetric dosing-mixing-conveying system. It can provide numerous recipes from just one system. Hence, if there is more than one multi/mono layer film plant, Octopus system is the solution for smooth handling of material.

13 Extrusion Process Control System Prasad Koch Gravimetric EPC (Extrusion Process Control) System monitor & control exact throughput and gives cutting edge technology to Extrusion Process - result in even thickness and better GSM control. Weighing Hopper Applications

A computer with intelligent software detects the fluctuations and compensate / correct them by means of suitable system.

14 Gravimetric Loss In Weight System In EPC - we monitor actual output and change the screw speed so that even though other parameters are changed, output remains constant. EPC System monitors material consumption of each layer and transfers it to the process computer. A computer with intelligent software detects the fluctuations and compensate / correct them by means of suitable system. Process Computer not only controls the output and ratio of each layer but also changes the line speed (Haul off) so that ultimate thickness of Film will be maintained. Data can be logged & printed with user interface

16 Chilling Plant Air / Water Cooled Chilling Plant Chilling Plant with Screw Compressor

17 Chilling Plant SELECTION CRITERIA Application Material to process Output in kg/hr. No. of machine Distance between chiller and consumer Ambient condition

18 Mould Dehumidifier Purpose: To prevent mold sweating while circulating lower temperature water in the mold. Requirement of Process: To have dry air at lower temperature than the ambient temperature at desire flow to prevent mold sweating on mold surface.

Desired air temperature can be achieved in shorter time.

19 Air Chiller Advantages of Air Chiller Direct cooling technology for air blown film lines. Consistency in air temperature regardless of environmental condition improves film quality. Desired air temperature can be achieved in shorter time. The Air Chillers are design to adjust the power consumption according to the actual requirements. Low air temperature can be achieved at lower power consumption compare to conventional water to air chilling. Energy saving up to ~15% compare to conventional system.

20 Hopper Dryer Capacity from 15 Ltrs to 5000 Ltrs Useful to remove surface moisture from material Generally used for non hygroscopic material Always use ambient air for drying process

ambient air in material drying Consistent output irrespective of

21 Dehumidified Air Dryer Remove internal moisture content from material Most efficient closed loop drying system No use of ambient air in material drying Consistent output irrespective of ambient condition. Must for all hygroscopic materials like PET, PC, PBT, PA.

22 Dehumidified Air Dryer Installation type with multiple drying bins

23 Granulator We live in the world dominated by high speed. But there are times when being slow is key to result. In plastics processing industry, engineering plastics is becoming increasingly important. The cost of these type of material is so high that re-use of sprues & rejected parts become essential for economy.

24 Granulator Slow speed granulator for Engineering plastic Slow Speed Granulator No knife No blade No screen No noise No dust This technology works on very slow speed - Just 1 revolution in 2 seconds. Successful technolgoy & proven design.

25 Granulator Granulator with material transport and dust separation Open hearted concept

moulded parts by proper melt flow in the cavity Controls warping and distortion behavior of the

26 Mould Temperature Controller Oil based / Water based The temperature of the mould influences the quality and economy of operation of the production process Improves surface quality of the finish moulded parts by proper melt flow in the cavity Controls warping and distortion behavior of the products Inadequate heating and cooling can also lead to the formation of stress cracks and breakage of moulded parts
