1.1 BARREL Treatment :

LD ratio : 27:1

Treatment : Gas Nitriding
Capacity : 45 Kgs / hr. of HMHDPE.(As ICI works on solid bed pumping outputs can vary (+)(-) 10% depending on melt
index bulk density , hardness , co-efficient of friction
and shape of pellets.1.3 DRIVE

Motor : 10 hp AC motor of standard make.

Gear Box : Helical gear box with integral thrust bearing. The lubrication is through oil splashing and the whole gear box is water
Cooled

Pulley : Suitable as required2.1 DIE
Die Head : Rotating Die
Heating Zones : 3 No’s
Heating Load : 5.75 KW
Candle Filter : A special candle filterwould be provided. This would ensure filter change over time reduced by 50%. One does not need to disturb the die or extruder while changing the filter. 3.1 Cooling Ring
Blower : A high capacity medium pressure blower powered by 2
hp Motor . A damper valve is provided on the suction side
for control of the air quantity.

4.1 TAKE OFF : Fabricated from heavy channel and angle sections. Tower is having a height of 10 feet. : One cooling ring suitable for 75mm is made from aluminium alloy and has adjustable lips for air flow control. : Made of alloy steel, ground polished and plated. The li p size is 75mm.: 10 hp AC Variable frequency drive of standard make. The drive is digital and is self diagnostic. Gas Nitriding

Heating : Heating is in two zones out of which zone 2 is cooled by a 0.25hp blower.

Heating Load : 5.0 KW

Diameter : Iris ring : A variable height and variable diameter ring is fixed over the tower for holding the bubble properly.

Nip Rolls :
5.1 Winder : A single station surface winder is provided along with two winding shafts. A special wrinkle remover is provided just before the winder for wrinkle free film Drive : The drive is through 0.4hp torque motor.

6.1 Control Panel
Temperature : 5 PID temperature controllers indicating temp. of each zone7.1 SPARES 1.2 SCREW : Made of nitriding steel , hardened and ground with special mixing head, and shear element. : Electricals, Pneumatics and mechanical spares shall be provided at extra cost.: The control panel is made of heavy sheet metal and is front opening type.The panel is painted white from inside for clear visibility . An unique feature for this panel is an interlocking mechanism between each temp. controller and the main motor . Unless the actual temp. of each zone is reached the main drive can not be started in order to safe guard the screw against damage which can occur due to solidified mass of polymer. In other words, this would act as a cold start preventer. A flasher unit is provided which would continue flashing till the desired temp. is reached. A similar interlock also exists between the groove temp. & the main drive. . Controllers and a 6th temp. indicator of the groove temp. Drive : The drive is through 1 hp AC motor controlled by AC frequency drive. Speed : 10 to 60 m/min. Flatening Board. : The baord is made up of wooden slats fixed over an angle frame. The boards can be finely adjusted to get wrinkle free tubing. We also provide Universal Gusseting System.

Meterage : A line speed indication Energy Meter : A KWH meter. Embossing Roll : Complete Unit along with pneumatics shall be provided. The Nip rolls can handle a tubing size of 30". They are activated by two pneumatic cylinders and a solenoid valve It is driven by AC motor coupled with an reduction gear box. 50mm : Made of nitriding steel, single piece construction, ground and boned to high surface finish and close tolerance.
