This document summarizes the key components and processes involved in plastic injection molding. It describes the hopper, barrel, ram, archimedes' screw, heaters, and mold and their functions. It provides details on the productivity and advantages of the recommended Krones machine, including lower power consumption, good control of temperature and AA percentage. It also lists the major equipment used, including a resin dryer, hoppers, hopper loader, operating air and chilled water systems. Finally, it specifies the number of staff required per shift and day.

1.  The Project of :
 Prepared by :
 Eng.M.hamdy
 Eng.A.sharkawy.

6.  The hopper – supplies the pellets into the
barrel
 The barrel – holds & melts the plastic at 270
deg.celisus
 The ram – injects the molten plastic into the
mould
 The Archimedes’ screw – feeds the plastic
along the barrel & helps to make sure the
pellets are molten
 The Heaters – melt the pellets

7.  The mould – defines the part shape and
cools the molten plastic to help solidifying
 The ejection ram – splits the mould tools to
eject the part

12.  Cost saving due to low gram preform for big sized
bottle
 Low power consumption 447 kw in comparison to
other machine (517kw)
 Recommended by Krones manufacturer.
 Remixer nozzle develop good control of AA
Percentage and give homogenous color .
 Good control of Temperature of the hot runner due
to step bystep thermocouple.
 Productivity :
For 96 cavity line : 57000 preform/hr
for 144 cavity line : 89000 preform /hr

14.  Resin Dryer.
consist of ladder , steel reinforced platform
and two blowers fitted with air filter one for the
process air and the other for the regeneration
air.
The air remove the humidity of PET resin.
 Hopper loader.

15.  Hopper.
this is the main material drying hopper.
capacity : 6000 litre
Insulated with 10 cm glasswhool to save
energy.
 Hopper loader :
This is 4-stage side channel vaccum blower to
load the hopper with Resin powder.

16.  Operating air :
Recommended ATLAS SCREW
COMPRESSOR GA45. or kaiser compressor.
 For chilled Water :
husky chiller which feed water at 15 deg. To
the mold
