INJECTION BLOW stretching
These machines are usually used for the manufacture of PET bottles DNG material, where the process of formation of product through the three stages of injection, stretching and blowing but DNG certain types of screws can be used also for other materials such as Polypropilene (PP) dng a particular grade.
PET bottle-making process itself usually there are 2 ways
1.SINGLE (ONE) STAGE
-All processes from preform manufacturing to be a bottle in one machine
2.DOUBLE (TWO) STAGE
DNG-making process preform injection machine and then the new DNG BLOW Blow Molding stretching machine (separate)
COMPONENTS AND FUNCTIONS OF MOLD ISB
1.INJECTION cavity preform
-To make the outside of the preform shape
2.CORE ROD
-To make the preform inside
3.LIP cavity
-To make the mouth of the bottle preform
4.NECK RING
-For the manufacture of the preform neck
5.BLOW SHELL
-To create the desired product form
6.HEATING POT (POT CONDITIONING)
-For conditioning the preform temperature prior to curl
7.STRECHING ROD
-To encourage the same preform blow dng in the process of forming the desired product.
8.STRIPPER PLATE
-To drop a product that has been established
PART 9.BOTTOM
-To form the bottom bottle
