These machines are usually used for the manufacture of PET bottles DNG material, where the process of formation of products through the 3 stages of injection, stretching and blowing but DNG certain type of screw 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 the process of making preform until it becomes the bottle in one machine
2.DOUBLE (TWO) STAGE
-The process of making DNG preform injection machine and then a new engine in DNG stretching BLOW Blow Molding (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 inside of the preform
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 before curl
7.STRECHING ROD
-To encourage the concurrent preform blow dng in the process of formation of the desired product.
8.STRIPPER PLATE
