Study to be possible stretch blow mold type two stage form bottle water drink polypropylen NO 6024

Abstract

Bottle of poly propylene (Polypropylene: PP) to replace conventional non-conventional polycarbonate bottles. (Polycarbonate) are used as bottles and water bottles, toys, household goods, which are BPA-contaminated and poly ethylene Terephthalic acid (Polyethylene. Terephthalate) PET water bottles, juice bottles. , Bottles And bottles and other drugs and chemicals have been canceled. Then turning to the bottle to PP because of the lightweight bottles float on water. Plastic and white The plastic safety can be reused many times (even used) in the UK has the plastic water bottles, poly propylene and (Polypropylene: PP) to make water bottles so long but not as popular as bottle caps. open it (lid torn) bottle shape is beautiful with a little input. The process is a extrusion blow but from research using the dryer Injection blow (Stretch Blow) has studied the creation of injection molded preform 19 gram in order to blow a 500 ML size thickness. Preformed from 3.34 mm to 3.46 mm, the average measured height of the preform from a mean of 70 mm measured at 69.88 m. m., the oldest of the preform. the average measured 25 mm and 24.96 mm is how a 500 ML size bottle blow molding blow molds percent discrepancy between the form specified. Average Percentage 0.0853 experimental results Blow the preform 19 gram of the injection can be molded into the bottle completely and can not be used as drinking water is due to the equipment used. blown trial Need to study next.
