The blank tube heating, forming bottleneck, sealing and cutting are the processing procedures of the blank before forming and stretching the bottle products; Then stretch and blow molding the product. The preform is heated to between vitrification temperature and melting temperature of raw material and polypropylene resin is 145-155℃ before stretching; To reach the temperature of each part of the bottle body and heat evenly before stretching work. When the product is stretched and blown, the stretching mandrel is inserted from the bottle mouth end to the bottom of the bottle to stretch and blow the compressed air to blow the bottle blank and complete the stretching and blow molding work of the bottle blank.
The ratio of stretch blow molding bottle billet is the product of two ratios of stretch ratio and blow ratio, which is an important technological condition to improve the properties of products. The stretching ratio of general PP products is controlled in the range of 6-10.
