They do not require manual secondary processing, save labor, and are hygienic and meet the GMP requirements for pharmaceutical packaging. They are especially suitable for the production of pharmaceutical bottles. 2 The appearance of the product is beautiful, the size of the bottle mouth is accurate, and the weight of the plastic bottle is stable. 3 The plastic product is made by one-shot blow molding of the injection type embryo, and there is no waste at the mouth and the bottom of the bottle, and the bottle mouth has a smooth sealing performance. 4 Suitable for the production of high-grade and exquisite plastic hollow products, such as cosmetic bottles, baby bottles, space cups, light balls, etc. The injection blowing process has several disadvantages compared to the extrusion process: 1 The process is complicated, and the mold processing is difficult and difficult to master. 2 There are many mold parts, long production and processing cycles and high cost. 3 Not suitable for multi-variety, small batch products.
