? ? PET bottle blowing machine is divided into two kinds of rotary and straight lines according to the conveying mode of the bottle blank. Rotary bottle blowing machine production capacity is high, the speed is fast, the design is complex, the price is also high. The typical rotary blow molding machine is France Sidel of SBO series, its type sbo24 blow bottle machine per hour production reached more than 20000 bottles, at present China's tech long also successfully developed rotary bottle blowing machines, production rate reached per hour more than 8000 bottles; straight blow bottle machine typical is the Japanese ASB and Aoki, generally speaking, the mechanical design is relatively simple, but production will become a bottleneck, it is difficult to exceed the 6000 bottles / hour.
? Temperature control is directly related to the uniformity of the plastic, which is the key to the success or failure of blowing products. Mold and hot runner design and precision, but also determine the merits of the product quality.
? At present, China for PET bottle production of injection stretch blow moulding equipment is basically dominated by imported products, especially in high speed and a large volume of products production, domestic equipment can't compete. It is worth mentioning that, at present, the production of large capacity PET hot filling bottle blowing machine manufacturers rarely, it seems that only ASB repeatedly blowing process to obtain a satisfactory effect.
