The blow molding of Pet Preform can be divided into two categories, one is a pressure bottle, such as a bottle filled with carbonated carbonated beverages; the other is a pressureless bottle, such as a bottle filled with water, tea, edible oil, and the like. The tea beverage bottle is a modified PET bottle blended with polyethylene naphthalate (PEN) or a composite bottle of PET and thermoplastic polyarylate. It is classified into a heat bottle and can be heat resistant to 85 ° C or higher; Cold bottles do not require heat resistance. The hot bottle is similar to the cold bottle in the forming process. The author mainly discusses the molding process of pressurized beverage bottles in cold bottles.
With the continuous advancement of technology and the scale of production, PET bottle blowing machines are becoming more and more automated, and production efficiency is getting higher and higher. Equipment production capacity continues to increase, from the previous production of thousands of bottles per hour to the current production of tens of thousands of bottles per hour. The operation has also evolved from the past manual button type to the current full computer control, which greatly reduces the difficulty of the process operation and increases the stability of the process.
