How to Introduction to the Blowing Process of PET Plastic Pump Bottles
PET Plastic
Pump (KEXON) bottles can be divided into two categories, one is a pressure
bottle, the other is a pressureless bottle. 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.
The quality of the preform depends largely on the quality of the PET material. The material that is easy to inflate and easy to set should be selected and a reasonable preform molding process should be established. Experiments show that the preforms of PET materials with the same viscosity are easier to blow molding than the domestic materials; while the same batch of preforms has different production dates, the blow molding process may also have a big difference. The advantages and disadvantages of the preform determine the difficulty of the blow molding process. The requirements for the preform are pure, transparent, free of impurities, no discoloration, suitable length of the spot and surrounding vignetting.
