2 liter pet bottle blowing machine

Types of 2-liter PET bottle-blowing machines

The 2 liter PET bottle blowing machine takes plastic preforms and turns them into PET bottles of various sizes and shapes. PET, or polyethylene terephthalate, is a robust, lightweight plastic ideal for making transparent bottles. The process of blowing PET bottles involves heating the preforms, stretching them, and then blowing air into them to expand them into bottle shapes.

PET bottle-blowing machines, as a result, have been divided into three major categories to see how they fit into the overall production line and the manufacturing process. These categories are as follows:

• Injection Stretch Blow Molding (ISBM) machines:

  These machines take plastic pellets, inject them into a mold to create a preform, and then stretch and blow the preform to form the final bottle shape. ISBM machines combine the injection molding, stretching, and blow molding processes into one compact system, which is fully automated and can be easily adjusted to meet different production needs. They have fast production rates and can make high-precision preforms with excellent quality control.

• Extrusion Blow Molding (EBM) machines:

  These machines melt plastic resin into a parison (hollow tube) and then inflate the parison inside a mold to form the bottle shape. EBM machines are suitable for producing large bottles or containers, the accuracy is lower than that of the injection and blow-molding machines, and the production rate is also lower.

• Rotary blow molding machines:

  These machines use a rotary system to stretch and blow mold the preform simultaneously, allowing for high-speed production of bottles. Additionally, they have a flexible setup and ease of operation, which makes meeting various production needs possible. Moreover, their quality control is excellent, and they are suitable for making bottles at a rapid rate.

Overall, the 2-liter PET bottle-blowing machine fulfills an essential demand in the PET bottle-making process by shaping preforms into final products. With the advancement of scientific and technological progress, the evolution of this blowing machine continues as it moves toward a more energy-saving, environmentally-friendly, and efficient automated production mode.
