This PET blow molding machine is primarily utilized to form plastic bottles by inflating heated and softened plastic parisons within molds. In the cosmetics sector, this machine is essential for manufacturing various shapes and sizes of bottles, such as those for lotions, sprays, serums, and more.
1.Heating and Softening: Plastic granules or preforms are heated to a temperature where they become pliable and easy to mold.
2.Stretching and Blowing: The softened plastic is fed into a mold, where it's stretched into a long tube-like shape. Then, high-pressure air is blown into the tube, causing it to expand and conform to the shape of the mold cavity.
3.Cooling and Solidification: Once the plastic cools and solidifies, the mold opens, and the finished bottle is ejected.
