An 1810 PET preform is a pre-molded shape made from PET resin that is used as a starting point for creating PET bottles or containers. The term "1810" refers to the specific dimensions of the preform, with "18" indicating the neck diameter in millimeters and "10" denoting the preform's height in centimeters. These preforms are produced through injection molding and are then further processed into bottles via a blow molding process.

Design Features of 1810 PET Preforms

  1. Neck Design: The neck of the 1810 PET preform is designed to accommodate standard closure systems, such as screw caps or snap-on lids. The neck diameter is precisely engineered to ensure compatibility with various types of closures, providing a secure seal for the final product. The neck design also includes features like threads or ridges, which are crucial for proper sealing and user convenience.
  2. Wall Thickness: The wall thickness of the 1810 PET preform is carefully controlled to balance strength and flexibility. The preform's walls are designed to be thick enough to withstand the high-pressure conditions of the blow molding process while remaining lightweight. Uniform wall thickness ensures consistent quality and performance of the final PET bottles.
  3. Body Shape: The body of the 1810 PET preform is designed to facilitate efficient blow molding. The preform typically has a cylindrical shape with a slightly tapered end to ease the transition from preform to bottle. This design ensures that the preform can be uniformly expanded and shaped during the blow molding process, resulting in a high-quality finished product.
