BOTTLE PROCESSING EQUIPMENT

There are two basic molding methods for BOTTLE PROCESSING EQUIPMENT, one-step and two-step. In two-step molding, two separate machines are used. The first machine injection molds the preform, which resembles a test tube, with the bottle-cap threads already molded into place. The body of the tube is significantly thicker, as it will be inflated into its final shape in the second step using stretch blow molding.
In the second step, the preforms are heated rapidly and then inflated against a two-part mold to form them into the final shape of the bottle. PET preforms manufacturers in india are now also used as containers for candy, and by some Red Cross chapters to distribute to homeowners to store medical history for emergency responders.
In one-step machines, the entire process from raw material to finished container is conducted within one machine, making it especially suitable for molding non-standard shapes (custom molding), including jars, flat oval, flask shapes etc. Its greatest merit is the reduction in space, product handling and energy, and far higher visual quality than can be achieved by the two-step system.
Polyethylene terephthalate, commonly abbreviated PET, PETE, or the obsolete PETP or PET-P, is a thermoplastic polymer resin of the polyester family and is used in synthetic fibers; beverage, food and other liquid containers; thermoforming applications; and engineering resins often in combination with glass fiber.
