A promise of quality can only be made when durability and design are equally emphasized. At Chemco, we adhere to strict quality assurance tests to ensure that all of our products are of superior quality. Our team of experts ensures high standards of quality at every stage of production, from the process to the final product. We only partner with suppliers who maintain the same quality standards, to prevent any errors during subsequent processes. Our products are evaluated based on two main criteria: durability and dimensional accuracy.
PET bottles, containers, and jars are typically manufactured using one of two processes: a single-step process or a double-step process. The single-step process combines the preform injection process and the preform stretch-blowing process, producing a product directly from the plastic resin on a single machine. The double-step process involves two separate stages, with preform injection molding performed on an injection machine and re-heating and stretch-blowing carried out on a separate blowing machine.
