PRODUCT DETAILS

Product Overview

Injection molding, preform conditioning, stretch blowing and bottle take-out are integrated in one machine. The four-station layout transfers the preform between stages without a separate preform-reheating production line.

Applications

Catalogue examples include cosmetic packaging, personal-care bottles, wide-mouth jars and shaped transparent containers. Bottle size and shape must fit the selected cavity configuration.

Single-Stage ISBM Features

  • Integrated injection and stretch blow molding supports production from resin to finished containers in one machine.
  • Preform and bottle tooling can be matched to the required neck finish, container shape and production target.
  • The four-station arrangement includes preform conditioning and pre-blowing before stretch blowing.
  • Integrated processing reduces intermediate handling and supports clean container production.
  • The catalogue lists PET, PETG, transparent PP, SAN, PC, PS, PMMA and Tritan applications. Confirm resin and tooling for the intended container.
  • The equipment is described with both injection blow molding and injection stretch blow molding capability, subject to the selected tooling and process.

The catalogue cites a 45% energy-saving reference for the BPET series. Compare consumption using the intended resin, container, mold and production setup.
