The EP-BPET-70-V4 injection stretch blow molding machine is a precision-engineered 4-station system designed to streamline the production of high-quality plastic containers in a single heat cycle. By integrating injection, temperature conditioning, stretch blowing, and product take-out, this machine eliminates the risks of contamination and surface damage common in two-step processes. For manufacturers in Colombia seeking to comply with "Plan de Gestión Ambiental" and regional VOC regulations, this system offers a sustainable, energy-efficient alternative to traditional molding. It provides exceptional transparency and mechanical strength for PET, PETG, and PP materials, making it a perfect replacement for ASB and Aoki models in pharmaceutical and high-end cosmetic lines.
Furthermore, our EP-BPET-70-V4 model is compatible with the molds of the Japanese ASB 12M model.
3. The 4-Station Injection Stretch Blow Molding Machine Process
The core philosophy of the injection stretch blow molding process lies in its seamless continuity. Station 1 handles the precision injection of the preform parison, where critical neck dimensions are established. Unlike conventional methods, the preform is immediately transferred to Station 2 for temperature adjustment and optional tail cutting, ensuring a uniform thermal profile. Station 3 is the heart of the system, where biaxial stretching and blowing occur, resulting in superior clarity and barrier properties. Finally, Station 4 automates the take-out process, delivering a finished, flash-free product. This integrated one-step injection stretch blow molding machine minimizes human error and significantly reduces the factory footprint, providing a competitive edge for Colombian enterprises aiming for global quality standards like ISO 9001 and FDA compliance.
4. Injection stretch blow molding machine: Material Versatility & Global Standards
Material flexibility is a hallmark of the injection stretch blow molding products generated by our V4 series. The system is optimized for PET (Polyethylene Terephthalate), known for its recyclability and transparency, but it also excels with PETG, which offers enhanced toughness for high-end luxury packaging. For the Colombian food industry, the machine efficiently processes PP (Polypropylene), providing heat-resistant containers for hot-fill applications. Advanced engineering plastics like PC and Tritan (BPA-free) are also supported, enabling the production of reusable sports bottles and high-clarity baby feeding bottles. By utilizing premium alloys for our injection stretch blow mold components, we ensure a long service life and resistance to thermal fatigue, meeting international hygiene standards for food-grade contact materials.
