Stable Operation

Hydraulic cylinder mold clamping with dual servo motor compensation ensures consistent pressure distribution. Advanced cooling systems maintain optimal operating temperature for continuous 24/7 production.

Injection Molding

Molten PET/PETG material is injected into precision molds to form preforms. The servo-controlled injection system ensures consistent wall thickness and optimal molecular orientation.

Temperature Conditioning

Preforms are maintained at precisely controlled temperature using advanced heating systems. This stage ensures optimal material viscosity for the stretching process without energy waste.

Stretch Blow Molding

Mechanical stretching rods elongate the preform while high-pressure air expands it against cooled molds. This biaxial orientation process enhances mechanical strength and clarity.

Cooling & Ejection

Finished bottles undergo rapid cooling to set their final shape. Automated ejection systems remove bottles from molds, ready for quality inspection and downstream packaging processes.

1. What are the main advantages of one-step ISBM over two-step processes?

One-step ISBM eliminates the need for preform storage, transportation, and reheating, resulting in approximately 30% energy savings. The continuous thermal cycle prevents material degradation and contamination, ensuring superior product quality. Additionally, the reduced process steps lower labor costs and minimize floor space requirements. The one-step approach is particularly advantageous for applications requiring strict hygiene control, such as pharmaceutical and cosmetic packaging.

2. What materials can the EP-HGY250-V4-B process?

The machine is designed to process multiple thermoplastic materials including PET (polyethylene terephthalate), PETG (glycol-modified PET), PC (polycarbonate), PCTG (glycol-modified polycarbonate), and PP (polypropylene). Material selection depends on application requirements such as chemical resistance, clarity, barrier properties, and FDA compliance. Our technical team can recommend optimal material specifications for your specific products and provide processing parameter guidance.

3. How long does mold changeover take?

Standard mold changeover typically requires 25-40 minutes depending on operator experience and bottle complexity. The machine features quick-lock mold mounting systems and automated parameter recall through the PLC interface. For facilities with frequent product changes, we recommend maintaining a set of pre-heated backup molds to minimize downtime. Our training program includes comprehensive mold changeover procedures to optimize efficiency.
