The EP-HGY250-V4 operates through a sophisticated four-station process that seamlessly integrates injection molding and blow molding into a continuous production cycle. Each station performs specialized functions to create high-quality containers with precision and efficiency.

1

Injection Station

The process begins with the injection station where molten PET resin is precisely injected into the preform mold. The servo-controlled injection system maintains exact pressure (300KN clamping force) and temperature to create uniform preforms. The screw diameter options (50mm, 55mm, or 60mm) accommodate various production volumes, with theoretical injection capacities ranging from 340cm³ to 480cm³. The advanced servo motors ensure consistent shot weight and minimal material waste.

↓
2

Conditioning Station

Following injection, preforms transfer to the conditioning station where precise temperature management occurs. The TEMP regulating core stroke (300mm) and barrel stroke (300mm) work in conjunction with the nano-infrared heating system to bring preforms to optimal stretching temperature. This station ensures uniform heat distribution throughout the preform, critical for achieving consistent wall thickness in the final product. The hydraulic pressure control valve from Taiwan's YUKEN provides stable temperature regulation.

Stretch Blow Station

The conditioned preforms advance to the stretch blow station, where the magic happens. A stretch rod extends through the preform while high-pressure air (2.0-3.5 Mpa) inflates it against the precisely machined blow mold. The blow clamping force of 200KN ensures proper mold closure during this critical phase. The Japanese servo motor controlling the turntable provides smooth, accurate positioning. The blow core stroke (300mm) accommodates various bottle heights, while the hydraulic or dual servo motor mold clamping system with high-precision compensation function guarantees uniform wall distribution.
