Semi-automatic PET Blow Molding Machine

Flexible Manufacturing: 150 to 1100 BPH for Custom & Large Capacity Containers

Semi-automatic stretch blow molding machine manufacturer
  • ✅ Operational Efficiency: Produces 150 to 1100 BPH depending on bottle size and operator rhythm.
  • ✅ Extreme Versatility: Configurable to blow bottles starting from 1L all the way up to massive 20L gallons.
  • ✅ Clamping Mechanism: Utilizes a heavy-duty double crank mold locking system for highly stable and fast operation.
  • ✅ Thermal Control: Independent infrared heating ovens ensure preforms are rotated and heated equally.
  • ✅ Customization: Supports hot-filling designs (EPS200B) and special-shaped crafting perfectly.

System Overview & Pneumatic Innovation

For startups, custom packaging facilities, or specialized low-volume runs, a fully automatic line may not offer the best ROI. The EPS Series Semi-automatic Blow Molding Machine bridges this gap perfectly. Designed with immense durability, the machine adopts a double crank to adjust the mold. This heavy locking mechanism is incredibly stable and fast, easily handling the high blowing pressures required for thick-walled containers.

To guarantee bottle structural integrity, the air system has been meticulously divided into two distinct parts: the pneumatic action part (for mechanical movement) and the high-pressure bottle blow part. This segregation guarantees sufficient and steady air pressure for both the mechanical clamping and the actual PET stretching process, preventing pressure drops that cause deformities in large 20L containers.

Turnkey Integration: Precision Molds & Auxiliary Machinery

A semi-automatic operation still demands industrial-grade reliability. We supply comprehensive turnkey systems designed to synchronize flawlessly with the EPS series.

Custom Blowing Molds: We engineer high-strength aluminum and steel molds utilizing advanced CNC technology. Because manual intervention is required to transfer heated preforms, mold design includes specialized centering rings to ensure rapid, error-free placement. These custom molds guarantee zero parting line defects, whether you are blowing a standard 1L bottle or a complex geometric craft.

Auxiliary Equipment Matching: The semi-auto process relies heavily on stable air pressure. We provide tailored high-pressure air compressors (up to 3.0MPa) and industrial chillers that connect directly to your EPS machine. This complete integration prevents pressure bottlenecks and maximizes the lifespan of your pneumatic cylinders.

Applications: Versatile Packaging & Hot-Filling

The EPS semi-automatic series is the ultimate platform for high-mix, low-to-medium volume manufacturing runs. Its manual loading mechanism allows operators to process a vast array of specialized preforms.

  • Large 20L Water Gallons: The EPS-3S0A(20L) model features an expanded 580*390mm pillar space to handle massive 20-liter PC/PET replacement water jugs.
  • Hot-Fill Beverages: The specialized EPS200B (Hot-filling) unit integrates robust thermal resistance protocols to produce bottles capable of handling high-temperature juices and teas.
  • Cosmetics & Special Crafts: Ideal for highly asymmetrical, custom-designed cosmetic containers that require frequent mold changeovers.
  • Wide-Mouth Food Jars: Operators can comfortably load wide-neck preforms into the stretching cavity without complex automated unscramblers.

Investment Analysis: Semi-Automatic vs. Fully Automatic SBM

Evaluation Metric Semi-Automatic (EPS Series) Fully Automatic (EP.ES Series)
Initial Capital Investment Extremely low. Highly accessible for startups and localized production. Higher initial cost, justified by mass-scale economies.
Production Flexibility Maximum. Instant changeovers between 1L to 20L configurations. High, but formatting changes require adjustments to automated rails.
Labor Requirements Requires an operator to manually transfer preforms from oven to mold. Minimal intervention. Fully automated feeding and ejection.
Output Capacity 150 to 1100 BPH based on operator speed and model. 1800 to 9200+ BPH for continuous 24/7 mass production.
