High-Efficiency Semi-Automatic Four-Cavity PET Blow Molding Machine: Cost-Effective Solutions for Medium-Volume Production


METO Machinery proudly presents our High-Efficiency Semi-Automatic Four-Cavity PET Blow Molding Machine—a precision-engineered system designed specifically for manufacturers requiring reliable, cost-effective bottle production at medium volumes. This 4-cavity semi-automatic machine represents the perfect balance between manual flexibility and automated efficiency, delivering production speeds of 1,800-2,200 bottles per hour for containers ranging from 0.1L to 2L . Ideal for startups, regional bottlers, and businesses with varied production needs, our machine combines robust construction with user-friendly operation to deliver exceptional value.

Key Features

1. High-Output 4-Cavity Design

Our four-cavity configuration significantly boosts production efficiency:

  • Simultaneous molding of four bottles per cycle maximizes throughput

  • ~30% higher output compared to single or dual-cavity models 

  • Theoretical output of 1,800-2,200 bottles/hour for 0.1-2L containers 

  • Flexible production capable of handling various bottle shapes including carbonated drink, water, oil, pharmaceutical, and cosmetic containers 

2. Advanced Infrared Heating Technology

Uniform preform heating is critical for consistent bottle quality:

  • Infrared heating system with preform rotation during heating ensures even temperature distribution 

  • Passing and rotating transport method guarantees preforms are heated equally for optimal material stretching 

  • Adjustable heating zones accommodate different preform structures and sizes

  • Penetrating power of infrared lamps ensures rapid and reliable heating 

3. Precision Stretch Blow Molding

Our machine utilizes proven stretch blow molding technology:

  • Biaxial orientation ensures uniform wall thickness and superior mechanical strength

  • Controlled stretch rod movement provides optimal material distribution

  • High clamping force of 180KN ensures mold closure integrity during blowing 

  • Mold opening stroke of 110-210mm (adjustable) accommodates various bottle heights 

4. Durable Construction

Built for long-term reliability in industrial environments:

  • Corrosion-resistant stainless steel construction extends equipment lifespan and maintains hygiene standards 

  • Base welded from Q235B 200×70 steel ensures stable operation 

  • Clamping system made of casting finish machining guarantees stable and reliable performance 

  • Outer structure painted for attractive appearance and durability 

5. User-Friendly Operation

Designed with the operator in mind:

  • Programmable touchscreen interface allows easy customization of temperature, pressure, and cycle parameters 

  • PLC-based control system with Chinese-made operation panel ensures stable and reliable operation 

  • Semi-automatic operation balances precision with flexibility for medium-scale production lines 

  • Manual preform loading reduces initial investment while maintaining production efficiency

6. Premium Components

We use only high-quality global components:

  • Main pneumatic parts from FESTO (Germany) ensuring reliable performance 

  • High-quality electrical components from world-famous brands 

  • CE-certified safety features including emergency stops and guarded moving parts
