Automatic 4 cavity pet bottle blow molding machine through a certain process blow the pet preform into plastic pet bottles. It mainly used to produce the carbonated bottle, mineral water bottle, pesticide bottle oil bottle cosmetics, wide-mouth bottle and hot fill bottle and so on.
PET Blowing Bottle Machine. We manufacture every set of equipment with 100% attention. We keep promise to every client using best quality of material, advanced technology, and famous brand of accessories such as PLC, motor, etc. In addition, if you have any questions of our machine, please kindly feel free to contact us.
1. High Production Efficiency
High-Speed Molding: Multi-cavity mold design enables simultaneous production of multiple bottles, significantly boosting output.
Automated Control: Fully automated process (feeding → heating → blowing → demolding) minimizes manual intervention and shortens cycle time.
Quick Mold Change System: Modular mold design allows rapid switching between different bottle shapes, reducing downtime.
2. Energy Saving & Eco-Friendly
Low Energy Consumption: Optimized heating systems (e.g., infrared) and servo motors reduce power usage.
High Material Utilization: Precise PET material control minimizes waste, achieving over 95% yield rate.
Recyclable Compatibility: Supports rPET (recycled PET) materials, aligning with sustainable production trends.
3. High Precision & Stability
Intelligent Temperature Control: Real-time monitoring ensures even heating, preventing deformation or uneven wall thickness.
Stable Hydraulic/Pneumatic Pressure: Accurate blowing pressure ensures consistent bottle strength and uniform wall distribution.
Wide Bottle Size Range: Capable of producing bottles from 50ml to 5L, suitable for beverages, cosmetics, pharmaceuticals, etc.
Customizable Designs: Adjustable molds and parameters allow personalized shapes, textures, and threads.
Multi-Process Compatibility: Supports both one-step (injection-stretch-blow) and two-step (preform + blowing) methods, adapting to diverse production needs.

Frequently Asked Question
Answer: It depends on the model (single or multi-cavity). Standard machines produce 1,000–5,000 bottles/hour, while high-speed models can reach 10,000+ bottles/hour. We customize solutions based on yo...
Answer: Yes! Our machines support virgin PET and rPET (up to 30–50% recycled content, depending on bottle quality requirements). We optimize heating and blowing for stable performance.
Answer: With our quick mold-change system, switching takes 15–30 minutes (vs. 1–2 hours for traditional machines), minimizing downtime.
Answer: Advanced servo-driven machines save 20–30% energy vs. hydraulic models. For example, a 20-cavity machine consumes ~25–35 kW/h.
Answer: Our machines feature:Precision temperature control (±1°C)Automatic wall thickness adjustmentReal-time defect detection (rejects faulty bottles)
