Zero-Failure Blowing Machine Testing: 100% Quality Assurance for Products

Fully automatic 2-cavity beer bottle blowing machine

A fully automatic 2-cavity beer bottle blowing machine is a specialized industrial machine used in the beverage industry to produce PET (polyethylene terephthalate) beer bottles. It operates by inflating preforms into fully shaped bottles using a blow molding process. The "2-cavity" designation means it can produce two bottles simultaneously in each cycle, optimizing production efficiency.

Key Features of a Fully Automatic 2-Cavity Beer Bottle Blowing Machine:

1. High Efficiency

   • Produces two bottles per cycle, increasing output compared to single-cavity machines.

   • Cycle times typically range from 3 to 6 seconds, depending on bottle size and design.

2. Fully Automated Operation

   • Automatic loading of PET preforms.

   • Heating, stretching, blowing, and ejection are all automated, reducing labor costs.

   • PLC (Programmable Logic Controller) and HMI (Human-Machine Interface) for easy control.

3. Precision Blow Molding Technology

   • Infrared heating system ensures uniform preform heating.

   • High-pressure blowing (up to 40 bar) for consistent bottle wall thickness.

   • Servo-driven stretch rods for precise stretching.

4. Energy-Saving Design

   • Some models feature servo motors to reduce power consumption.

   • Optimized air recovery systems to minimize compressed air waste.

5. Versatile Production

   • Capable of producing different bottle shapes and sizes (typically 300ml to 2L for beer bottles).

   • Adjustable mold systems for quick changeovers.

6. Durability & Low Maintenance

   • High-quality stainless steel and hardened components for longevity.

   • Self-lubricating systems reduce wear and tear.

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.
• Self-Diagnosis Function: Built-in sensors detect malfunctions automatically, reducing defects and improving reliability.

4. Flexibility & Versatility

• 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.
