Blow Molding Machine Inthe Region of 20 Thousand Bph


Product Overview


The Auto Stretch PET Bottle Blowing Machinery redefines PET container manufacturing with its precision engineering and material efficiency. Capable of producing 18,000 bottles/hour (500ml size), it transforms preforms into lightweight yet robust containers through a 4-stage stretching process (preheat → stretch rod → high-pressure blow → cooling). This technology reduces PET usage by 15% per bottle compared to conventional blowers, lowering both material costs and carbon footprint. Its compatibility with food-grade and cosmetic-grade PET makes it a versatile choice for multi-industry manufacturers.


Features


High-Speed Production: 18,000 BPH for 500ml bottles; 12,000 BPH for 1.5L bottles, with a 0.3% defect rate (vs. industry average 1.2%).

Energy Savings: Infrared heating zones with quartz tubes cut power use to 0.8kWh per 1,000 bottles, 45% less than ceramic heaters.

Precision Control: Siemens S7-1200 PLC regulates stretch ratio (1:3.5 vertically, 1:2.8 horizontally) for uniform wall thickness (±0.02mm).

Quick Mold Change: Magnetic clamping system swaps molds in 18 minutes, with mold storage racks for 10+ configurations.

Safety Compliance: Dual-channel emergency stops, light curtains (EN ISO 13849-1), and automatic pressure relief valves prevent accidents.


Applications


Beverage Industry: Produces hot-fill bottles (up to 85°C) for juices and cold-fill variants for carbonated drinks, with anti-burst design.

Cosmetics: Creates UV-protective amber PET bottles for serums and transparent containers with matte finishes for luxury skincare.

Pharmaceuticals: Manufactures tamper-evident bottles with child-resistant caps, meeting USP Class VI standards for extractables.

Household Goods: Forms squeeze bottles with controlled deformation for dish soap and rigid containers for laundry detergents.


FAQ


Q: What preform neck finishes are compatible?

A: Supports 28mm PCO, 38mm ROPP, and custom neck sizes, with interchangeable neck rings for quick adaptation.

Q: How is bottle quality inspected?

A: Inline vision systems check for wall thickness variations, flash, and transparency, rejecting defective units automatically.

Q: What is the air pressure requirement for blowing?

A: 35–40 bar for standard bottles; 45 bar for carbonated beverage containers to withstand internal pressure.

Q: Can it produce bottles with handles?

A: Yes, with optional handle insertion modules that integrate seamlessly into the blowing cycle.
