High-Speed 4 Cavity PET Blow Molding Machine | [Yushun Machinery]

What is a Fully Automatic 4 Cavity PET Blowing Machine?

It is a type of Stretch Blow Molding (SBM) machine designed to transform pre-formed PET plastic test tubes (called preforms) into finished bottles (like water, soda, oil, or detergent bottles) in a continuous, automated cycle.

  • Fully Automatic: The entire process—from feeding preforms into the machine to ejecting finished bottles—is automated without the need for manual intervention between cycles. It integrates with upstream (preform hopper loaders) and downstream (conveyors, fillers) equipment.

  • 4 Cavity: This refers to the mold. The machine has a single mold that contains four individual bottle-shaped cavities. This means it produces four bottles every single machine cycle.

  • PET Blowing Machine: It uses a specific process of heating, stretching, and blowing compressed air to form Polyethylene Terephthalate (PET) plastic, known for its clarity, strength, and gas barrier properties.

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)
Answer: Regular maintenance includes:Daily: Lubrication, air pressure checksMonthly: Mold cleaning, heater inspectionYearly: Servo motor and hydraulic system overhaul
Answer: Yes! We offer turnkey solutions, including:Preform injection machinesBlow moldersConveyors, labelers, fillersQuality inspection systems
Answer: We provide:1–2 years warranty (core parts)24/7 remote supportOn-site technician dispatch (if needed)

The ordering process of PET blow molding machines usually includes demand confirmation, technical negotiation, contract signing, payment arrangement, production and delivery, installation and commissioning, and after-sales service. The following are detailed steps:

PET Blow Molding Machine Ordering Process

Phase Step Details Customer Action Required
1. Inquiry Submit Requirements Provide bottle specs (size, capacity), material (e.g., rPET), automation needs. Fill out RFQ form or share technical specs.
Receive Proposal Supplier recommends machine type (1-step/2-step), configuration, and quote. Confirm feasibility & budget.
2. Order Confirmation Sign Contract Finalize specs, delivery timeline, payment terms (e.g., 30% deposit). Pay deposit (typically 30-50%).
Approve Technical Drawings Review/approve mold designs or samples (threads, dimensions). Sign off or request modifications.
3. Production & Testing Manufacturing Machine and mold production (lead time: 45-60 days). Pay milestone payments as scheduled.
Factory Acceptance Test (FAT) Witness testing (on-site/video) for output, bottle quality. Attend or delegate inspection.
4. Delivery & Installation Shipping Sea/land transport (packed securely with customs documents). Handle local logistics/clearance.
Installation & Training On-site setup by engineers (5-7 days); operator training. Provide utilities (power, air, etc.).
5. Acceptance & After-Sales Final Acceptance Sign after trial production meets specs (1-2 years warranty). Pay balance (10-20%).
After-Sales Support Lifetime tech support; free spare parts during warranty; 24/7 remote aid. Share maintenance records.

Notes:

  • Customization: Special bottle designs or high-speed models may extend lead time.
  • Eco Options: rPET upgrades/energy-saving features must be stated in the contract.
