High-Precision PET Bottle Blow Molding Machine

Overview

The High-Precision PET Bottle Blow Molding Machine is a state-of-the-art solution designed for producing high-clarity PET bottles for beverages, personal care, and household products. Engineered for precision and efficiency, this machine combines extrusion blow molding and injection stretch blow molding (ISBM) technologies, ensuring uniform wall thickness, superior impact resistance, and dimensional accuracy for bottles (50ml-5L).

Features

Advanced Molding Technology:

ISBM Module: Servo-driven stretch rods and temperature-controlled molds (accuracy ±1°C) produce bottles with uniform wall thickness (±5%) and high clarity (haze ≤1%), ideal for premium beverages.

Extrusion Blow Molding: Dual-layer co-extrusion for barrier bottles (PET/EVOH), reducing oxygen ingress by 70% for shelf-stable juices and sauces.

High-Speed Production:

Output: 5,000-20,000 bottles/hour (500ml), with quick mold changeover (≤20 minutes) via hydraulic clamping system, supporting multi-product runs.

Automatic parison weight control (±0.5g) reduces material waste by 15% compared to traditional blow molders, suitable for lightweight bottle designs (18g-50g).

Precision Engineering:

3D parison programming adjusts wall thickness in real-time for complex shapes (elliptical, handle-equipped), with built-in preform orientation sensors ensuring uniform stretch ratios.

Low-pressure air system (4-6 bar) for gentle bottle ejection, minimizing surface scratches and improving first-pass yield to 99.2%.

Energy & Material Efficiency:

Electric servo drives (100% oil-free) reduce energy consumption by 30% and eliminate hydraulic fluid contamination risks, compliant with ISO 14001.

Scrap recycling system reclaims 98% of production waste, supporting circular economy initiatives for rPET usage.

Application

Ideal for PET bottle manufacturers in diverse industries:

Beverages: 330ml-2L clear PET bottles for soda, water, and juice, with optional anti-UV additives for light-sensitive products.

Personal Care: 100ml-1L lotion bottles and shampoo containers, with embossed designs and tamper-evident neck finishes.

Household Products: 500ml-5L detergent bottles with handle features, ensuring ergonomic design and material efficiency.

The machine integrates with preform feeders and downstream filling lines, forming a seamless PET packaging ecosystem.
