Extrusion Blow Molding Machines


Extrusion blow molding machines are essential for manufacturing hollow plastic products like bottles, containers, and tanks. As demand grows, buyers seek reliable equipment from China, the world's leading manufacturer. This guide helps you navigate the market in 2025.


How to Find Reliable Extrusion Blow Molding Machines from China in 2025


Finding trustworthy suppliers requires research. Start with Alibaba's verified suppliers - look for Gold Supplier status and trade assurance. Check factory audits and customer reviews. Request samples to test machine quality before large orders. Attend trade shows like Canton Fair to meet manufacturers in person.


What Buyers Should Know Before Buying Extrusion Blow Molding Machines from China


Understand Chinese pricing structures - cheaper machines may compromise on components. Verify CE certification and warranty terms. Factor in shipping costs and import duties. Consider after-sales support availability in your region. Negotiate payment terms (30% deposit is standard).


Types of Extrusion Blow Molding Machines


Continuous Extrusion Machines

Ideal for high-volume production of small to medium containers (100-5000ml). Operates 24/7 with consistent output. Typical output: 800-1500 bottles/hour.


Intermittent Extrusion Machines

Better for large containers (5-30L) and complex shapes. More precise parison control. Lower output (200-600 units/hour) but higher flexibility.


Accumulator Head Machines

For extra-large containers (30-1000L). Uses stored molten plastic for heavy-duty applications like industrial drums.


Functions and features of Extrusion Blow Molding Machines


Modern machines offer:

  • PLC control systems with touchscreen interfaces
  • Energy-saving servo motors (30-50% less power)
  • Automatic parison control for wall thickness
  • Quick mold change systems (under 15 minutes)
  • Integrated quality inspection systems

Scenarios of Extrusion Blow Molding Machines


These machines produce:

  • Food/beverage containers (milk bottles, juice jugs)
  • Cosmetic packaging (shampoo bottles, cream jars)
  • Automotive fluids containers (oil, coolant)
  • Industrial chemical drums
  • Medical fluid containers

How to Choose Extrusion Blow Molding Machines


Consider:

  1. Production volume needs
  2. Container size range
  3. Material compatibility (HDPE, PP, PVC etc.)
  4. Available factory space
  5. Budget (entry-level starts at $20,000)
  6. Future expansion plans

Extrusion Blow Molding Machines Q & A


Q: What's the typical lifespan of these machines?

A: Well-maintained machines last 10-15 years. Critical components like screws may need replacement after 5-7 years.


Q: How much floor space is required?

A: Small machines need ~50m² including auxiliary equipment. Large systems may require 200m²+.


Q: What's the power consumption?

A: Ranges from 15kW for small machines to 100kW+ for large systems. Servo models cut energy use significantly.


Q: Can one machine handle different materials?

A: Yes, but material changes require thorough cleaning and parameter adjustments.


Q: How many operators are needed?

A: Automated lines may need just 1-2 operators. Manual systems require 3-4 workers.
