Accumulator Head Technology in Blow Molding Machines: A Deep Dive by Leshan

Blow molding machines have revolutionized the manufacturing industry, offering efficient, scalable, and versatile solutions for producing hollow plastic products. Among the various advancements in this field, accumulator head technology stands out for its ability to handle large and complex products with precision. As a leading blow molding machine manufacturer, Leshan is at the forefront of integrating this technology into its machinery, ensuring optimal performance, energy efficiency, and product quality.


What is Accumulator Head Technology?

Accumulator head technology is a specialized system used in extrusion blow molding machines. It works by accumulating a predetermined amount of molten plastic in a chamber (the accumulator) before rapidly discharging it through a die head to form a parison. This method is particularly beneficial for producing large containers, automotive parts, and industrial components where uniform wall thickness and high structural integrity are crucial.

Accumulator Head Technology in Blow Molding Machines

The accumulator head system offers significant advantages over continuous extrusion systems, especially in terms of controlling material flow, reducing cycle times, and accommodating high-viscosity polymers. Leshan’s blow molding machines equipped with accumulator heads are designed to meet the evolving needs of industries seeking robust and reliable production solutions.

Key Features of Leshan’s Accumulator Head Blow Molding Machines

  • Precision Material Control: The accumulator head allows for accurate measurement and discharge of molten plastic, ensuring consistent parison weight and wall thickness.
  • High Production Flexibility: Leshan machines can handle a wide range of materials, including HDPE, PP, and engineering plastics, making them suitable for diverse applications.
  • Energy Efficiency: The intermittent operation of the accumulator head reduces energy consumption compared to continuous extrusion, contributing to lower operational costs.
  • Enhanced Product Quality: Uniform parison formation minimizes defects and improves the structural integrity of finished products.
  • Customizable Designs: Leshan offers machines with customizable accumulator capacities and die head configurations to cater to specific production requirements.

How Accumulator Head Technology Works

The process begins with plastic resin being melted and conveyed by a screw extruder into the accumulator chamber. Once the desired amount of material is collected, a hydraulic ram pushes the molten plastic through the die head, forming a parison. The mold then closes around the parison, and air is blown inside to shape the product. After cooling, the mold opens, and the finished product is ejected.

This method enables the production of large, thick-walled items that would be challenging to manufacture using other blow molding techniques. Leshan, as a blow molding machine manufacturer, leverages advanced accumulator head designs to ensure smooth and reliable operation, even when processing demanding materials or complex product shapes.

Applications of Accumulator Head Blow Molding Machines

Accumulator head technology is ideal for manufacturing products that require precise control over wall thickness and material distribution. Some common applications include:

  • Industrial drums and barrels
  • Automotive fuel tanks and air ducts
  • Large water storage tanks
  • Outdoor furniture and playground equipment
  • Specialty packaging containers

Leshan’s blow molding machines are trusted by manufacturers worldwide for their ability to produce high-quality, durable products across these and many other sectors.


Comparing Accumulator Head and Continuous Extrusion Blow Molding

Feature Accumulator Head Continuous Extrusion
Production Size Large/Complex Products Small/Medium Products
Wall Thickness Control Excellent Good
Material Range Wide (incl. high-viscosity) Moderate
Cycle Time Shorter for Large Parts Continuous for Small Parts
Energy Consumption Lower (intermittent) Higher (continuous)

As this comparison shows, accumulator head technology is the preferred choice for manufacturers aiming to produce large, high-quality items with precise specifications.
