Top Accumulator Blow Moulding Machine Manufacturer — Faith Engineering Works

Faith Engineering Works is an accumulator blow moulding machine manufacturer based in Delhi, India, manufacturing machines since 2000. Our Accumulator Head machines are built for larger containers — up to 10 litres — where consistent wall thickness matters most, such as industrial jerry cans, drums, and large containers.

If you’re evaluating an accumulator blow moulding machine, this page explains what makes it different from a standard continuous extrusion machine, when you actually need one, and what to look for in a manufacturer.

Accumulator vs Continuous Extrusion — What’s the Real Difference?

Most blow moulding machines use one of two methods to form the parison (the hollow plastic tube that gets shaped into a container). Knowing the difference helps you pick the right machine for your product.

Continuous Extrusion — The parison is extruded continuously, non-stop, as the machine forms each container. This method works well for small to medium containers with shorter cycle times, and it requires plastic with good melt strength to hold its shape while being extruded. It’s simpler, requires less investment, and is common for machines producing bottles up to a few litres.

Accumulator Extrusion — Instead of extruding continuously, the machine gathers (accumulates) melted plastic in a storage chamber first. When the mould is ready, a piston pushes the accumulated plastic out through the die in one fast, controlled shot, forming the parison almost instantly. This method is used for:

• Larger containers — where a continuous extrusion process would take too long and cause uneven wall thickness
• Thicker-walled products — like heavy-duty drums and industrial containers that need extra strength
• Materials with lower melt strength — which can’t hold their shape well during a slow, continuous extrusion process
• Longer cycle times — where consistent thickness matters more than continuous output speed

This is exactly why accumulator technology is the standard choice for large containers like 10-litre jerry cans, industrial drums, and water containers — the accumulated “shot” of plastic gives far more consistent wall thickness than trying to stretch a continuous extrusion across a large mould.

How an Accumulator Blow Moulding Machine Works — Step by Step

1. Plastic is melted by the extruder screw, same as any blow moulding machine.
2. Melted plastic collects in the accumulator chamber, building up the exact volume needed for the container size.
3. Once enough plastic has accumulated, a piston pushes it through the die head in a single controlled shot, forming the parison quickly and evenly.
4. The parison is clamped inside the mould, and air is blown in to shape the container.
5. The mould opens, the finished container is ejected, and the accumulator begins gathering plastic for the next cycle.

The key advantage is step 3 — because the parison forms in one fast shot rather than a slow continuous stream, wall thickness stays far more even across large or heavy-duty containers.

Faith Engineering Works’ Accumulator Head Machines

We manufacture Accumulator Head blow moulding machines in-house from our facility in Bawana Industrial Area, Delhi, including:

• Auto De-Flashing systems — for a clean finish even on large, heavy-duty containers
• Customised mould configuration — built around your specific container size and shape

Why Choose Faith Engineering Works

25+ Years of Manufacturing Experience — building blow moulding machines, including accumulator systems, since 2000.

In-House Manufacturing — every machine, including the accumulator mechanism, is designed, built, and tested at our own Delhi facility.

Quality Assurance at Every Stage — accumulator systems are checked to confirm consistent wall thickness performance before a machine leaves our facility.

Customised Solutions — accumulator capacity and mould configuration are adjusted based on your specific container size, not offered only as fixed models.

Direct Service & Support — installation guidance and after-sales support for accumulator systems come directly from the team that built your machine.

When Do You Actually Need an Accumulator Machine?

Not every business needs one — here’s a simple way to check:

• If you’re producing containers under 1-2 litres, a continuous extrusion machine is usually sufficient and more cost-effective.
• If you’re producing large containers (5 litres and above), jerry cans, drums, or thick-walled industrial products, an accumulator machine gives you the consistent wall thickness these products need.
• If your raw material has lower melt strength or your product design requires longer cycle times, accumulator extrusion handles this better than continuous extrusion.

Frequently Asked Questions

Q1. What is an accumulator blow moulding machine?
An accumulator blow moulding machine gathers melted plastic in a storage chamber and pushes it out through the die in a single fast shot to form the parison, unlike continuous extrusion machines that extrude plastic non-stop.

Q2. What is the difference between accumulator and continuous extrusion blow moulding?
Continuous extrusion forms the parison as a non-stop stream, suited to smaller containers with shorter cycles. Accumulator extrusion gathers plastic first and releases it in one controlled shot, giving more even wall thickness for larger or thicker-walled containers.

Q3. When do I need an accumulator blow moulding machine instead of a continuous extrusion machine?
You typically need an accumulator machine for containers 5 litres and above, thick-walled industrial products, jerry cans, and drums, where consistent wall thickness matters more than continuous production speed.

Q4. What container sizes does Faith Engineering Works’ accumulator machine produce?
Faith Engineering Works manufactures a 10-litre Accumulator Head machine designed for large industrial containers, jerry cans, and drums.

Q5. Why does wall thickness matter more in accumulator-made containers?
Large or thick-walled containers need even wall thickness for strength and durability. The accumulator’s single controlled shot of plastic distributes more evenly than a continuous stream stretched across a large mould.

Q6. Can Faith Engineering Works customise an accumulator machine for a specific container design?
Yes. Accumulator capacity and mould configuration are adjusted according to the customer’s specific container size and production requirement.

Q7. Does Faith Engineering Works provide support for accumulator systems after installation?
Yes. Since machines are manufactured in-house at our Delhi facility, our team provides direct installation support, operator guidance, and spare parts for accumulator systems.

Q8. How long has Faith Engineering Works been manufacturing accumulator blow moulding machines?
Faith Engineering Works has been manufacturing blow moulding machines, including accumulator systems, since 2000, giving the company over 25 years of experience in this field.
