Meta Description: Looking for a Jerry Can Blow Molding Machine? I’ll walk you through how these machines work, the key features to look for, and how to choose the right one for your production line. Let’s find the best fit for your needs.
Введение
If you’re in the business of making plastic jerry cans for lubricants, chemicals, or water, you know how important the right equipment is. Getting it wrong means wasted material, slow production, and a hit to your bottom line.
My name is Slany Cheuang, and I’m a technical sales manager at Lekamachine. I spend my days talking to people just like you about their production needs.
A jerry can blow molding machine is usually a type of extrusion blow molding machine. It’s designed to make strong, hollow plastic parts. In this guide, I’ll break down everything you need to know before you invest. We’ll keep it simple and straightforward.
The Core Technology: How Extrusion Blow Moulding (EBM) Works
Let’s get into how these machines actually work. The idea is pretty simple. I like to think of it in a few basic steps.
- Plastication: The machine takes solid plastic pellets, usually HDPE, and melts them down into a thick, molten liquid.
- Parison Formation: The machine pushes this melted plastic through an opening, forming a hot, hollow tube of plastic. This tube is called a parison. Think of it like a giant, soft plastic straw hanging down.
- Molding: A two-part mold, shaped like your jerry can, closes around the parison and pinches the bottom shut.
- Blowing: A pin is inserted and blows compressed air into the parison. This forces the soft plastic to expand outwards, pushing it against the cold walls of the mold.
- Охлаждение и извлечение: The plastic cools and hardens into the final shape. The mold opens, and your finished jerry can is ejected. Any extra plastic (flash) is trimmed off, and the cycle repeats.
Why EBM is the Ideal Choice for HDPE Jerry Cans

So, why is this specific method the go-to for making jerry cans? It comes down to a few key reasons.
- Perfect for HDPE: EBM and High-Density Polyethylene (HDPE) work together perfectly. HDPE is the material of choice for its strength, chemical resistance, and low cost. It’s used for everything from 0.1L to 20L containers.
- Strong, Seamless Containers: The can is made from one continuous tube of plastic, so there are no seams on the sides. This makes the product strong and leak-proof—a must-have for passing качество checks like the UN drop test.
- Efficient for Mass Production: EBM machines are built for continuous, 24/7 operation with high output. This is ideal for mid-to-large converters or the in-house plants of major brands.
- Customization for Performance & Savings: The technology allows for advanced features like multi-layer extrusion. This can add a barrier layer, improve performance, and even reduce the total amount of plastic needed, directly cutting resin costs.
How to Choose the Right Jerry Can Machine in 2025: A Buyer’s Checklist
Choosing a machine is a major investment. You’re not just buying equipment; you’re investing in your production line’s future.
To help you make the right call, use this checklist to ask yourself and any potential supplier the right questions.
- What is your required output? Think about volume. Do you need to run 24/7 or only during seasonal peaks? How many cans do you need per hour? This determines the machine’s speed and the number of mold cavities required.
- What are you making, exactly? The size and weight (e.g., 1L bottles vs. 20L jerry cans) will determine the machine model. For chemical containers, you might need a multi-layer machine to meet safety standards for UN dangerous-goods approval.
- How much automation do you need? Skilled labor can be a major cost. A fully automatic machine can handle de-flashing (trimming) and in-mold labeling. A semi-automatic machine may be a better fit for your budget.
- What about energy costs? With energy prices being a concern, ask about power consumption. Modern, energy-efficient motors can significantly lower your long-term operating costs.
- How long are you willing to wait? This is a big one. Ask about the delivery time. The lead time for some European machines can be over 10 months. At Lekamachine, our standard delivery is 60 to 90 days. This can have a huge impact on your business.
- What happens after the purchase? Good after-sales support is crucial. Does the supplier offer setup, operator training, and remote diagnostics? This is vital if you’re setting up a new line or have a small technical team.
Key Features to Look For in a Jerry Can Machine
When looking at specifications, the jargon can be overwhelming. Here are the key features I always tell clients to pay close attention to.
- Multi-Layer Capability Some machines can co-extrude containers with multiple layers. This can save money by reducing the use of expensive virgin plastic. For industrial drums, you might need six or more layers for dangerous goods approval. It’s also key for using sustainable materials like post-consumer resin (PCR).
- Energy Efficiency A machine is a long-term investment, and its power consumption affects your bottom line. Look for energy-saving features like modern, efficient motors (IE4 motors) that cut down on electricity bills.
- Shot Size Shot size is the maximum amount of plastic the machine can push out in one cycle. For small bottles, you need a smaller shot size. For large parts like 250L chemical drums, you’ll need a very large shot size, sometimes over 30 kg. Our TITAN Series is engineered for these large-capacity products.
- Quick Mold Changes If you produce many different products, you can’t afford long downtime. For businesses that run many short jobs, flexibility is crucial. Look for features that allow for quick mold changes and automatic deflashing to make your operation more efficient.
European vs. Chinese Machines: An Honest Comparison
Delivery 90day
This is a conversation I have all the time. For many years, European machines were seen as the gold standard for качество.
But the industry has been changing.
Today, many businesses are open to buying Chinese machines, but with two important conditions: the cycle time has to be just as good as their European peers, and local service must be available. This is especially true in emerging markets, where the price-to-performance ratio and quick delivery are highly valued.
The biggest practical difference is often the wait. The lead time for European machines can be over 10 months. That’s a long time to wait to start production.
At my company, Lekamachine, our standard delivery time is 60 to 90 days. That difference can be a huge advantage. To prove performance, we offer virtual factory tours and run tests using a client’s own plastic resin.
