Oil leakage is one of the most common—and most frustrating—issues that operators encounter when using a lamination machine.You walk into your workshop, everything looks fine, and suddenly—there it is. A shiny pool of oil underneath your machine. But before you panic or call a technician, take a deep breath. In most cases, the problem is simple, and you can fix it yourself once you know where to look.
Today, let’s break down the three key areas to check first when your lamination machine starts leaking oil—and how to get it back in perfect working condition.
1. The Glue Roller – Check the Heat Transfer Oil
If you notice oil leaking near the glue roller, don’t confuse it with adhesive—it’s actually heat transfer oil. This oil circulates inside the roller to maintain consistent heating, ensuring smooth film lamination.
👉 Spot to check: The rotating joint of the heating pipe.
Over time, the seal in this joint can loosen or harden due to temperature cycling, leading to oil seepage. Simply tightening or replacing the seal usually fixes the problem. Regular inspection of your Automatic Lamination Machine can prevent heat transfer oil leaks before they cause downtime.
2. The Screw Holes – Don’t Forget the Threadlocker
If you find oil slowly seeping from the back of your glue roller, take a closer look at the screw holes. The likely culprit? You forgot to use threadlocker or Teflon tape when assembling. Without these, the oil finds micro-gaps and starts to escape under pressure.
It’s an easy fix—just reassemble the screw with the right sealing material. This simple step can prevent recurring leaks in both Semi-Automatic Lamination Machine and Cold Glue Lamination Machine models.
3. The Oil Tank – Burn Out the Moisture
Sometimes the oil leaking from your machine isn’t from the roller or pipe—it’s from the yellow oil tank. Don’t panic. That’s not a broken part; it’s just condensation inside the tank turning into water droplets mixed with oil.
The solution? Burn off the moisture by heating the tank slowly for 30–60 minutes. Once the water evaporates, the leak should disappear. This is a common maintenance step for many lamination machine models, especially when they’re used in humid environments.
4. Industry Analysis: Why Oil Leaks Happen More Often Now
As lamination machines evolve toward higher precision and temperature control, they rely on more complex oil circulation systems. These systems improve performance—but they also demand better sealing and maintenance practices.
Below is a quick analysis of key trends shaping the global lamination equipment industry:
| Parameter | Current Trend | Expected Growth (2025–2030) | Key Driver |
|---|---|---|---|
| Automation Level | Medium to High | +45% | Demand for consistency & speed |
| Use of Heat Transfer Systems | Rapid Increase | +50% | PUR adhesive and advanced heating rollers |
| Maintenance Cost per Machine | Stable to Rising | +20% | More precision components |
| Failure Cause: Oil Leaks | 15–20% of all issues | Slight decline | Better sealing materials |
| Market Size (Global Lamination Machinery) | USD 1.2 Billion | USD 1.8 Billion | Growth in decorative panel industry |
With rising adoption of PUR and eco-friendly adhesives, Automatic Lamination Machines and Cold Glue Lamination Machines are becoming standard in high-end furniture production. However, preventive maintenance is crucial—oil leakage can impact temperature stability, surface quality, and adhesive curing.
5. How to Prevent Oil Leaks in the Future
Regular Seal Inspection – Replace seals every 6–12 months depending on usage.
Use Threadlocker on All Screws – Especially on heating elements and roller mounts.
Avoid Overheating – Maintain operating temperature between 120–150°C for consistent oil viscosity.
Clean the Roller Frequently – Adhesive residue can trap heat and accelerate seal wear.
Drain Condensation from the Tank – Especially in humid workshops or seasonal weather changes.
These habits will extend the lifespan of your Semi-Automatic Lamination Machine and keep your production line running without messy surprises.
6. Frequently Asked Questions (FAQ)
Q1: Why does my lamination machine keep leaking after I change the seals?
It’s likely the joint was overtightened, damaging the new seal. Always follow torque guidelines and test for leaks with low pressure first.
Q2: Can I use normal engine oil instead of heat transfer oil?
No. Only use heat transfer oil rated for high temperature systems. Regular oil breaks down at lamination temperatures and can clog your system.
Q3: What’s the difference between a Cold Glue Lamination Machine and an Automatic Lamination Machine?
The Cold Glue Lamination Machine uses water-based adhesive and is ideal for paper or film applications at room temperature. The Automatic Lamination Machine uses heat and pressure for continuous, high-speed production—best for wood or PVC films.
Q4: How can I identify whether the oil leak is from the glue roller or the tank?
If it’s clear or light-colored, it’s likely heat transfer oil from the roller. If it’s darker and viscous, it may be hydraulic oil from the tank or system line.
