How to adjust the sealing pressure of a tube filling sealing machine?

2025-07-01

Adjusting the sealing pressure of a tube filling sealing machine is a crucial process that directly impacts the quality and integrity of the sealed tubes. As a reputable supplier of tube filling sealing machines, I understand the significance of this adjustment and am here to guide you through the process.

Understanding the Importance of Sealing Pressure

The sealing pressure of a tube filling sealing machine plays a vital role in ensuring a secure and leak - proof seal on the tubes. If the pressure is too low, the seal may not be strong enough, leading to product leakage during storage or transportation. This can result in product loss, damage to packaging, and potential customer dissatisfaction. On the other hand, if the pressure is too high, it can cause deformation of the tube, damage to the sealing mechanism, and even affect the overall appearance of the product. Therefore, finding the optimal sealing pressure is essential for the efficient operation of the machine and the quality of the final product.

Factors Affecting Sealing Pressure

Several factors can influence the ideal sealing pressure for a tube filling sealing machine.

Tube Material: Different tube materials, such as plastic, aluminum, or composite materials, have different physical properties. For example, plastic tubes are more flexible than aluminum tubes. So, they may require a different sealing pressure. Plastic tubes can withstand a certain range of pressure without cracking, while aluminum tubes are more rigid but can be dented if the pressure is excessive.
Tube Thickness: Thicker tubes generally need higher sealing pressure to achieve a proper seal compared to thinner tubes. The extra material in thicker tubes requires more force to bond the layers together effectively.
Product Viscosity: If the product being filled into the tubes is highly viscous, it may push against the sealing area during the sealing process. In such cases, a higher sealing pressure might be needed to counteract this force and create a reliable seal.

Steps to Adjust the Sealing Pressure

Refer to the Machine Manual: The first step in adjusting the sealing pressure is to consult the machine's manual. Our tube filling sealing machines come with detailed instructions on how to access the pressure adjustment settings. The manual will also provide the recommended pressure range based on different tube materials and product types.
Prepare the Machine: Before making any adjustments, ensure that the machine is turned off and unplugged for safety reasons. Remove any tubes that are currently in the machine and clean the sealing area to remove any debris or residue that could affect the sealing process.
Locate the Pressure Adjustment Mechanism: Depending on the model of our tube filling sealing machine, the pressure adjustment mechanism can be in different locations. It could be a screw, a knob, or a digital control panel. For older models, it might be a mechanical screw that you can turn clockwise to increase the pressure and counter - clockwise to decrease it. Newer models often feature a digital control panel where you can input the desired pressure value directly.
Make Small Adjustments: When adjusting the pressure, it's important to make small changes at a time. Start with a low pressure setting and gradually increase it. After each adjustment, run a test seal on a few tubes. Check the quality of the seal by visually inspecting it for any signs of leakage, uneven sealing, or tube deformation.
Test the Seals: After making an adjustment, fill a few tubes with the product and run them through the sealing process. Inspect the seals carefully. If the seal is too weak and shows signs of leakage, increase the pressure slightly and repeat the test. If the tube is deformed or the seal looks damaged, decrease the pressure.
Record the Settings: Once you have found the optimal sealing pressure, record the settings. This will be useful for future reference, especially if you need to switch between different tube materials or product types.

Using Our Ultrasonic Paste Tube Filling Sealing Machine

Our Ultrasonic Paste Tube Filling Sealing Machine offers advanced features for precise sealing pressure adjustment. The ultrasonic technology used in this machine provides a more consistent and reliable seal compared to traditional methods. The digital control panel allows for easy and accurate pressure adjustment, and it also has a memory function to save your preferred settings.

Troubleshooting Common Issues

Inconsistent Seals: If you notice that some tubes have good seals while others don't, it could be due to uneven pressure distribution. Check if the sealing jaws are properly aligned. You may need to adjust the alignment screws to ensure that the pressure is evenly applied across the sealing area.
Over - Sealing or Under - Sealing: Over - sealing, where the tube is deformed or damaged, can be caused by excessive pressure. Under - sealing, with leakage or weak seals, is usually due to insufficient pressure. Go back to the pressure adjustment steps and make the necessary changes to correct these issues.

Importance of Regular Maintenance

Regular maintenance of the tube filling sealing machine is crucial for maintaining the accuracy of the sealing pressure. Over time, the components of the machine can wear out, which can affect the pressure adjustment. We recommend regular lubrication of the moving parts, checking for loose screws or bolts, and replacing any worn - out parts as soon as possible.
