How to check the performance of a manual paste liquid filling machine?

2025-07-08

Hey there! As a supplier of manual paste liquid filling machines, I often get asked about how to check the performance of these machines. It's a crucial step, whether you're a newbie in the business or a seasoned pro looking to optimize your operations. So, let's dive right in and explore the key aspects of evaluating the performance of a manual paste liquid filling machine.

1. Visual Inspection

First things first, give your machine a good visual once - over. Look for any signs of wear and tear, like loose parts, cracked hoses, or rust. These issues can not only affect the machine's performance but also lead to potential safety hazards. Check the exterior for dents or scratches that might have occurred during transportation or normal use. Make sure all the buttons, switches, and gauges are in place and functioning properly.

A well - maintained machine is more likely to perform at its best. If you notice any damage, it's important to address it right away. You can either repair the parts yourself if you have the skills or contact our support team for assistance.

2. Filling Accuracy

One of the most important performance indicators of a manual paste liquid filling machine is its filling accuracy. To check this, you'll need to conduct a series of filling tests. Start by preparing a batch of the paste liquid you'll be using. Set the machine to fill a specific volume, say 100 ml, and fill a number of containers, at least 10.

After filling, measure the actual volume in each container using a calibrated measuring device. Compare the measured volumes with the set volume. The difference between the set volume and the actual volume is called the filling error. A high - quality manual paste liquid filling machine should have a filling error of less than ±1%. If the error is larger, it could be due to issues such as a clogged nozzle, a malfunctioning valve, or incorrect settings.

3. Filling Speed

The filling speed is another critical factor. You want a machine that can fill containers at a reasonable pace without sacrificing accuracy. To measure the filling speed, time how long it takes to fill a specific number of containers. For example, time how long it takes to fill 50 containers of 50 ml each.

Calculate the average filling time per container. Then, compare this time with the manufacturer's specifications. If the actual filling speed is significantly slower than the specified speed, there could be problems with the machine's pump, the viscosity of the paste liquid, or the operator's technique.

4. Consistency

Consistency is key when it comes to filling. You want each container to have the same amount of paste liquid as the others. To check for consistency, look at the variation in the filling volumes of the containers you filled during the accuracy test. A small standard deviation indicates high consistency.

If you notice a large variation in the filling volumes, it could be because of uneven pressure in the filling system, inconsistent paste viscosity, or improper adjustment of the filling parameters. Make sure to adjust the machine settings as needed to improve consistency.

5. Leakage Test

A leaking machine is not only a waste of product but can also create a messy and unsafe working environment. To perform a leakage test, run the machine for a few cycles without containers. Check for any signs of leakage around the nozzles, valves, and connections.

If you find any leaks, tighten the connections or replace the seals. Sometimes, a simple adjustment can solve the leakage problem. However, if the leak persists, it might be a sign of a more serious issue, and you should contact us for further inspection.

6. Ease of Operation

A good manual paste liquid filling machine should be easy to operate. Check if the controls are intuitive and easy to understand. Can the operator easily adjust the filling volume, speed, and other parameters? Also, consider the ease of cleaning and maintenance.

A machine that is difficult to operate can lead to errors and inefficiencies. If you or your operators are having trouble using the machine, take a look at the user manual or give us a call. We can provide training and support to help you get the most out of your machine.

7. Compatibility with Different Paste Liquids

Manual paste liquid filling machines are often used to fill a variety of paste liquids with different viscosities and properties. To check the machine's compatibility, test it with different types of paste liquids that you plan to use.

Automatic Rotor Pump Filler With Feeder

Some paste liquids might be too thick or too thin for the machine to handle properly. If you notice that the machine has difficulty filling a particular type of paste liquid, it could be necessary to adjust the settings or even consider using a different type of filling mechanism. For example, our Automatic Rotor Pump Filler with Feeder is designed to handle a wide range of paste viscosities.

8. Noise and Vibration

Excessive noise and vibration can be a sign of mechanical problems in the machine. While some level of noise and vibration is normal during operation, if it's unusually loud or intense, it could indicate issues such as loose parts, misaligned components, or a worn - out motor.

To check for noise and vibration, run the machine and listen carefully. If you notice any abnormal sounds or excessive shaking, stop the machine immediately and inspect it. Tighten any loose parts or realign the components as needed.

9. Durability

Durability is an important consideration, especially if you plan to use the machine for a long time. Check the build quality of the machine. Look at the materials used in its construction. A machine made of high - quality materials is more likely to last longer.

You can also check the warranty period offered by the manufacturer. A longer warranty period usually indicates that the manufacturer has confidence in the durability of their product. At our company, we stand behind the quality of our manual paste liquid filling machines and offer a comprehensive warranty.

10. Comparing with Similar Machines

If you have access to other manual paste liquid filling machines, it can be helpful to compare their performance with yours. This can give you a better idea of how your machine stacks up against the competition.

Look at factors such as filling accuracy, speed, consistency, and ease of operation. You might find that there are areas where your machine can be improved or that it outperforms other machines in certain aspects.

In conclusion, checking the performance of a manual paste liquid filling machine is a multi - step process that involves visual inspection, testing filling accuracy and speed, checking for consistency and leakage, evaluating ease of operation, and considering other factors like compatibility, noise, durability, and competition. By regularly checking the performance of your machine, you can ensure that it operates at its best and meets your production needs.
