How to choose a tube filling machine for pharmaceutical creams

Introduction

As winter sets in and the temperatures drop, a daily layer of face cream becomes your best defense against the cold. But have you ever paused to wonder how each tube of cream ends up so perfectly filled? From precise dosing to the crisp printing of the company name and production date, the process behind getting that cream into the tube is a fascinating blend of efficiency and precision. Modern tube filling machines make this possible, combining advanced automation, high-speed sealing, and intelligent control systems to ensure every tube meets strict quality standards. These machines not only handle delicate creams with care but also maintain consistency, hygiene, and speed—turning what seems like a simple product into a marvel of engineering.

1.What Is a Tube Filling Machine?

A tube filling machine is equipment designed to fill tubes with products such as liquids, gels, pastes, or creams. These machines are widely used for items like hand lotion, shampoo, paint, and even food products like icing.

Before tube filling equipment existed, operators had to load each tube by hand—spooning or squeezing product into the opening one by one, which was slow and messy. Modern tube filling machines completely changed the process, making tube filling fast, clean, and highly efficient.

1.1 How It Works

While different models vary, most tube filling machines follow these steps:

Tube loading – Either manually or automatically, tubes are placed into holders.

Tube orientation – The machine locates the tube’s eye mark to ensure correct positioning.

Filling – A dosing system injects a precise amount of cream into each tube.

Sealing – Depending on machine type, tubes are sealed by heat, ultrasonic, or hot air.

Trimming and coding – Excess edges are trimmed and batch codes are printed.

Discharge – Finished tubes exit to a conveyor or collection tray.

Tube filling machines take over the entire filling process, making it fast, consistent, and ideal for handling thousands of tubes. Here’s how the workflow typically looks:

Empty tubes are fed into the machine—either automatically or by hand.

The machine orients the tubes so the open ends face upward for accurate filling.

Depending on how thick or fluid the product is, the system uses the appropriate filling method to dispense the exact required amount.

After filling, the tube is securely sealed to prevent leaks or spills. Sealing can be done through heat, ultrasonic technology, or mechanical pressure.

Additional steps—like capping, labeling, or secondary packaging—can be added to the process as needed.

Finally, the filled and sealed tubes exit the machine, typically onto a conveyor or robotic arm, and move on to boxing.

These machines handle tube after tube through multiple automated stages, ensuring precise filling volumes and strong, consistent seals—eliminating the mess and inconsistency of manual filling.

2.Types of Tube Filling Machines for Pharmaceutical Creams

Tube filling machines come in several configurations depending on automation level and production design.

3. Comparison of Semi-Automatic & Fully Automatic Tube Filling Machines

When you’re just starting to fill tubes, one of the biggest decisions is whether to go with a fully automatic machine or a semi-automatic one. Figuring out which level of automation fits your workflow can feel a bit confusing at first!

So, we’ve put together a helpful walkthrough that compares both types across several key points. By the time you finish, you’ll have a clear picture of which option suits your production needs best. Let’s get started!

Output Needs

Fully automatic tube fillers are built for speed. They can pump out thousands of tubes per hour, making them ideal for large-scale factories that need to fill huge volumes every day.

Semi-automatic machines work at a more modest pace — usually a few hundred tubes per hour — and require some operator involvement. They’re a great fit for smaller businesses, short production runs, or testing new products.

Labor Costs

Since fully automatic machines run with minimal human input, companies can significantly cut down on labor expenses. You typically only need a couple of operators to handle refilling materials and basic maintenance.

Product Variety

Fully automatic fillers can easily manage different product types — thick, thin, creamy, or textured. Switching from one formula to another is quick and simple.Semi-automatic machines are better suited for companies with fewer product variations. Regular changeovers can be time-consuming and aren’t as convenient.

Investment Budget

Fully automatic fillers come with advanced sensors, controls, and servo systems, so the upfront cost is higher. Installation and integration also add to the investment.

Semi-automatic machines use simpler components, making them more budget-friendly and easier to get up and running for companies with tighter budgets.

Changeover Time

With full automation, changing tube sizes is incredibly fast — you can swap sizes in just minutes without interrupting production.

On semi-automatic equipment, changeovers take longer because parts need to be physically swapped. During this time, the line has to stop completely, which can slow down operations.

4.The Operation Process of Test Tube Filling Machines

Testing a tube filling machine is critical before full-scale production. The process typically involves:

Setting up the machine with a sample product and tube type.

Running the machine at low speed to check for proper filling, sealing, and coding.

Measuring the output to ensure dosing accuracy.

Checking the quality of seals, trimming, and batch codes.

Adjusting machine parameters such as filling volume, sealing temperature, and conveyor speed for optimal performance.

Regular testing ensures consistent quality, avoids wastage, and verifies compliance with production standards.At present, automated test tube fillers can process up to 1,680 tubes per hour, with computerized controls ensuring accurate flow into each and every tube
