Semi-automatic tube fillers process around 30–100 tubes per minute. Operators load tubes manually, while the machine handles filling and sealing. This design reduces human error but still requires hands-on work.

Typical specifications include:

  • Fill volume range: 5–500 ml
  • Accuracy: ±2%
  • Power consumption: 2–5 kW
  • Compressed air requirement: 6–8 bar

These systems are affordable, with an initial investment of $15,000–$50,000. The moderate price point makes them ideal for startups, small cosmetic brands, or specialized pharmaceutical packaging machine applications.

Another advantage is flexibility. Semi-automatic tube fillers allow quick product changeovers. Setup time averages 15–30 minutes, so manufacturers can switch between different creams, gels, or ointments without long delays. This makes them a strong choice for companies producing multiple product lines.

2. Fully Automatic Tube Filling Machines

For larger factories, an automatic tube filling machine is the preferred choice. These systems deliver high speed and consistency, processing 200–600 tubes per minute with minimal operator input. The entire process is automated, including tube feeding, filling, sealing, trimming, and coding.

Key performance parameters:

  • Fill accuracy: ±1%
  • Production capacity: 10,000–35,000 tubes/hour
  • Power consumption: 15–25 kW
  • Floor space requirement: 15–25 m²

While the upfront cost is higher, the return on investment usually comes within 18–24 months. That’s because automation reduces labor expenses, boosts throughput, and minimizes waste.

Another benefit of automatic tube filling machines is scalability. They support continuous operation, making them suitable for high-demand industries such as cosmetics, pharmaceuticals, and chemical packaging. These machines also integrate with tube sealing machines and advanced systems like ultrasonic tube sealing for superior results.

Leading suppliers such as KP Filling Machine offer advanced automatic solutions. Our machines are designed to meet strict tube filling operation standards while delivering long-term reliability.

You need to know that proper installation directly impacts performance and machine longevity. Every tube filling machine must meet its technical requirements before commissioning. Skipping steps or using incorrect site conditions often leads to breakdowns, reduced accuracy, or even safety risks. 

Also, professional installation is always recommended to keep warranties valid and to guarantee reliable operation.

Basic Installation Steps

Before bringing a tube filling machine into production, the site must be prepared. Common requirements include:

  • Level concrete floor with a maximum deviation of ±2 mm
  • Electrical supply: 380V/50Hz, 3-phase
  • Compressed air: 0.6–0.8 MPa, dewpoint –40°C
  • Adequate ventilation for cooling and heat dissipation

Automatic systems usually require 3–5 days for full installation and commissioning. This period includes unpacking, positioning, electrical wiring, air connection, and safety checks. 

Semi-automatic models are quicker to set up but still benefit from trained technicians to avoid alignment or calibration errors. KP Filling Machine provide on-site setup services, which save time and reduce the risk of early faults. Our team also trains operators during installation so production can start smoothly.

Calibration and Adjustment

Once installation is complete, calibration ensures accurate filling and proper sealing. For tube filling operations, calibration is done under production-like conditions. The most reliable method is gravimetric testing:

  1. Fill 10 consecutive tubes with the product.
  2. Weigh each filled tube.
  3. Calculate the mean deviation from the target fill.
  4. Adjust servo motor parameters or dosing system settings.
  5. Repeat until accuracy reaches ±1%.

It’s important to control product conditions during testing. Temperature affects viscosity, which impacts how the machine dispenses material. Product temperature should remain stable within ±2°C during calibration. Otherwise, accuracy may drift during operation.

In addition to volume calibration, sealing units also require adjustment. For ultrasonic tube sealing, vibration power and time are fine-tuned. For heat sealing, operators adjust jaw pressure and temperature settings. Proper calibration in both areas ensures consistent quality and reduces rework.

Tube Filling Process

Loading Tubes and Filling Products

In a typical tube filling operation, tubes are loaded into holders. An automatic indexing system rotates them into position. The filling heads inject the product with precision. After filling, the tubes move forward for sealing.

Filling Different Product Types

Different industries deal with a wide range of viscosities, and a cosmetic tube filling machine may be required to fill lotions, gels, or pastes, while pharmaceutical tube filling equipment often handles ointments or medicated creams. 

The dosing system inside the machine adapts to each product type, giving manufacturers the flexibility to switch between products without investing in separate equipment.

Here is a breakdown of how filling parameters change with product type:
