Semi-Automatic Aluminum Tube Filling & Sealing Machine
Product Overview
This semi-automatic aluminum tube filling and sealing machine is an all-in-one packaging solution for aluminum collapsible tubes. It integrates precision quantitative filling, multi-mode mechanical sealing, batch coding and automatic discharging. Adopting pneumatic-mechanical linkage control and a 16-station rotary worktable, the machine requires only manual tube loading. All subsequent procedures, including positioning, filling, sealing and coding, are completed automatically. The equipment is suitable for pastes, creams, gels and low-viscosity fluids. All material-contact parts adopt 316 food-grade stainless steel, fully complying with GMP standards and hygiene specifications for food, pharmaceutical and cosmetic industries. Featuring stable operation, intuitive control and high cost performance, it is an ideal choice for small and medium-sized manufacturers for mass production, new product trials and customized batch production.
Core Advantages
1. Precise & Controllable Filling
Equipped with a volumetric filling system and high-precision metering pump, the machine supports fine filling adjustment to effectively prevent material overflow and underfilling. It maintains a stable filling accuracy of ±1% and offers multiple optional filling ranges: 5–50 ml, 10–100 ml, 15–150 ml, 20–200 ml and 30–300 ml, with one range provided as standard. These versatile specifications fit aluminum tubes of different capacities and application needs. With stable metering performance and excellent repeatability, the machine ensures consistent fill volume and uniform product quality for every batch. Its production speed is adjustable from 10 to 40 tubes per minute. Operators can adjust the speed according to material viscosity and filling volume, balancing high production efficiency and precise filling results for both small-batch trials and continuous mass production.
2. Firm & Aesthetic Sealing
The machine adopts a purely mechanical, heat-free folding sealing system that perfectly adapts to the physical characteristics of pure aluminum tubes. It effectively avoids metal rebound and sealing gap leakage. The default process is single-direction 2-fold sealing, with optional 3-fold sealing and saddle folding available for different packaging requirements. Operators can switch sealing modes by adjusting mechanical structures or replacing dedicated jigs. Three mainstream folding processes meet diverse standards for sealing tightness and appearance. Supported by high-precision photoelectric positioning sensors, the machine delivers accurate sealing positioning, smooth wrinkle-free fold lines, and firm, crack-proof, leak-proof sealing results, improving product qualification rate and overall packaging quality.
3. Hygienic & Multi-Industry Adaptability
All parts in contact with materials are made of high-quality 316 stainless steel, featuring corrosion resistance, no residue retention and easy cleaning. The dead-corner-free design allows quick disassembly and thorough cleaning, simplifying daily maintenance. Fully compliant with GMP and industrial hygiene standards, the machine is applicable for cosmetics, pharmaceutical ointments, daily chemical products, industrial adhesives and food pastes. It prevents cross-contamination and odor transfer between different materials, adapting well to various clean and dust-free production environments.
4. User-Friendly & Durable
The machine is equipped with a mature PLC control system and intuitive touchscreen HMI. It supports visual parameter setting, one-key start/stop and real-time fault alarming. The simple operation logic requires no professional training, greatly lowering the operating threshold. The 16-station rotary worktable runs smoothly with low noise. Core transmission components adopt wear-resistant hardening treatment, ensuring stable long-term operation, low failure rate and extended service life for continuous industrial production.
5. Cost-Effective & Versatile Production
Compared with fully automatic packaging equipment, this semi-automatic machine achieves an excellent balance between production efficiency and investment cost. It features a compact footprint, simple installation and convenient commissioning. The equipment supports flexible production switching for small-batch trials, medium-volume production and multi-specification runs. Its strong versatility reduces enterprise capital investment and daily operating costs, providing a stable, cost-effective packaging solution for small and medium-sized production lines.

Applicable Materials & Industries
This machine is specially designed for products that require aluminum collapsible tube packaging. Aluminum tubes feature excellent oxygen barrier, light-shielding performance and flexible squeezability. They are irreplaceable for oxygen-sensitive, light-sensitive and long-shelf-life paste and cream products, where plastic tubes cannot meet packaging requirements. The equipment fully matches the packaging standards of mainstream aluminum tube products across various industries. Typical applicable products are as follows:
● Cosmetics: hair dye paste, hair removal cream, bleaching cream, exfoliating cream, and other oxygen-sensitive skincare products that require exclusive aluminum tube packaging;
● Pharmaceuticals: medical ointments, anti-inflammatory creams, burn creams, hemorrhoid ointments, and other topical medicinal gels;
● Daily Chemicals: toothpaste, shoe polish, and metal polishing paste;
● Chemical Industry: sealants, pigment pastes, instant adhesives, and AB glue paste;
● Food Industry: honey paste, fruit jam, and baking cream auxiliaries.
With strong industry adaptability and high versatility, the machine fully meets standardized mass-production packaging requirements for aluminum tube products.
Working Process
Operators manually place aluminum tubes into the fixtures of the 16-station indexing disc. The mechanical transmission system drives the rotary table for automatic indexing and precise positioning. After photoelectric detection verifies correct tube placement, the machine automatically starts precision filling. Upon filling completion, the equipment performs multi-mode tube sealing, including standard single-direction 2-fold sealing, and optional 3-fold sealing and saddle folding. Finished products are automatically discharged after processing. The whole process only requires manual tube loading. All core procedures are fully automated, ensuring stable operation, standardized processing and consistent high production efficiency.
