Product Overview
As a CE/FDA-compliant solution, it caters to the rigorous standards of pharmaceutical and cosmetic industries, where accuracy and product integrity are paramount. The machine features a servo-driven piston filler with 0.1–500 mL dosing capability, achieving ±1% filling accuracy even for high-viscosity formulations like creams and gels. Its 20 kHz ultrasonic sealing system creates molecular bonds in tube materials—eliminating thermal stress that can degrade sensitive ingredients like hyaluronic acid and retinol. Constructed with 316L stainless steel contact parts (Ra≤0.8μm polish), it meets GMP requirements, while the PLC-controlled HMI streamlines operations with multi-format changeovers in <10 minutes.
Product Specifications
Features
1. Ultrasonic Sealing Excellence
The ultrasonic transducer generates high-frequency vibrations that create molecular fusion in tube materials— aluminum-plastic composite or plastic—resulting in seals with 50 N/cm tensile strength. Unlike heat sealing, this process operates at low temperatures (≤40°C), preserving heat-sensitive ingredients like vitamin C and CBD that degrade under thermal stress. The sealed seams are resistant to moisture and pressure, withstanding up to 5 bar internal pressure—critical for products like toothpaste and industrial adhesives that may experience squeezing
during use. An integrated seal inspection camera checks each seam for uniformity, rejecting defective tubes at a rate of <0.3%.
2. Precision Filling System
At the heart of the machine is a closed-loop servo piston filler with micro-stepping technology, ensuring 0.01 mL repeatability across 1,000+ cycles. This precision is indispensable for costly formulations like anti-aging serums and prescription ointments, where overfilling wastes resources and underfilling risks regulatory non-compliance. The filler accommodates viscosities from 100–1,000,000 cP, handling everything from thin gels to thick balms, with adjustable filling speeds to prevent splashing or air entrapment. For air-sensitive products, an optional vacuum
degassing system removes entrapped air to <0.1% content, extending shelf life by up to 30%.
3. Smart Process Control
The ultrasonic tube sealer is equipped with an intelligent and easy-to-operate HMI (Human-Machine Interface). It allows setting of sealing time and pressure adjustment; during emergency stop, the HMI automatically records the current parameters, and one-click recovery is available after restart—eliminating the need for reconfiguration. These and other functions reduce errors caused by manual intervention.
Applications
Pharmaceuticals: Fills antibiotic ointments, corticosteroid creams, and sterile ophthalmic gels in tamper-evident tubes.
Cosmetics: Processes lip balms, concealers, and airless foundation tubes with precise dosage control.
Personal Care: Handles sunscreen sticks, hand sanitizers, and hair styling waxes requiring leak-proof seals.
Food Industry: Packages gourmet sauces, honey spreads, and nutritional pastes with food-grade materials.
FAQ
Q: What tube materials are compatible with the machine?
A: It works seamlessly with aluminum-plastic composite, plastic (PE, PP) tubes.
Q: How does ultrasonic sealing compare to traditional heat sealing?
A: Ultrasonic sealing reduces energy consumption by 30% and eliminates thermal degradation of ingredients. It also creates stronger seals (50 N/cm vs. 30 N/cm for heat sealing) and works with heat-sensitive materials like biodegradable plastics that melt under high temperatures.
Q: Regarding the tail-sealing mold, is it necessary to customize it separately according to the different diameters/shapes of the packaging tubes?
A: Yes. The molds required correspond to different diameters and shapes of packaging tubes. Customized molds tailored to specific specifications are necessary to ensure compatibility with your tubes.
Q: Is it easy to clean for tube filling sealing machine?
A: Yes. All connection positions use quick-connectors, which are very easy to disassemble and clean, which meets the hygiene standards of food and cosmetics production.
