20-23 Tubes/min Semi-auto Ultrasonic Tube Filler-Sealer for Pharma/Cosmetics

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.

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.
