Ultrasonic Master-Slave Tube Filling & Sealing Machine | Tube-in-Tube Dual Paste Packaging Solution

The ultrasonic master-slave tube filling and sealing machine is a specialized packaging equipment designed exclusively for tube-in-tube (double-layer master-slave plastic tubes). As the cosmetic and pharmaceutical industries continue launching innovative dual-component skincare cleansers, compound ointments and two-phase gel products, ordinary single-tube filling machines can no longer meet production demands. This machine comes with two independent filling channels, which can inject different raw materials into the inner tube and outer tube respectively, realizing one-stop automatic filling and ultrasonic sealing.

Different from traditional hot-air sealing machines, this model adopts localized ultrasonic welding technology. It will not produce overall high-temperature heating, effectively preventing tube deformation and protecting heat-sensitive active ingredients inside cosmetics and medicines. The complete workflow covers automatic tube feeding, color mark positioning, quantitative dual filling, ultrasonic sealing and tail trimming, greatly reducing manual intervention and improving production consistency.

Core Advantages

Dual independent filling channels, completely avoiding cross-contamination between two different materials.
Ultrasonic local sealing, low thermal impact, compatible with heat-sensitive formulas.
PLC touchscreen control with English interface, simple parameter adjustment.
Pneumatic driving structure, stable operation, equipped with “no tube, no filling” safety protection.
Material contact parts adopt SUS304 stainless steel, SUS316L optional, complying with cosmetic hygiene standards.
Flexible customization: filling volume, tube mold and production speed can be adjusted according to customer tube samples.
