Automatic Tube Filling-Sealing Monoblocs
LOCUS ROBOTICS Group manufactures, supplies, commissions, and deploys automatic tube filling machines for plastic and aluminum tubes. Both automatic fillers and semi-automatic monoblocs feature rotary indexing design — enabling fully automated processing with minimal operator intervention while ensuring consistent end-product quality.
Locus Robotics’ automatic monoblocs deliver integrated tube filling, capping, and sealing in one synchronized operation. Engineered for pharmaceutical creams, cosmetic gels, and industrial adhesives, our servo-driven systems handle aluminum crimping and laminate heat-sealing without tool changeovers – achieving outputs up to 400 tubes/minute with ±0.5% fill accuracy.
| Tube Type | Sealing Mechanism | Key Components | Output |
|---|---|---|---|
| Extruded Plastic | Thermal sealing (copper-heated jaws) | Mechanical crimping units | Up to 1,200 tph |
| Laminate | Ultrasonic sealing (generator-based) | Pneumatic clamping systems | Up to 1,200 tph |
| Aluminum | Precision crimping | Steel rollers with servo drive | Up to 1,200 tph |
Standard monoblocs process either plastic OR aluminum tubes due to fundamentally different tooling requirements.
Laminate Tubes
Ultrasonic sealing preferred for multi-layer/foil-lined constructions
60% faster cycle times vs thermal methods for thick-walled tubes
Extruded Plastic Tubes
Copper-heated jaws ensure consistent thermal sealing
Aluminum Tubes
Dual crimping options: Servo-driven rollers or pneumatic compression heads
Standard: Single-nozzle rotary systems (1,200 tubes/hour)
Premium: Quad-nozzle configurations with:
Dual tube orienters
High-capacity automated hoppers
Integrated rejection systems
Automatic models feature tube orientation systems absent in semi-automatic units.
