tube filling and sealing machine

Choosing the correct sealing configuration depends directly on your material traits and formulation sensitivities:
• Hot Air Sealing: Utilizes a specialized heating element to blow high-temperature air inside the tube tail matrix, melting the inner plastic layer right before mechanical jaw compression. It provides a highly premium aesthetic finish at rapid speeds.
• Ultrasonic Sealing: Employs high-frequency acoustic vibrations to generate localized frictional heat precisely at the molecular bonding interface. Because it generates minimal ambient heat, it is exceptionally energy-efficient and ideal for heat-sensitive formulations (e.g., active bio-pharma gels, complex vitamins). It can also successfully bond through slight product residues.

URMACHINE systems are engineered for high substrate flexibility, seamlessly managing:
• Plastic Tubes: Monolayer or multi-layer PE, PP, and PET configurations.
• Laminated Tubes: Aluminum Barrier Laminates (ABL) and Plastic Barrier Laminates (PBL) used extensively for cosmetics and toothpaste.
• Aluminum/Metal Tubes: Pure aluminum sleeves requiring specialized mechanical crimping rather than thermal bonding.

Our filling configurations are customized based on the rheology and flow traits of your product:
• Piston Filling: Driven by high-precision servo systems, this is ideal for highly viscous products (creams, heavy ointments, dental pastes). For ultra-thick compounds, we integrate a product hopper with an active mixing/agitating mechanism and a heated water-jacket to temporarily lower viscosity for smooth delivery.
• Peristaltic Pump & Rotary Valve Filling: Best suited for low-viscosity liquids, oils, and sterile solutions. These are combined with specialized pneumatic anti-drip nozzles to eliminate splashing during high-speed production indexing.
• Auger/Screw Filling: Specially adapted for semi-solid compounds or high-density powders.

Production throughput scales accurately with your automation tier:
• Semi-Automatic Mode: 10–30 tubes/minute (Manual loading, automated filling/sealing).
• Standard Automatic Mode: 30–80 tubes/minute (Fully integrated rotary indexing system).
• High-Speed Rotary System: 80–200+ tubes/minute (Dual-nozzle configurations designed for continuous 24/7 manufacturing plants).

Yes. Our standard standard dosing pumps span filling volumes from 3 mL up to 300 mL. For packaging lines requiring specialized heavy-capacity fills exceeding 250 mL, custom-engineered dosing cylinders and oversized tube holders are available upon request.

Root Causes: Substandard product levels within the hopper causing air pocket entrapment (cavitation); inconsistent hopper agitator RPM; or worn check-valves and dosing pump O-rings inducing pneumatic back-leakage.
Solutions: Calibrate the high/low level sensors to ensure material volume consistently stays above 1/3 of the hopper capacity. Replace the dosing pump's internal O-rings, and adjust the servo travel velocity parameters via the HMI to optimize the volumetric dosing profile.

Root Causes: High cohesive properties in the formula causing structural tailing, or inadequate pneumatic vacuum suck-back pressure preventing the cut-off valve core from sealing tightly.
Solutions: Increase the vacuum suck-back duration and intensity thresholds directly in the HMI parameters. For highly cohesive materials, activate the thermal jacket and agitation loops to lower viscosity. Clean the nozzle assembly and replace any degraded rubber valve gaskets.

Root Causes: The injection nozzle fails to penetrate deeply enough into the tube substrate, causing top-down product collision, or the initial filling velocity profile is set too high.
Solutions: Adjust the mechanical cam settings or modify the servo parameters to activate a precise "Bottom-up Filling" mechanism. Ensure the nozzle lowers completely to the bottom of the tube before product discharge and ascends in perfect synchronization with the rising liquid level.

Root Causes: Scorching and distortion stem from excessive hot air temperatures or prolonged air blow cycles. False welding and leaks are caused by low thermal input, insufficient mechanical jaw pressure, or sealing zone inner walls contaminated by product drips.
Solutions: Fine-tune the hot air thermal profile (typically between 180°C and 350°C, depending on the tube's polymer matrix). Verify that the industrial water chiller is running correctly, as sealing and crimping jaws require consistent chilled loops to lock the tail shape. Resolve any filling nozzle drips to ensure a completely clean sealing zone.

Root Causes: Excessive metal brittleness or poor material annealing from the tube supplier; asymmetrical mechanical pressure exerted by the crimping hands; or worn-out folding tools.
Solutions: Partner with tube vendors providing certified ductile, well-annealed aluminum components. Calibrate the mechanical crimping arms' travel thresholds and spring-loaded pressure balances. Inspect the folding blades for micro-notches or uneven mechanical alignment.

Root Causes: Blunt guillotine trimming blades; an excessive tolerance gap between the active cutting edge and the stationary die counter-part; or loose tube cups causing indexing displacement.
Solutions: Remove the trimming blade set for professional sharpening or replace the blades. Readjust cutting clearances precisely using a feeler gauge. Check for and secure any loose tube holder cups on the rotary turntable carousel.

Root Causes: Insufficient contrast ratios between the printed eye mark and the tube body color; dust or paste film clouding the photoelectric lens; or asynchronous indexing speeds from the orientation motor.
Solutions: Clean the optical sensor lens surface using isopropyl alcohol. Re-teach the photoelectric amplifier sensitivity limits and adjust the gain threshold value within the PLC system. Ensure tube artwork integrates high-contrast registration marks (e.g., dark blue or black eye marks on solid white backgrounds).

Root Causes: Tubes becoming ovalized or flattened due to improper warehouse stacking conditions, or feed chute guide rails not properly adjusted for specific tube batch dimensions.
Solutions: Audit inventory storage parameters to eliminate excessive stacking weight. Micro-adjust the internal width of the feed chute guide rails, maintaining a standard clearance gap of approximately 1mm to guarantee smooth, unhindered down-feed movement.

All URMACHINE systems engineered for pharmaceuticals and high-end cosmetics adhere strictly to GMP guidelines:
• Product contact components are fully machined from premium 316L stainless steel.
• Integrated Clean-in-Place (CIP) and Sterilize-in-Place (SIP) frameworks allow automated flushing and sanitization of dosing pumps, hoppers, and product transfer lines without dismantling the assembly, drastically reducing downtime and eliminating cross-contamination risks.

To transition to a different tube length or diameter, the following changeover components are required:
• Tube Holders/Cups: Swapped on the main rotary indexing turntable to match the new tube diameter.
• Filling Nozzles: Sized appropriately to fit cleanly within the inner neck dimensions of the new tube sleeve.
• Sealing Jaws/Orientation Sleeves: Adjusted or replaced to match the specific width and tail-sealing profile.

Yes, URMACHINE tube fillers feature integrated coding blocks embedded within the sealing/crimping jaws. During the final thermal press or mechanical fold, steel character matrices mechanically emboss the tube tail with:
• Batch/Lot Numbers
• Production & Expiration Dates
• Traceability Codes
Additionally, secondary systems can be fitted with industrial Inkjet or Laser printing extensions if complex barcodes or QR codes are required.
