Aluminum Tube Filling and Sealing Machine

This page covers an aluminium-tube filling and folding configuration. Plastic and laminate tubes normally require a different sealing system, such as hot air or ultrasonic energy, plus different tooling. If several tube materials are planned, provide samples and drawings so the required machine architecture can be reviewed rather than assuming one closure station covers all materials.

Viscosity at filling temperature, yield behaviour, particulates, air sensitivity, stringing, hopper residence time, pump and seal compatibility, nozzle diameter, cutoff, and dose range all matter. A heated or agitated hopper and bottom-up filling may be appropriate, but these are configuration decisions that should be proven with a representative product trial.

A photoelectric sensor can detect a suitable registration mark and rotate the tube to the required position before filling and folding. Artwork contrast, print consistency, tube reflectivity, mark location, and allowable orientation tolerance should be evaluated with production-intent tubes.

Check fold sequence and dimensions, tail cleanliness, code position and legibility, leakage or closure integrity using the agreed method, cosmetic damage, orientation, fill weight, and rejected conditions. The protocol should state the tube supplier, product or substitute, speed, run duration, and sample size.

Provide discharge orientation, tube dimensions, target sustained rate, buffer requirement, transfer height, coding inspection, reject handling, and carton-loading method. The cartoner may require the folded tail and printed panel to arrive in a controlled orientation, so the interface should be tested as a line rather than as two independent machines.
