An aluminium slugs for collapsible tube is obtained on a machine that cuts many slugs from a straight bar or coiled stock. The thickness, shape and size of the slug are set by a stop in the machine. A feeding mechanism feeds the aluminum bar or coil stock up against the stop and then a knife pushes against the aluminum material and shears of the slug. This is done at a fairly high speed of production. The cut slugs are then sent to a cold heading machine that reverse extrudes each aluminium slugs into a straight can shape. A plunger pushes against the slug inside a hole in a die and the material flows up the plunger to form a can. This is done in a full automatic production line where aluminium slugs are fed into the start unit of the line. They are then extruded, during which lips are rolled onto them. The inside of the shaped cans are lacquered, and next labels are rolled onto them. The finished empty cans are bunched together, strapped and stacked on pallets ready to ship. All the steps are done on one pro
duction line with no human touch from start to finish.
Aluminum collapsible tubes are one of the most common packaging solutions in cosmetic, health care, pharmaceutical, food and adhesive industries. They are ideal for packing low viscosity products, such as lotion, cream, ointment and adhesive.
The tube collapses as the contents are squeezed out, effectively preventing suck back of air or contaminants and thus maximizes shelf life of product.
Aluminium collapsible tubes, covered under IS: 3107-1979 (First revision), are suitable for a wide range of liquids, semi-liquids, pastes & formulations containing soluble constituents. All collapsible aluminium tubes with short screwed nozzle are well specified in this standard. The aluminium collapsible tubes with other types of nozzles designs eg. Eye ointment tube, are covered under IS: 7852-1975.
Aluminium collapsible tubes are manufactured from Aluminium grade 19500 as per IS: 737 – 1974. The wrought aluminium & alloys for general engineering purposes belong to this specification. The collapsibility & permeability w.e.f. moisture and easy workability are the main characteristics of the aluminium slugs used for manufacturing collapsible tubes.
Aluminium of 99.70% purity is cast, rolled to predetermined thickness & blanked to provide cylindrical shapes of a defined diameter. These metal pieces are generally referred to in the industry as slugs. Slugs are heat treated to bring them to desired metallurgical state for fabricating into a collapsible tube. Mechanical fabrication an aluminium tube is accomplished in five stages of production, carried out automatically on a mass-production flow line.
The lubricated slugs are converted into tube shapes, by a process of impact extrusion in a specially designed press, with a shoulder & nozzle. The tubes are transferred, next, to an automatic machining lathe for trimming to correct lengths & thread rolling on the nozzle portion.
The severe impact-extrusion forces, involved in the transformation of slug to tube, cause a work-hardening in the tube. To provide flexibility or collapsibility, in the containers, they are annealed at temperature slightly below the melting point of the metal.
It is intended to prepare a Feasibility Report to install a Aluminium Slug production facility with a capacity of 1800TPA as a Green Field Project.
