The Production Process

           The entire process is based on a series of operations called the Line Operations. Windsor Cans have adopted the same, varying it sometimes to suit the clients requirement. There are a total of 8 stages.

The slug is the seed of a collapsible tube. Hence, in order to reap better fruit – we sow the right seed. While custom-made slugs are being used, WIndsor Cans have always relied on the slugs punched out of Aluminium slug stock. Since this allow's a control over the purity and quality of the aluminium being used. The purity ranges from 99.5% - 99.7%.

Slugs, after being duly annealed are put into the extrusion press. This involves subjecting the slug to immense pressure, as a result of which it gets a moulded into a tube. This is a core extrusion job, contrary to the belief that aluminium foils are rolled up to make tubes.

Next is the trimming process ,which involves threading, shaving and trimming of the mouth and shoulder of the tube.

Extruded tubes have a hard surface. So in order to soften then up they are annealed in the oven under a temperature of 350⁰ C, so that they have the right degree of softness – which can be likened to that of plastic laminated tubes.

As a safeguard against chemical reactions between the tube and the contents, the tubes are subjected to internal lacquering there the interior is uniformly coated with protective lacquer coates.

The coating & printing machine is comprised of a coating machine and a 4-colour Offset machine, together with a drying oven, where in the tubes, duly lacquered, are passed through a conveyor belt. At Windsor, we have adopted Nylo-plates for sharper printing quality, instead of the usual zinc plate.

The caps are affixed in a separate room, where measures such a wearing special headgear are strictly abided, in order to prevent entry of extraneous matter, like hair or dust, into the tubes.
