| The Production Process |
| |
The entire process is based on a
series of operations called Line Operations. Windsor Cans have adopted
the same, varying it sometimes according to the
clients requirement. There are total 8 stages in the process: |
| Slug Punching |
The slug is the
seed of a collapsible tube. Hence, in order to reap better fruit we must 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. Hence this allows a control over the purity and
quality of the aluminium being used. The purity ranges from 99.5% - 99.7%. |
|
| Slug Extrusion |
| 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. |
| Trimming |
| Trimming is the
next process ,which involves threading, shaving and trimming of the mouth and shoulder
of the tube. |
| Annealing |
Extruded tubes
have a hard surface, so in order to soften them they are annealed in the oven under a
temperature of 3500 C, so that they have the right degree of
softness –
which can be similar to that of plastic laminated tubes. |
| Lacquering |
| As a safeguard
against the chemical reactions between the tube and its contents, the tubes are subjected to
internal lacquering where the interior is uniformly coated with protective lacquer coating. |
| Coating & Printing. |
The coating &
printing machine is comprised of a coating machine and a 4-colour Offset machine
together with a drying oven, where 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. |
| Capping |
| The caps are
affixed in a separate room, where measures such as wearing special headgear are strictly
abided, in order to prevent entry of extraneous matter, like hair or dust, into the tubes. |
