Process |
|
|
The steps followed to create quality tin cans are:
|
|
|
|
|
| |
|
| Printing - Lacquering - Varnishing |
Tinplate sheets are printed according to design specifications of customers. An additional protective layer is added to the exterior of the containers, followed by inside lacquering. This process is used for food products, adding to their shelf life. Outside lacquering, mainly in gold, is used for decorative purposes. Varnishing adds
luster
and a touch of gloss to the printed plate, making it scratch resistant.
|
|
 |
| |
| Slitting |
The printed and lacquered sheets are trimmed to the required size, depending on type of container and components - sheets for cans and strips for component making.
|
|
 |
|
| Component Making |
The company has its captive production facility for components. Components consists of top viz., ring - lid - tagger (Aluminium foil). Manual or auto feed power presses, with various tools and dies that subscribe to specified dimensions and internationally accepted tolerance levels make these. The bottoms and rings of cans are lined with rubber, which act as a sealant, making the cans leak-proof and moisture-free. |
|
 |
|
| Welding |
The body blanks are rolled and welded on an automatic, side-seam, welder machine. |
|
 |
|
| Flanging - Beading - Seamer |
A multi-head flanger is used for flanging on both sides, so as to give a flare to the cylinder. In keeping with technology trends, HTWL has reduced thickness of tinplate to maximize strength of the product. This is augmented by beading on the cylinder, done with the help of a multi-head beader machine. The top surface is seamed on the cylinder of the can, using a multi-head seamier. |
