Vacuum assisted lost wax investment casting
process is used for making gold castings for jewellery items. |
 |
| |
|
|
Professional designing
experts make castings designs both manually and with computed aided
design (CAD) techniques.
|
 |
|
|
|
 |
Master-item are made by
master craftsmen manually and on CNC machines through computer aided
manufacturing (CAM) techniques. |
| |
|
 |
Rubber moulds are then made using globally approved quality of
rubber and liquid rubber. Both hot and cold processes are used for
making rubber moulds. |
|
Wax trees are then made using world best
wax available for the purpose. Each wax piece is manually cleaned and
checked to insure the final quality of casting. |
|
 |
 |
Investment powder resin of
internationally approved quality is used for making castings with
process parameters controlled as per powder resin manufacturers
recommendations including de-waxing and heat treatment cycle for
curing resin tree cavities. |
| |
|
Appropriate gold alloys are made in electric furnace at best suited
temperatures under controlled crucible atmosphere.
Grain refiners are used to provide fine
grained castings for best quality and appearance after polishing and
finishing.
Vacuum assisted casting machine is used to feed molten gold alloys in
resin cavities. |
 |
 |
Deburring machines are designed in-house
with suitable media and compound to give best results in terms of
quality, time and metal loss. Individual pieces are then hand polished
using right media for high gloss. |
We use, carefully selected and examined world's finest quality
gemstones to set in our products.
Polished casting are then cleaned for oils and greases. Ultrasonic
Cleaning is done before electro-less gold
plating as final finishing operation. |

Information processing and order
tracking
All order for manufacturing are allotted distinct job order nos. with
details of alloying, items to be produced and the customers name. The
job order no. Moves through all stages of manufacturing till it is
supplied to customer. Complaints, if any, from customer, therefore,
are traced back for any possibility of erroneous processing. For this
purpose we have developed computer software in-house. |
