In Order to produce a unique piece, the very initial step is to create a design. This is The Point from the Magic Begins. It is a stage where in the designer develops the idea for the design, evaluates the idea and translates it into reality.
CAD software is used to increase the productivity of the designer. Improve the quality and dimensional accuracy of design, and to create a database for manufacturing. Once a design is conceptualized in the mind of the jewelry designer, it is drawn on paper and then into the system.
Mould making is an integral part of the production process. It helps in creating multiple pieces of jewelry of the same design. These designs remain protected and embedded in the mould forever and it is possible to create replicas of the same in future.
Casting is a very complex process and requires utmost skilled and experienced casters for the desired final product. The wax tree is placed in steel flask which is then occupied with a slurry of chemical powder which solidify in an hour. The Flask is than heated in an electric furnace which melts the wax leaving behind a cavity of tree.
This Step involves the production of wax pieces from the rubber moulds made from the silver master. The rubber mould is placed on the commercial wax injector machine. Molten wax is Pressure injected into the mould cavity to create wax models for casting.
Once the raw casting is clipped off from the casting tree, it has a tiny nub leftover at a place where the gold piece was attached to the sprue. The polisher grinds off this nub using the motorized grinding machine, which acts as an abrasive to smooth the surface of the gold piece/ jewellery.
In Polishing, the idea is to add shine to the entire piece of jewellery. Polishing is done after setting of stones and it can be done either by hand or by machine. If the jewellery is hand polished, then the craftsman uses different tools like solid buff, soft buff, hair buff, coin buff, single line ball buff, green rouse for shine, platinum polishing rouse, black lustre for removing casting/filling layers, red rouse to impart shine and white lustre to remove roughness.
Quality control is a procedure or set of procedures intended to ensure that a manufactured product or performed service adheres to a defined set of quality criteria or meets the requirements of the client or customer. There are three different methods of quality control inspection which includes measurement, visual inspection and mechanical inspection.
