In Gold Jewellery Manufacturing companies, jewels are polished using small magnetized pins in a washer machine fitted with powerful electromagnets at the bottom. This process may sometimes cause the tiny pins of 2mm length and 0.5mm Diameter to be stuck with small pores in the jewels. This causes reduction in quality of the jewels produced and needs to be removed. In the current scenario, the pin is removed manually which is time consuming and even after testing 5% of defects will occur.
So, in order to achieve 100% quality output jewellery manufacturing & retailing companies are looking for completely automated solution which classifies the jewelries containing ferrous impurities which should alerts the tester and segregative the defected and non-defected ones.
